Best Entry-Level Triathlon Bikes for Beginners

1. Cervelo P-Series Triathlon Bike

Cervelo P-series Triathlon Bike

Cervelo is one of the leading brands when it comes to triathlon, and the P-Series is its entry-level offering.

Cervelo’s P-series has long been a favorite among triathletes looking for an aerodynamic edge. The new models improves on the old design, with better aerodynamics and a more similar shape to Cervelo’s top-of-the-line P5. 

The P-series is a great choice for triathletes who want a fast bike that’s still easy to work on and adjust. We appreciate that Cervelo has kept triathlon roots alive with features like a zippered top-tube nutrition pocket and an aerodynamically tuned down tube water bottle. And of course, the included rear hydration mount makes it easy to stay hydrated on long rides. If you want more, you can add other accessories such as a front mount hydration bottle.

The front seat tube and nose has been designed to mimic bayonette fork without the complications of it. And, the design team did succeed.

The extended seat tube cut out. The bike’s seat tube cut out is a close-fitting curve in the seat tube. What does this do for you? It shields your rear wheel’s leading edge to block wind and improve aerodynamics.

Overall the bike is designed with stiffness in places where it’s most needed. For example, the bike is stiffer at the bottom bracket and its torsional region. This makes it easier to handle, go around corners faster, and for you to plan your accelerations.

Cervelo has also thought through the fit range of this bike carefully, offering six sizes to ensure that riders of all sizes can find a comfortable position. As a result, the P2 is a fast, comfortable bike that is sure to appeal to triathletes and time trialists alike.

Overall, the Cervelo P-series is a great choice for anyone looking for a fast, lightweight bike that’s ready to race.

2. Specialized Shiv Sport

Specialized Shiv Sport triathlon bike

The Specialized Shiv Sport was created with aerodynamics, usability, and high-quality rides in mind. All these features make it ideal for either time trials or non-draft triathlons.

What makes this one of the most usable and accessible bikes?

It’s a one-stop bike.

One frame will fit a multitude of systems. This means you can be sure that any component you want to upgrade will be compatible with this bike.

You can describe your ride quality by how comfortable you are on your bike.

Specialized tries to create a comfortable ride for you so it designed its bike for its intended use.

For its triathlon bike, it focused on static and dynamic comforts to make an overall high-quality ride. The ride has the optimal ratio between stiffness and weight. This ensures you can confidently handle the bike and have a significant power transfer.

To make this bike more aerodynamic, Specialized created its seat tube cutout, which is a close-fitting curve in the seat tube. This design shields the edge of the rear wheel and improves aerodynamic performance.

The bike comes with deep-rimmed wheels, which actually can withstand gusting side winds. You might not panic as much with these wheels and Specialized’s stiffly-designed bike during a windy ride.

Another feature worth mentioning is the bike’s saddle, Specialized Sitero Comp, which although not the lightest, it does give you a lot of stability. This means you can be sure that no matter how hard you peddle, you won’t slip out of the saddle.

I’d recommend this bike to anyone who is looking into their first triathlon bike. It’s like an “everything” road bike. You can upgrade the parts and other components easily so you won’t have to upgrade to a new bike. This saves you money and time of getting used to a new bike. The bike’s stiffness might give you more confidence when you handle it and you can focus on pedaling yourself forward.

The QR PRFour Disc has the same frame and power of PRSix Disc with the consistency and security of disc brakes.

And, it’s one of the most affordable performance racing bikes since the base price starts around $3000.

What tech and specs make this bike worth looking at?

While this may not be considered a “superbike” it does have Profile Design aero bars. This brand has a multitude of aero bars and extensions to choose from along with bases. This makes it very easy to find a pair that works for every rider. Remember, that you can only reap the benefits of the aero bars if they’re fitted correctly to you and you feel comfortable in them.

The bike combines Shimano 105 11-speed components with TRP disc brakes, which makes the bike have lateral stiffness and stability. This is what you’ll need when you want to handle your bike at high speeds and handle it in cross or headwinds.

The bike has a standard front end, Shift+ technology, and boat tail airfoils. This makes it easy for the bike to be worked on and easy to travel. You’ll need two allen wrenches if you do your own repairs or plan to pack your bike.

Triathletes who have bought this bike say that it feels like it was made for them. It feels like they are moving with the bike and they’re working as a team together. This is, of course, after all the adjustments have been made and a bike mechanic tuned the bike to their measurements. Triathletes also like that the bike is easy to work on in their own homes if they choose. And, they are easy to pack for flights to destination races.

I highly recommend this bike if you’re looking for one with some high-end components but don’t want to spend tens of thousands of dollars on one. This bike can be worked on and improved so you’ll be sure it will stick around for a while.

