Best Triathlon Bikes Tested & Compared


A triathlon is a race comprised of three separate circuits. You’ll be expected to exhibit the same level of endurance on each one. They usually include periods of running, swimming and cycling. The first two sports primarily require you and some light gear, but the cycling part requires something much more specialized. A triathlon bike is specifically designed for speed. It’s created to engage your most powerful muscles—your quadriceps. It does this by lowering your center of gravity and placing your hips over the crankset. This is one product that you absolutely can’t skimp on if you’re doing any type of competitive triathlon.

A regular bicycle allows you to push downward and propel yourself forward with the pedals. A triathlon bike actually forces you to push slightly back using your quadriceps, and opens up your airway. This propels you forward at a faster rate and can get you far ahead of your competition. The bike needs to be light, sturdy, and capable of withstanding speed and stress.

These bikes are also designed to engage your muscles in such a way as to allow you to transition to other parts of the triathlon faster. You’ll be able to hop off of the triathlon bike and go straight into a full sprint if need be. There’s none of the messy untangling that comes with a regular bicycle. These machines are scientifically designed and customized for the sport. By creating an aerodynamic flow, they decrease resistance and maximize your speeds.

We’ve reviewed some of the best triathlon bikes on the market and looked at them from an athletic perspective.

4. Specialized Shiv Elite

The Specialized Shiv was created to provide three key elements every triathlete needs: aerodynamics, fuel, and fit. These bikes are all about integration, and very few bikes represent total integration better than the Shiv. The Shiv Elite from Specialized ignores UCI regulations to create a triathlon specific bike complete with the unique 'Fuselage Hydration System' that is built into the frame improving aerodynamics and reducing the need for retrofitting additional equipment.
Expand to see more
Comfort / Stability:

The way this model differs from many other triathlon focused bikes is in the fact that it doesn’t really ride like one. The ride is actually closer to that of a road bike. You won't get any of that teetering around, or that unbalanced feeling you might get when becoming familiar with a tri bike for the very first time. The overall control seems to come fairly easy, and has the kind of maneuverability that allows you whip around those surprise potholes and take sharp corners with confidence. The design of the tubes was done in a way to to pull the centered pressure that you might get from crosswinds more downward, reducing the effect that tends to push you offline, in turn actually increasing your ability for forward momentum.

It might be difficult to believe, but when that wind really picks up, it almost seems like the bike corrects itself before you start reacting to right it. The brakes are also really smooth, which is kind of nice given how well the bike picks up in speed. The internal hydration system provides the same amount of fluid as a traditional water bottle but can be topped up on the go without creating any additional drag. The frame is made from Specialized FACT 10r carbon and, as you can see from the side profile, has an enormous down tube and seat tube, typical of the modern day aero triathlon bike. The Shiv Elite is finished off with Shimano 105 drivetrain and AXIS 2.0 wheelset.

Durability/ Quality

Very stable in cross winds regardless of the big girth and its head and down tubes. The shapes of the tubes have been devised to pull the center of the pressure created by crosswinds downwards, to reduce their stability to push you offline and increase their ability to push you forward. The brakes are smooth and helpful since Shiv picks up speed pretty fast.

Cost or Value:

you are really getting performance quality for a fairly competitive price tag.
  • They are not grabby but they have the power to keep a tight rein on your speed when necessary.
  • Picks up speed fast.
  • Provides total integration.
  • They are direct mount rather than the traditional calipers.

5. Cannondale Slice 105

In an era where we see triathlon and time trial bikes adopt enormously thick down tubes and profiles to create the aero advantage. Cannondale claim the Slice is the 'the world's' lightest Tri frame, with the best stiffness-to-weight'. A well as the mechanically designed compliance of the seat and chain stays, the Slice comes with 'AERO SAVE' micro-suspension technology that absorbs road vibration, further improving the ride comfort.

Comfort / Stability:

Cannondale has gone the other way, relying on 'Truncated Aero Profile ‘shapes of the Slice tubing to create a fast yet comfortable bike. The difference is apparent when looking at the Slice from the side: much less material which saves on weight, and ultrathin seat and chain stays that aid comfort.

Durability/ Quality:

It packs easy and has a normal stem. Normal parts mean less packing for the races. A 1 1/8 steered folk, standard. Full housing inside the frame (meaning no energy drink fouling the house/cable interface) standard. Direct mount Shimano brakes, standard. Its, mechanical and D12 compatible. And no fearing or forgetting proprietary parts.

Cost or Value:

Cost friendly and definitely a god deal for any cyclist.
  • Light bike, good geometry
  • Best stiffness to weight
  • Really drops the ball on aerodynamics
  • Direct-mount only brakes

6. Giant Trinity Advanced Pro

  • Very affordable for any racer to purchase as it is lower priced than other triathlons.
  • Comes with a tubeless wheel that enhances comfort throughout your races and increases speed.
  • Has plenty of storage spaces for hydration and some of the racers essentials.
  • Its known and tested to be the fastest bike in the world.

