What Are Triathlon Bikes?
Triathlon bikes are bicycles specifically designed for a triathlon, which is a three-sport endurance event involving swimming, biking, and running. Triathlons range in distance from Sprint to Ironman, which is said to be one of the toughest endurance tests in the world.
The biking portion of a triathlon typically lasts from 20 minutes to six hours and is ridden as an individual effort.
As opposed to criterium or road racing like we see in the Tour de France, triathlon biking is typically an individual time trial where drafting is not allowed. That means that your bike speed is determined by only you – your aerodynamics, power output, and speed.
Most triathlon bike courses are flat and straight, with some (if any) corners or hills to navigate. This is one of the reasons that triathlete bikes are heavier and more aerodynamic than road bikes.
With more aerodynamic tubes and aero bars, triathlon bikes sacrifice some cornering and climbing ability. But on most triathlon courses, the extra straight-line speed is well worth the sacrifice.
In triathlon, the run portion always follows the bike, which means that triathlon bikes need to be comfortable.
You wouldn’t want to step off the bike and go straight into a 10km run with a sore back, cramping glutes, and fiery quads.
Especially in long-distance triathlons (half Ironman and Ironman distances), it is crucial to ride a triathlete bike that is equally fast and comfortable.
That’s why you’ll see extreme-looking saddle and handlebar positions on most of these triathlon bikes. It takes some getting used to, but these triathlon bikes are actually quite comfortable, even while riding in the aero position.
Let’s jump into our list of the best triathlon bikes which includes bicycles for every level of triathlon and which are suitable for any triathlon distance.

How to Choose The Perfect Triathlon Bike
Unless you’re a professional bike mechanic, it can be hard to see the difference between many of the most popular triathlon bikes.
Even among the best triathlon bikes in our list, the differences may seem only marginal. Do 15 grams even make a difference?
When choosing the perfect triathlon bike, there are three things you must consider: aerodynamics, weight, and value.
Your bike’s straight-line speed is arguably its most important feature. Next to that is weight, which matters more or less depending on your training and racing terrain.
Lastly, and most importantly for some, is the value of your triathlon bike. We’ll tell you how to get the biggest splash for cash when choosing the perfect triathlon bike.
Aerodynamics
Triathlon bikes are all about straight-line speed. After your body position (which is crucial for speed), your aerodynamics are next determined by the profile of your triathlon bike’s frame and wheels.
In the triathlon world, the better your aerodynamics, the faster you go. In some cases – windy days, hilly routes, or technical courses – the most aerodynamic frame is not always the best.
But in most triathlons, you’ll want the most aerodynamic triathlon frame and wheels.
Generally, you can look at a triathlon bike and wheels and see how aerodynamic they are.
The more material the better, and the most aerodynamic frames have thick frame tubing, deep sectioned wheels, and a rear disc wheel. This is the fastest straight-line setup that is suitable for most triathlons.
But, as we’ll see in a minute, it’s also the most expensive.
Weight
There was a long-held belief in cycling that lighter was always faster.
And while this is true on an hour-long climb, it is not always true on the flat.
In fact, power and aerodynamics are far more important than the weight on flat roads, which covers the majority of triathlon racing.
During a flat, 40km time trial, it does not matter if your bike weighs 18 lbs or 28 lbs. But as soon as the road tilts up and down, weight becomes a factor.
The steeper and longer the climbs, the more important weight is to triathlon performance. Consider your training roads too: are they flat, hilly, or mountainous?
On hilly or mountainous terrain, a lightweight triathlon bike may be better than a heavier but more aerodynamic triathlon bike. In addition, the faster you go, the more aerodynamics matters than weight.
Thus, beginner triathletes are more apt to use lightweight triathlon bikes, while elite-level athletes will be faster on a heavier aerodynamic frame.
Value
Perhaps the biggest obstacle to purchasing a triathlon bike is the price. While baseline models may cost around $2,000, higher-end triathlon bikes can cost upwards of $10,000 when you include aerodynamic race wheels.
When choosing the perfect triathlon bike, you want to get the biggest bang for your buck. The answer is a combination of your current ability and future triathlon goals.
In the sport of triathlon, the better you are, the narrower the margins are between first and last.
This is when high-end race equipment becomes even more critical when the difference between 1st and 10th could be just a few minutes. For competitive triathletes, it makes sense to invest more into getting the perfect triathlon bike.