6. BMC Timemachine One

Bmc Timemachine One Triathlon Bike

As an overview, the Switzerland-based company created their triathlon bike with a Shimano 105 11-speed drive train, Shimano RSO10 wheelset, BMC Aero Post, and Profile TT Handlebar.

The bike’s Position-to-Perform (P2P) system lets you find your ideal contact point to optimize and maximize aerodynamics no matter if you want a very aggressive or more conservative position in the saddle.

To make the bike more aerodynamic, BMC experimented with its tube shapes. This means the bike comes with truncated profiles and a super-lean frontal area that makes the bike very stable in crosswinds.

The V-Cockpit and the Flat Cockpit technology is great if you’re on a long ride and don’t want to stay in a very aggressive position. You can use either of these two cockpits without compromising aerodynamics because you’re tired of being in a super aero position on the bike.

Of course, there’s integration on the bike, like other triathlon bikes. It has an integrated brake system that leaves more room in the frame for storage. There is a rear mounted equipment storage box, tube top fuel compartments, and a dual downtube bottle cage. All that can help you get through your longer races.

I’d highly recommend this triathlon bike, it has all the basic components of a middle to a high-end road bike with building priority of multi-sport athletes in mind. If you’re looking for your second or even your first, I’d look into this option. You might be surprised that this is the bike for you. The different options for aero also make it ideal especially if you’re not used to riding in the aero bars and need to give your arms and back a break.

Mid-Range Triathlon Bikes for Ironman

1. Trek Speed Concept

trek speed concept triathlon bike

is one of the most tough-looking bikes you’ll see on the course this year. The bike itself looks like a cross between a triathlon bike and something The Dark Knight might ride if he rode a bike.

The bike’s specs and performance live up to its looks.

This is an “ultra-grade” aerodynamic bike with the most up-to-date technology available. It’s well-designed with a well-thought-out frame.

Speed Concept’s frame has been meticulously engineered for aero gains. It is 180 grams lighter than their previous chassis. The fork has been designed to provide stiffness and control while the headtube provides aerodynamic benefits. The seat stays are designed to provide stiffness and strength while the rear triangle helps to dissipate road vibration. All of these features combine to create a frame that is both light and stiff, providing the ultimate in performance.

Ultra-light 800 Series OCLV Carbon is actually a step-up from its predecessors. The design team reached the crossroad between price and value when putting together this bike.

The aero bars that come with the bike are made of carbon fiber and have a large range so you can find your “perfect” fit.

Trek is designed for efficient storage and easy access to hydration and nutrition supplies while bicycling. The Speed Concept’s storage system is designed to help you stay hydrated and fueled without compromising your aerodynamic position or sacrificing performance.  

The downtube water bottle has been integrated into the frame, which helps to reduce drag. Additionally, Trek offers an optional between-the-arms water bottle, which can further decrease drag. Finally, the Speed Concept is equipped with an integrated Bento box, which can be used to store up to eight gels. This not only saves space, but also helps to keep the rider more aerodynamic.

When it comes to stopping power, disc brakes are superior to rim brakes in any condition. They work by squeezing a brake pad against a spinning disc, or rotor, which is attached to the wheel. This action slows down the wheel, and ultimately the bike.

Disc brakes are more effective in wet and muddy conditions because they are less likely to clog with debris. However, one downside of disc brakes is that they can add weight. Trek team has optimized the design of the fork and wheels to only add an extra 170 grams. By comparison, most disc brake designs add 450 grams of weight.

2. Canyon Speedmax CF 8 Disc

Canyon Speedmax CF 8 Disc Review

The Canyon Speedmax CF 8 Disc bike is known for its DT Swiss Arc 1600 wheels along with Shimano Ultegra groupset that makes this bike ready to race.

If you’re looking for a time trial/triathlon bike, where price and performance meets, this might be your bike. It won’t break the bank, and the components are nice for a mid-level triathlon bike.

This bike comes with a Selle Italia saddle, Profile Design 35A aerobars, and Canyon’s high-quality finishing components really push this bike to the top. It also has a carbon seat post, base bar, and wheels to make it look even more impressive.

Canyon installs its own integrations such as its storage box, which is great for storing triathlon racing essentials, such as a small repair kit and nutrition, or even out for a long ride.

If you want more integration tools, Canyon can install hidden brakes, integrated hydration system, and its own aero bars.

Be warned, the aero bars run wide, so if you are more petite you might have a harder time finding the right fit.

The braking system is reliable and you can stop with confidence so you can speed when you want and break only when you need to.