Its crankset appears as standard thus meaning it cannot come as larger or ancient cranksets  which are seen in most triathlon bikes.

Now, if you’re new to triathlons, the main difference between a tri bike and a traditional road bike is the geometry, or the frame, and the angle of the seat tube (the long piece of tubing that extends from the bottom of the bike). A triathlon bike has a steeper seat tube angle than a road bike, so it’s closer to vertical. This steeper geometry places your hips over the crankset (where the chains attach), which engages your quads more. Not only does this position give you a better power output, but it actually makes the transition to the run easier since you’re relieving strain on some body parts and engaging others.


The Criteria We Used For Our Evaluation of the Best Triathlon Bikes

Triathlon competitors are the best of the best. For the biking portion of their race, they need more than a set of wheels that will get them through a loop around the park.  They need a bike that can handle rough terrain and tackle obstacles, all while being fast. Triathlon bikes are definitely a specialized piece of equipment that can make or break an athlete’s race.

The criteria we looked at when creating our list are specifically geared towards increased performance and comfort. A product is no good if it causes injuries or makes it more difficult for you to complete your circuit. These triathlon bikes have been tried and tested under some of the most strenuous conditions in the world.


Triathlon bikes are engineered based on a geometric formula that increases their speed and aerodynamic capabilities. While speed is usually the top consideration, it’s important to make sure that the rider is able to keep control of the bike. The last thing anyone wants is a high-speed crash in the middle of their race. The harder a rider has to work to keep the bike on the road, the more energy they’re exerting that could be better used elsewhere. A good triathlon bike will allow the athlete to be seated in a forward leaning position. This lowers their center of gravity and increases their balance. Stability is definitely something we took into consideration when reviewing these products.


One of the most important components of any triathlon bike is the seat. It’s set at a steeper angle that allows the rider to sit in a more aerodynamic position. This allows the person to bend at the hips and to push out using their quadriceps. Part of the design is based on creating a heightened level of comfort for the rider. This allows them to focus on their performance, and less on stressed muscles. During some races, a triathlon bike may be used more than anything else. This is when comfort becomes key in your ability to compete and perform well during the race.


Few things are as embarrassing as having a piece of equipment fall apart mid-race. Think of your triathlon bike as an investment in your athletic prowess. You want it to stand up to punishing conditions while continuing to maintain its structural integrity. It’s important to look at the materials that a bike is made out of. You want a lightweight build that’s as simple as possible. The fewer features, the less likely it is to break or get weighed down.

A lot of serious athletes and professionals use bikes with a carbon modular build. This is extremely lightweight and portable, but it comes with a price. These bikes have a tendency to be fragile, and extremely expensive. If triathlons aren’t something you’re considering as a lifelong athletic accomplishment, then you may want to invest in something that’s not as pricey.

Some More To Think About

There are other details that you should consider when selecting a solid bike to add to your arsenal of workout equipment. The purchase you make should provide you with a bike that can handle the terrain on which you will be riding, but also moves you quickly and safely.  It should also fit your lifestyle needs, whether you are a serious triathlete or an occasional racer. To help make this decision a little easier, below are some extra features you should consider when shopping for a new model.


Triathlon bikes are extremely unique and may not be able to be serviced by a regular bicycle shop. Maintenance is definitely something you need to consider before making your purchase. This is an item that you’re going to be using under stressful circumstances, and this means that it’s more likely to sustain damage. If your triathlon bike is from a foreign company, this could mean ordering very expensive parts from overseas.

It definitely helps if you choose a model that you’re capable of maintaining yourself. Always look at the parts and the way that they’re used on the bike. This can make you aware of areas that experience a higher level of wear and tear. This is also another factor we looked at when reviewing these products and creating our list.

Your Race Participation

The type of bike you choose needs to meet the demands of the types of triathlons in which you are competing. If you are racing on a road course, a road or racing bike is probably the best choice for you. If your races involve trails or mountain terrain, you will most likely benefit from having a mountain bike. Do you race on both? A hybrid might be a good choice for you, or even having one of each type of bike (if you really want to splurge).


These can be found at a varying range of prices, from inexpensive to top-of-the-line gold standard. However, you should purchase a bike that fits within your budget but also meets your racing needs. If you break the bank on your bike purchase, how will you pay you race participation fees?




Q: What makes a triathalon bike different from a regular bike?

The biggest difference between a tri bike and a traditional road bike is the angle of the seat, which is also known as the saddle. The angle of the seat determines how a rider is positioned on his or her bike.