But for beginner triathletes, the difference between competitors is more often down to fitness and experience than their equipment choices.
As a beginner or intermediate-level triathlete, you will benefit more from structured training and minor equipment purchases like a new helmet, running shoes, or carbon race wheels.
A special note for long-distance triathletes such as Ironman competitors: due to the extra long training hours, it is best to invest in a triathlon bike right away.
The more time you spend in the saddle, the more important it is that you have an excellent frame, a comfortable saddle, and aero bars that you can spend hours in.
Just as Ironman athletes invest more time into their training, it makes sense to invest more into your triathlon bike to maximize comfort and performance.
Frequently Asked Questions
What kind of bike is best for a triathlon?
Triathlon bikes are the best bikes for triathlons. The only exception would be if you are a complete beginner and have never ridden a triathlon bike before. Riding in the aero bars is an aggressive position that can take some getting used to, so it is better for beginner triathletes to start with a road bike for triathlons.
Most triathlon courses are straight and flat, and there is nothing faster on that terrain than a triathlon bike. If your triathlon course is uniquely hilly or technical, then it may be better to race on a road bike; but this is a rare case.
Is a triathlon bike worth it?
A triathlon bike is worth the cost for competitive triathletes. There is nothing faster in a straight line than a triathlon bike. A road bike with clip-on aero bars is not even close. In order to achieve your fastest times and compete near the top of your category, you need a triathlon bike for triathlons.
If you’re worried about the investment, remember then you can resell your triathlon bike if it doesn’t work out. As long as you keep your triathlon bike in good working condition, you will be able to resell it for a good chunk of the original price.
If in doubt, start with a road bike for your first few triathlons. Then add clip-on aero bars when you’re ready to be more competitive. Once you want to compete for the win, go with a full-on triathlon bike.
Is a road bike OK for a triathlon?
Yes, most triathletes start on road bikes for their first few triathlons. This is because road bikes are more versatile than triathlon bikes, and you can use road bikes for training, racing, climbing, group riding, and more.
When you’re ready to upgrade your racing set-up, you can even start with attaching a pair of clip-on aero bars to your road bike. This allows you to go faster in a straight line without having to invest the time and money into setting up a whole new triathlon bike. But for serious triathletes, there is nothing faster and more comfortable than a triathlon bike.
What’s the difference between a triathlon bike and a road bike?
The main differences between a triathlon bike and a road bike are frame shape and aerodynamics, aero bars, and wheels.
Triathlon bikes have thicker and more aerodynamic tubing than road bikes which are heavier but faster in a straight line. Whereas road bikes have drop bars – handlebars with three available hand positions – triathlon bikes have aero bars which are time-trial-specific handlebars with long extensions for your forearms.
Lastly, triathlon bikes have deep-sectioned wheels and sometimes rear disc wheels which are heavier but faster than shallower road bike wheels which are designed for climbing and all-around riding.
Why do triathletes use TT bikes?
Triathletes use TT bikes, or time trial bikes because triathlons typically involve an individual effort rather than group riding. The only exception is Olympic-style triathlons which allow pack riding; but in these triathlons, racers use road bikes instead of TT bikes.
For individual effort, TT bikes are faster than road bikes. This is because TT bikes are more aerodynamic than road bikes. And during an individual effort, you don’t need to worry about pack riding skills such as braking or positioning.
Is a triathlon bike faster than a road bike?
Yes, a triathlon bike is faster than a road bike on a straight and flat road. Triathlon bikes are much more aerodynamic than road bikes thanks to their unique tube shapes and time-trial-specific handlebars. Though triathlon bikes weigh more than road bikes, there is no significant penalty for increased weight on flat roads.
Road bikes are faster than triathlon bikes when it comes to climbing and descending since road bikes are lighter than triathlon bikes, and they also handle much better in corners.
Why are tri bikes heavier than road bikes?
Triathlon bikes are typically heavier than road bikes because they use more materials. Whereas triathlon bikes are designed for straight-line speed, road bikes are designed for a mix of speed, cornering ability, and climbing. Thus, road bike frames have thinner tubes and less overall material to keep them lightweight. Road bikes typically have lighter and shallower wheels which are lightweight as well as aerodynamic.
On the other hand, triathlon bikes have thicker aerodynamic tubes which use significantly more material than road bikes. Triathlon bikes also have deep-sectioned wheels, and sometimes rear disc wheels, which are super aerodynamic, but also significantly heavier than shallower wheels used on road bikes.