The only drawback to this bike, is the long crank arms, especially if you’re a smaller triathlete.

Although the price tag is not cheap, this bike is well worth it and I’d recommend it if you’re really serious about triathlons and slicing a few more seconds off your overall time. The bike doesn’t require too much attention other than making sure it has your specific specs. You could buy it on a weekend and race on it the next.

3. Cervelo P5

Cervelo P5 Triathlon Bike

This Cervelo P5 is appropriate for those who consider themselves a mid to high-level triathlete who wants to make every second count on the course. It’s best suited for those who race Olympic distance races and longer.

And, for those who are eager to race, this bike comes ready to race. You won’t need to buy new accessories or transfer ones from your old bike. The P5 comes with a bento box, a downtube bottle, and back seat hydration already installed. If you want to pay a little extra, you’ll get a Vision front mount hydration bottle.

Additionally, the bike also has a cable cover that is integrated with a bento box. It’s practical and makes the bike look clean.

The P5 is light and stiff. It will help you go faster on the course and your bike will respond well to the terrain and how you handle it.

The bike was designed so that the rider and bike work together to take up as little frontal space as possible. If the rider knows an aerodynamic position, the bike takes care of the rest. The bike’s components were designed to take up as little space as possible and provide a powerful engine to its riders.

While this bike sounds high-end and exclusive, all parts are easily updated and replaceable. You can buy a frame from Cervelo and be assured you can upgrade any part at any time. This means you can “grow” and become a more confident biker with your Cervelo.

Depending on the components and what “extras” you’d like on the bike it can run between $3200-7000.

Triathletes who have bought, trained and raced on this bike like it because it’s actually different than other Cervelo models and helps them race faster. The frame is stiff and light which makes it easy to handle and corner and turn smoother and with little effort. The carbon fiber frame absorbs most of the road’s vibrations which makes it very comfortable to ride on for long races.

I highly recommend this bike to high-level triathletes who have been racing for a long time and want better equipment for their next A-race.

4. Felt IA Advanced

Felt IA Advanced triathlon bike

The Felt IA Advanced surpasses its predecessor since it upgraded from rim to disc brakes. And so, the frame was made to support the strength of disc brakes. And, the frame is designed to give riders a high-quality ride and enhance stability and handling response.

Additionally, the newest Felt IA has a user-friendly and well-fitted single head tube cover, which makes maintenance and adjusting easier compared to other models.

The rear disc brake has a triangle shape around it which makes the bike more stiff and responsive to stopping, of course, but also sharper shifting. This triangle also puts all your pedaling power to the rear wheel so that your stroke is efficient and every once of energy pushes you forward.

The bike has a high clearance so that it can accommodate tires up to 28mm depending on the rim size.

The bike has both tube top and seat tube storage. The tube top storage is integrated and has enough space for riding essentials that riders can easily access. The rear seat tube storage is ideal for biker’s flat-repair kit. And, it doesn’t create any drag for the aerodynamics.

Triathletes who have bought the bike say that the acceleration is seamless and happens very quickly. Most triathletes have been able to handle the bike well in cross and headwinds. And say cornering is easy. Every rider is a big fan of the integrated storage. They say that they can fit all the essentials they need and it doesn’t interfere with the aerodynamics. All triathletes say to make sure that the cockpit and aero bars fit properly before walking away with this beauty. Otherwise, you’ll end up frustrated on a bike not built for you.

I recommend this bike for those who want a bike a little nicer than the QR, just reviewed, in terms of components and materials. This does put it at a higher price point. But, be sure that the bike fits properly, especially the cockpit dimensions and aero bars.

Most Expensive High-Performance Triathlon Bikes

1. Quintana Roo PRsix2 Disc

quintana roo prsix2 disc

The Quintana Roo is an excellent elite-level road bike with high-quality features with room to grow with the bike and upgrade parts.

Like the other PR series, this bike has SHIFT + technology and QBox Storage system, but this bike has a few differences especially in the carbon layout and being budget-friendly.

Before talking about the bike’s performance, let’s briefly talk about the bike’s features.

To make this bike aerodynamic, the team designed an asymmetrical downtube to direct airflow away from the drive side of the bike. All of this helps the bike cut through the wind and might help you save energy on the bike. All in effort so you can have more energy and muscle strength for the run.

The QR team uses Boat Tail airfoil shapes to make the bike more stable and aero. The shape is made to prevent air pockets from accumulating around the back tube. This, in turn, reduces drag and increases aerodynamics and stability on the bike.

The bike comes equipped with Shimano Ultegra Di2 Electronic series drive train to help give you a reliable performance during training and race day.