A triathlon (racing) bike has a steep seat tube angle, forcing the rider forward into a crouch, which is a more aerodynamic position, enabling the rider to go faster.

A traditional road bike has a shallower seat tube angle. This allows the rider to sit back. It is a more comfortable position for long rides or when encountering uneven terrain.

There are a few other differences… keep reading to find out what they are!

Q: Do I really need a triathlon bike?

This really depends on how serious of a triathlete you are. Most beginner-friendly races will be filled with participants that use whatever bike they had laying around in their garage, which is perfectly fine to start out.

However, once you plan on becoming more dedicated to racing, you should consider upgrading to a bike that is fit for this type of competition. There are four main types on the market: road, mountain, hybrid, and triathlon. The differences between these bikes are as follows:

  • Road Bike: A road bike is characterized by skinny tires and a skinny frame, with a typical seat tube angle of 73 to 75 degrees.
  • Mountain Bike: This type of bike usually has wider tires and a deeper tread pattern to deal with off-road rides and obstacles. The seat tube angle ranges from 71 to 75 degrees.
  • Hybrid Bike: A hybrid bike is similar to a mountain bike in that is will usually have wider tires and deeper treads than a road bike. However, a hybrid bike is meant to be ridden on roads and light-off road courses, and is not necessarily meant for the heavy duty-obstacles that can be found on mountain trails.
  • Triathlon Bike: A triathlon bike is also known as a time trial bike. Their frames and tires are skinny and are intended to be ridden on roads. The real difference between a road bike and a triathlon bike is in the handles. A triathlon bike will have aerobars in place of traditional-style handles. This helps make the bike more aerodynamic to increase speed. Triathlon bikes usually have a seat tube angle of 75 to 80 degrees.

Now that you have this information, think about the type of courses you race. Select the type of bike that is best suited to your race type.

Q: What is a seat tube angle and why is it important?

If you thought you were done with math classes like geometry when you finished high school, you were wrong. There is a special kind of geometry, called bike geometry, that is used to engineer bicycle frames to optimize performance. The seat tube angle is just one of the features of a bike frame. It is the angle made by the tube that supports your bike seat in comparison to the ground.

A steeper angle will position your seat, or saddle, forward, while a shallower angle will position the seat further back. Steeper angles are better for racing because it allows the rider to crouch into a more aerodynamic position. Shallow seat tube angles is better for more relaxed riding, as it transfers the weight to your hips and glutes.

The steepness of the seat tube able varies by bike type.

  • Road Bike: 73 to 75 degrees
  • Mountain Bike: 71 to 75 degrees
  • Hybrid Bike: 71 to 75 degrees
  • Triathlon Bike: 75 to 80 degrees

Most bikes have adjustable saddles, so you can move it to meet your level of comfort and to enhance your performance.

Q: What are the most important features I should look for in a triathlon bike?

The features you choose are really dependent on the bike course portion of your triathlon.

If you will be riding on a road course, this type of model will likely serve you best. They are lightweight, aerodynamic, and are designed to move you fast and efficiently along roads and paved surfaces.

If you will be competing on a trail or mountain course, you will want a mountain bike. Wider and heavier than racing bikes, they are engineered to withstand impacts and rugged terrain. A mountain bike will get you through a course safely and efficiently.

So, the bottom line is to know your race, and select a bike that can meet the demands of the bike course.

Q: Which is more important in a triathlon bike: speed or durability?

This is really a personal choice, however, the terrain on which your triathlon is taking place should be a factor that is given serious consideration when choosing speed or durability.

Fast bikes are usually racing bikes. They have light and aerodynamic frames that are usually pretty stiff. The tires are narrow and the handlebars are of a non-traditional, aerodynamic style and are usually set lower on the bike. The seat of a racing bike is also steep, forcing you forward into a crouching position. Racing/Tri bikes use caliper brakes to slow the bike down without affecting the weight. Racing/Tri models are made for flat, road or track conditions.

Mountain bike, on the other hand, have wider frames and wider tires with deep treads. Together, these allow the bike to absorb heavy impact and handle the uneven, rugged terrain that is usually encountered on trails and mountain paths. They also have shock absorbers to help handle impacts, and their frames are built to withstand crashes (it happens!). Mountain bikes have disc brakes which are more effective in stopping the bike in muddy or wet conditions. They also have a less steep saddle angle, forcing you back on the bike. Mountain bikes are nearly twice as heavy as racing bikes, which makes sense considering they are engineered to be ridden on trails and unpredictable terrain.

When selecting a bike for speed or durability, it is really important to consider the type of race in which you’re competing. A racing model won’t serve you well on a mountain trail, and a mountain bike will surely slow you down in a road race. Choose wisely!