Depending on your budget you can either buy very deep-rimmed (71mm) Enve SES 7.8 wheels to be even more aerodynamic. Or, Shimano RS370, which have a ride profile that you can rely on for seasons to come.

On the road, the bike is lightweight, responsive, and stable. The best you can ask for on any ride. It feels comfortable to go fast on the bike and still feel fresh enough for the run.

I’d highly recommend this bike if you’re looking into your first road bike or even an upgrade. You can get all the features of a more expensive bike for far less. And, best, yet, you might even take this bike with you for many seasons to come.

2. Scott Plasma 6

Scott Plasma 6

The Scott Plasma 6 is a triathlon bike that was designed with aerodynamics in mind. It has a number of features that make it fast and adjustable to fit a variety of riders. The frame is made from carbon fiber and is lightweight and stiff.

The Syncros engineering team focused on creating a system of base bars, extensions, and saddle positioning to allow for a huge range of adjustability. This makes the bike perfect for people of all sizes and riding styles. The bike comes with either a SRAM RED eTap AXS 24-speed groupset or Shimano Ultegra R8050 22-speed Di2 groupset, depending on the price point you select. It also includes Zipp 808 NSW carbon clinchers, Schwalbe PRO ONE TT tires, and Syncros Belcarra 1.0 TRI saddle.

Scott’s Plasma 6 triathlon bike is designed for speed and efficiency. The biggest indication of this is the bike’s wheel positioning. Scott understands that in the real world, the smallest movements of the front wheel create a lot of drag-increasing turbulence. To help offset this, the company has designed the down tube around the front wheel to be more aerodynamic. This allows for less drag and more speed, making it a more efficient bike overall.

Scott has also determined that taking the moving rider into consideration when optimizing airflow around the bike is important. This results in a more complex design but one that ultimately performs better. With these design considerations, Scott has created a faster, more efficient triathlon bike that is sure to perform well in competition.

The Plasma 6 is the latest in a long line of triathlon-specific bikes from Scott. It builds on the successes of its predecessors by integrating storage and hydration solutions into the frame while also improving aerodynamics. This makes it easier for athletes to fuel themselves during long rides and races. The bike also features a number of other inconspicuous storage solutions, such as a gel bottle stored above the bottom bracket and a storage box behind the seatpost.

Whether you’re looking for your next race bike or a bike to help you train for your first triathlon, the Scott Plasma 6 is a great option. It’s fast, adjustable, and comes with all the features you need to have a successful race day.

3. S-Works Shiv Disc

S-Works Shiv Disc

is a work of art aesthetically and for its components. It’s a machine on two wheels and is definitely on the higher-end of triathlon-specific bikes you can shop around for.

The bike was made so that the rider is well integrated and will be incredibly aerodynamic and handles crosswinds well. And, it’s packable for all your far away races and is extremely adjustable so you get the most comfortable fit possible. Of course, like other Specialized bikes, this one comes with the Hydration and Nutrition Fuelcell system ready to go.

Compared to other Specialized triathlon bikes, the Shiv Disc moved its Hydration and Nutrition Fuelcell from the inside of the bike to the back of it. So it looks hidden from the frame and makes the bike even lighter. And, with the new location, there can be more fluid stored on your bike. It makes “hiding” your nutrition simpler if it’s all in one spot.

The downtube now features “A New Shape of Speed” which can store a lot of nutrition. And, can be removed to access the Di2 A-Junction Box or your repair kit.

If you fall on either extreme of the height spectrum, Specialized thought ahead. The frame comes in four sizes and even then can be dialed up or down depending on your body type. The point is to find the most comfortable position that will make you aerodynamic.

Of course, other parts of the bike can be adjusted to fit your specific body height and your comforts on the bike. Aero bars, extensions, and arm pads are adjustable as well as the cockpit. This almost ensures that you’ll feel like you and your bike will move as one unit.

Triathletes who have bought this bike love it because it has so many adjustable options and fits a wide range of triathletes. The bike can be used for any type and distance of triathlon. It’s not too specialized but provides the right support for whatever triathlon goal they have. The new nutrition system works well and it does make the frame lighter but having more room for snacks does weigh it down a bit. Triathletes said at most they can have 10-12 gels, 4-5 bars, and 5-6 chews depending on their nutrition plan for a race.

This bike does come with a high price tag, but it might be worth it if you need a big upgrade or want a new bike.

I recommend this to anyone who wants a bike with a lot of room for storage and has a light frame. This is also a good option to consider if you’re on either extreme of the height spectrum. The company can work with you and help find the size and measurements that are suitable for you.

Triathlon and Road Bikes – Buyer’s Guide

Triathlon Distances and Formats

Before I jump into the specifics, let’s quickly discuss the different triathlon distances and even the format of them. This will definitely influence your decision.

If you don’t know, already, a triathlon can take you either under an hour or over 15 hours to complete depending on the distance format. This means you can be on the bike for at least 30 minutes or possibly over 6 hours.

The two formats a triathlon can have are draft-legal and non-drafting. The majority of age-group events don’t let you draft. This means you must be at least five bicycle lengths or 12 meters behind the person in front of you. Exceptions of course when you’re passing.

In other words, in a non-drafting race, you cannot put yourself at an advantage by riding the wheel of the person in front of you.

For non-drafting races, many triathletes choose triathlon bikes instead of road bikes. This allows them to have the best aerodynamics without drafting. These bikes also have highly developed integration, and storage; while trying not to compromise comfort.

On the other hand, draft-legal races such as International Triathlon Union (ITU) races, World Champions, and even the Olympic games, allow triathletes to ride the wheel of the person in front of them.

In draft-legal races, time trial bikes are not allowed and road bikes must meet the UCI road bike regulations.

To sum up this part, all four distances (sprint, Olympic, half Ironman, and full Ironman) can be non-drafting races, where triathlon bikes can be used. However, only sprint and olympic distances are most likely to be draft-legal and road bikes must be used.

Road Bike vs. Tri Bike vs. Time Trial (TT) Bike

One of the most frequent questions, is what is the difference between a road, triathlon, and time trial bikes?
It mainly has to do with the geometry of the bike’s frame, specifically the seat tube angle.

If you’re not sure what the seat tube is, it’s the long tube that reaches down to the bottom bracket up to the seat itself. The angle of the tube is relative as if there is a horizontal line that runs through the bottom bracket.

triathlon bike vs road bike frame

On a traditional road bike, you’ll have a 72-degree seat tube angle. While a triathlon bike starts with 76-78-degree seat tube angle.

Muscles Used

On a road bike, the seat tube angle puts you in a position where you use muscles such as your hamstrings and quads. This is great if you’re just doing the cycling, but after the bike, your legs will have to adjust to running.

This is where triathlon bikes come in.

The theory, to this day, is that if you’re riding in a more forward and aerodynamic position you use your quad muscles less. And, thus saving them for the run after you jump off the bike.

Triathlon and Road Bike for Your Needs

But one of the more important ones is the type of area you train and race in.

For example, if you live in a mountainous or hilly region, you need a bike that allows you to use all your leg muscles when you’re climbing up long and winding hills. A road bike would be ideal in this situation since you get the most power from sitting further back from the handlebars.

If you were on a triathlon bike trying to go up a hill, the bike’s geometry might force you to back out of the saddle just to stay in an aerodynamic position. This is not only uncomfortable for you, but also very inefficient.

You’ll hear people argue points from both sides when it comes down to it.

Many say that a good set of wheels make up for the inefficient geometry when you’re climbing hills on a triathlon bike.

While others point out that a traditional road bike can be made into a triathlon bike. You can change the seat post or buy clip-on aero bars.

Another factor is what you’ll use your bike for.
If you’re just using your bike for triathlons, then a triathlon bike might be a good option for you.

However, road bikes are very versatile and can be your “everything” bike. This is especially important if you bike outside of triathlons or even go on bike tours.

Buying a tri bike isn’t the wrong choice, just read further so you can pick the right one for you.

If you’re sure, at the point in the article, you need a road bike, you can skip to the product review.

Before going into the specifics of a triathlon bike, I’ll briefly tell you about time trial bikes.

Time Trial Bikes

Time trial bikes are a sub-genre of triathlon bike and are one of the most specialized bikes you can buy.

A time trial bike, while similar to a triathlon bike, has some differences.

For example, you’re not positioned so aggressively on the bike since no part of the bike can be three times longer than the rest.

Time trial bikes must adhere to the International Cycling Union (UCI) rules, which means that the tip of the saddle must be 5cm from the center of the bottom bracket.
And, time trial bikes are more commonly used for cycling races so it’s built with that purpose in mind.

The bike is good for shorter races, but not for Ironman type of events.

Triathlon Bike Specifics

To give you a more complete description of a triathlon bike, I’ll give you information about the fit, frame, gearing/components, saddle, handlebars/aerobars, and wheels.


A rider’s comfort strongly influences how a bike is built and triathlon bikes aren’t the exception to this rule.

Triathlon bikes need to make the rider feel comfortable in the saddle for long periods of time in the aero position. This affects how the rider feels after the bike and starts the run.

As a result, triathlon bikes are aggressively built so that the seat tube angle starts at 74-degrees and can go over 80-degrees.

This very aero and aggressive position are hard to maintain so to fix this, the crank length is often shorter than on road bikes. This helps you if you don’t have the flexibility or lack mobility in your lower back and hips.
Triathlon bikes also have a longer tube top and an elongated reach to put riders in a more horizontal position. This technology ensures that a rider’s weight is evenly distributed over both wheels.


Like any bike, aerodynamics is the main factor when they are being built.

Triathlon bikes come with more stops on the design map since they need to incorporate storage for any nutrition riders need for long races.

Often, triathlon bikes are built with oversized tube profiles, which makes the wind pass by the bike without creating drag. Oversized tube profiles are often found on a bike’s front forks, downtube, and seat tube.

Triathlon bikes also have hidden features such as brakes, cables, and storage. For example, the brakes are often found somewhere where the front forks are or behind the fairings of the bike.

Internal cables are being used over external ones since they aren’t prone to weather conditions.

And, finally, the wheels make triathlon bikes more aerodynamic. These bikes come with deep rims to help slice through the air.

Integration and Storage

I’ve mentioned storage in the previous sections, but let’s dive into now.

Integration for storing your nutrition on the bike is not just a part of the aerodynamic design, but a practical one especially once you get out on the course.

Storage comes in different forms since bike companies have gotten creative with it.

For example, some bikes have a front hydration system that can hold as much water as your water bottle. This helps you stay in aero while keeping yourself hydrated.

Other bikes have an integrated toolbox located between the front and rear wheel, which is great for storing extra tubes and tools.

Nearly all brands have a food storage box integrated on the top tube.


Triathlon bikes go beyond gear ratio and range since they already have the best on it.

The real choice comes between buying a triathlon bike with electronic or mechanical gearing.
Electronic gearing lets you shift gears from both time trial bars and the brake bars so you don’t have to come out of aero to shift. This also streamlines the shifting process since the bike has internal cables.

Be sure that if you go with electronic shifting that you’re all charged up for race day! The last thing you need is to be stuck in an extreme gear.


Saddles on triathlon bikes are meant to put riders in a more aggressive and aerodynamic position.

Compared to road bike saddles, they are shorter with the middle section cut out to take the pressure of soft tissue of the pelvis.


The purpose of the extension handlebars is to keep your wrist in a neutral position and keep your elbows and shoulders at a right angle. While this position seems odd, it actually provides good base support and won’t affect other parts of your body.

Extensions can come in different shapes and it depends on your comfort level.

Most extensions come in a straight, curved, or pointed upward shape. Try out a couple and figure out what works best for your body.

Keep in mind you might be in that position for hours at a time.

Road Bike Specifics

If you’re reading this part of the buyer’s guide, then you’re definitely buying a road bike.

Like the previous section, I’ll provide detailed information about the bike such as the frame, geometry, etc.

There are some components not found on a road bike such as storage and aero bars, but I will get into that in the following subsections.

To get a base understanding, road bikes are versatile and can be used to compete in high-level triathlons or for social rides and staying in shape.

From there you have different options, and we can begin the discussion there.

Types of Road Bikes

There are a few different road bikes out there for you to choose from. So as not to overload you with information, I’ll briefly describe each kind.

Aero Bikes

These bikes are made for speed and comfort so weight isn’t so much a priority for the rider. You’ll also find deep-rimmed wheels and nearly everything is integrated such as the brakes, cables, and shifting.

Generally, these bikes have a larger tube profile to reduce drag and increase stiffness.

Endurance Bikes

Compared to traditional road bikes, Endurance bikes longer wheelbase, head tube, and a less aggressive geometry for rider comfort.

Often, these types of bikes are made from the same material as light-weight bikes such as carbon fiber.

Lightweight Bikes

For lightweight bikes, the name of the game is keeping weight down.

These bikes aren’t made to be aerodynamic, they are made with the lightest materials and are best used if you’re climbing hills

Gravel/Off-Road Bikes

Gravel/off-road bikes are made so that the rider can bike anywhere, which makes them one of the most durable bikes on the market.

These bikes have a higher bottom bracket so riders can go through obstacle courses and wide clearance for fat tires. The gear ratios are lower so that riding off-road or in extreme conditions can be easier.

Touring Bikes

Similar to gravel/off-road bikes, touring ones aren’t so concerned with aerodynamics and lightness.

These are built for comfort and long rides if the rider is going from one city to the other.

You’ll often see these bikes with fender and rack mount for saddle bags.

Touring bikes are typically made of steel and its upright geometry helps the rider feel stable to help while carrying a heavy load.

Recreational Bikes

Recreational bikes help riders get from A to B and are well suited for new riders or those who like to do a lot of social rides during the summer.

You’ll find flat bars, wider tires, and an easy gear ratio on these bikes as they are supposed to get the rider to enjoy riding with others.

Frame Material

For triathlon bikes, they are all made with carbon fiber or other light materials, which are easy to mold into different shapes. And that’s why triathlon bikes sometimes come in some interesting forms.

For road bikes, you have a handful of choices to choose from. And, it all depends on what you’re going to use your bike for.

Carbon Fiber

Carbon fiber is one of the best materials you can find on a road bike. It has an optimal balance between lightness and stiffness to give you a comfortable ride. The carbon helps to absorb most of the bumps you would feel if you were on an aluminum bike.

The only disadvantage of an all-carbon bike is its fragileness. The material is prone to cracking if there is a large amount of stress put on an area such as a crash’s impact. You can compromise the carbon if you over-tighten the bolts on your bike as well.

Once the carbon has been compromised, you’ll need to either replace or repair it. Otherwise, it is unsafe to ride.


Aluminum is the next lightest material after carbon fiber and has some of the same properties such as lightness and stiffness.

These bikes have a strong power transfer thanks to aluminum’s stiffness and the tube’s thickness.

Often, so that the rider won’t feel the vibrations of the road, aluminum bikes will have carbon forks.

A downside to this material is that it will wear down over time, but with proper care, it can last for years to come.

Aluminum can be a good option if you’re looking for high-performance but on a budget.


Titanium is relatively light-weight compared to steel and is more durable than aluminum and carbon fiber.

Titanium is one of the most difficult materials to work with, so it does make the bike more expensive compared to an aluminum or steel one.

Titanium is the strongest of the materials I’ve discussed so far. The material is so durable that it stays resilient even after a crash. It takes a lot to break a titanium bike.

New building and machining techniques allow titanium bikes to be light and have all the riding comforts of an aluminum or carbon fiber bike.


Steel, while still a solid option for a road bike, is best if you’re buying a gravel/off-road or touring bike. They will last for a long time and can be your “forever” bike.

Group Set/Drive Train

A bike’s engine is its brakes and drivetrain, no matter if it’s a road or triathlon bike.

A drivetrain is made of cranks, chainrings, chain, cassette, derailleurs, and shifters. All these mechanisms help move the bike forward as you pedal.

The better the drive train, the more efficient, durable the ride becomes, and the shifting is nearly seamless. Of course, this comes with a high price tag.

Entry-level group sets are made of low-grade aluminum while higher ones are made from carbon fiber and titanium.

For a more detailed rundown of a bike’s group set/drive train check out this article.


A gear ratio is a combination of the number of chainrings found on the front and the number of teeth on those chainrings; and the number of cogs and the number of teeth on the cogs in the back.

Now that you have the definition of a gear ratio, you’ll understand when I say that gear ratios vary greatly and it largely depends on the bike’s purpose.

Most road bikes will have two front chainrings with 53-teeth for a regular set-up and 39-teeth for professional and high-level athletes. Generally, a smaller chainring has easier pedaling ratios.

For the back gears, it cassette’s cogs can be changed to make the gear ratio easier or harder for the rider.

Most cassettes have either 10 or 11 cogs and the smallest ratio is 11-25 while the largest is 11-28.

What does this mean?

If you have an 11-25 cassette ratio, the smallest cog will have 11 teeth while the largest has 25.

If you have a big difference between the small and large cog, the more the chain has to move when you shift gears. This makes your pedaling speed inconsistent while you change gears.

A bike with an easy pedal ratio will have smaller chainrings on the front and a larger ratio cassette on the back. This also gives the rider a large range of gears and pedaling rations.

The opposite of this is for bikes built for speed and have a smaller range of gears.


The last part to talk about are the wheels of the bike.

If you remember from a previous post, I talked all about wheels and that it’s basically made of a hub, that the wheel spins around, the spokes connecting the hub and rim, and the nipples which connect the spokes to the rim.

A wheel’s depth and width indicate how it will feel during a ride.

Your bike, if you buy an entry-level to intermediate level, will come with aluminum wheels of various qualities.

Are triathlon bikes worth it?

Triathlon bikes are absolutely worth it if you are passionate about the triathlon, and looking for an edge on your competition, a triathlon bike may be just what you need.

If you are new to the sport of triathlon, you may be wondering if a triathlon bike is worth the investment. After all, triathlon bikes can be quite expensive. However, there are several factors to consider that may help you make your decision.

First, if you are well trained and have a strong passion for the sport, you will likely get more use out of a triathlon bike than someone who is just starting out. Second, triathlon bikes are designed specifically for aerodynamic efficiency, which can give you a competitive edge in races. Finally, if you want the best possible equipment to help you reach your goals, a triathlon bike is definitely worth the investment.

So, if you are ready to take your triathlon training to the next level, don’t hesitate to invest in a quality triathlon bike. It could just be the key to unlock your potential as a competitive racer.

Does a triathlon bike make a difference?

For the uninitiated, a triathlon bike might not seem all that different from a standard racing bike. However, there are a few key features that make a triathlon bike ideal for the demands of long-distance racing.

First, triathlon bikes have a more aerodynamic design, which helps to reduce wind resistance and increase speed. Second, they are often equipped with larger gear ratios, which makes it easier to maintain a high cadence over long periods of time. While a triathlon bike is not essential for every race, it can certainly give you an edge on the competition

What type of bike is best for triathlon?

Deciding whether to use a road bike or triathlon bike for a triathlon is a difficult decision. Road bikes are more versatile and can be used for a variety of activities, including road racing, time trialing, and even cyclocross. However, they are not as aerodynamic as triathlon bikes.

Triathlon bikes, on the other hand, are designed specifically for triathlons and are therefore more aerodynamic. They are also often lighter than road bikes, making them easier to ride on long distances. Ultimately, the best type of bike for a triathlon depends on the individual rider’s preferences and needs.

What is special about a triathlon bike?

A triathlon bike is designed with the specific needs of a triathlete in mind. The seat tube angle is steeper than on a road bike to allow for less tension on the quadriceps and hamstrings.
Storage features are more abundant for convenient access to necessary items during the race. Triathlon bikes are wind tunnel tested to make sure that each detail from the frame down to the wheel contributes to making the rider as efficient as possible.


Choosing a road or a triathlon bike, no matter if it’s your first one or an upgrade, is exciting and a big deal. While this list is a good start to your bike search, be sure to get fitted at your local bike store! There you can tell them your needs, budget, and goals for biking. They’ll help you from there.
If you’re an experienced triathlete, be sure to read the return policy if you’re buying from an online store.

  1. hello
    just read your article about road bikes
    I want to change my Giant TCR 6 years old and I am not sure of what to choose
    I saw 3 options, Giant TCR Advanced Pro Disc, Cannondale Systemsix and Orbea Orca Aero M20i
    I do cycling tours and competitions in mountain type profile but also I compete in Thriatlon in summer so I want the balance to be able to keep those activities but with a significant improvement on the bike
    What would you recommend? My worry is to buy a too agressive aero bike and then have problems uphill
    Also my back suffers if I go in aero position all the time
    Thank you for your comment

    • Hi Sandra,

      From your options, I recommend Giant TCR Advanced Pro Disc. Systemsix and Orca are not as good for climbing as Giant.

      • How about a Cannondale CAAD12-13 or a Specialized Allez? What is your opinion of reversible seatposts for triathlon and road use ??

  2. Does anyone know how to get ahold of the Diamondback Andean 1? Numerous publications have touted it’s abilities but they have been out of stock on the Diamondback web site for well over a year

    • More info from ST:
      “I contacted Diamondback directly and was told that the frames are currently in production at their factory and they expect deliveries to begin around the end of the month.

      On one hand, this sounds much like the messaging posted here in March. On the other hand, if its not shipping sometime soon, that will be enough to convince me to look to spend my money elsewhere. I’m holding out hope that there were production issues earlier this year, and we will see the 2019 model available soon. “

  3. Hey Ryan
    Just sold my old and much-loved Specialized transition expert from 2010. I’m a decent age-grouper and I’m happy with my Mavic cxr wheels so looking for a complete frameset and any help appreciated. I’ve thought about this (ok I dreamt about this) and some of these requirements are to ensure compatibility between bikes

    1. 51/52 frame
    2. suitable for HIM. Ideally onboard/in-frame hydration possibilities. not sure how widespread this is
    3. rim braking
    4. ideally a tad better carbon than my old Speccy Trans Expert
    5. ultegra mechanical
    6. 11spd
    7. I run sensible 25/23 tyres, nothing too wide
    8. I might even favour an older 2018 era frameset if i can save some $$$.

    many thanks for any pointers! My brain only sees cervelo and specialized. so i need the advice of someone a little more open-minded 😉

    ty in advance

  4. Hi Mark,
    Cervelo and Specialized are great, but you can also check out these bikes:
    Quintano Roo PRFive and PRSix, Canyon Speedmax CF or even Trek Speed Concept.
    Not an easy choice, good luck! 🙂
