Criteria Used for Evaluation

Comfort

Outside of aforementioned features such as the fork, triathlon bikes will sport certain seat tube angles and top tube lengths to create a more comfortable experience. But, what you can do is also assess the adjustability and design of the saddle. These are two enormous design integrations that need to be focused on for specific reasons.

In terms of the adjustability, all people have different bodies and shapes and each bike may fit you differently. There typically are multiple bike sizes available so make sure you get the size that contours to your body the best. But, even so, the adjustment system needs to be present and fluid. However, it goes beyond adjusting the cockpit back and forward as you may want to also look for the front pads to be adjustable. In terms of the saddle design, triathlon bikes have versions that are specifically optimized for the sport. Their shorter nature takes the pressure of your pelvis for enhanced comfort for longer rides.

Durability

The performance side of things for a bike is important in its own right but it is amplified for a triathlon bike. After all, a triathlon is a competition and your bike should be up to the challenge of outperforming its competitors. Of course, it all starts with the aerodynamics and because these types do not feature the restrictions of time trial bikes, innovation can be key. One design feature that some manufacturers like to implement is oversized tube profiles for their bikes. Basically, this enhanced size allows the wind to pass along the bike without deviation. The result is enhanced speed and decreased drag.

But, another essential component to look at is the fork. This will assist with the speed and the comfort, in fact. As the fork is mainly designed to act as a shock absorber for your bike and deflect in on the tire, you get a faster and more comfortable experience with a high-quality fork design.

Materials

Let’s just be honest; there is a lot that goes into deciding on an elite triathlon bicycle. Why else do you suppose they are so darned expensive? If you are looking for a starting point, though, you might as well start off with the construction as a whole. More specifically, the frame and other components such as the brakes and the cables. In terms of the frame, there are several different types that you can look into. For starters, you have carbon fiber frames and these are ideal if comfort is your priority.

Of course, there are also aluminum frames and these are quite common for triathlon bikes. One of the main benefits of aluminum is its excellent combination of sturdiness and weight. Then, though, there are also titanium frames and this is where things can get really expensive. Titanium is much like steel except it is much lighter and is ideal for durability and versatility. It is not just the frame that you need to assess, though. You can also look at how the bike increases the aerodynamics. For instance, you may see brakes hidden behind the forks or internal cables to protect them from damage.

Speed

How terrible would riding bikes be if they were all made with a single speed drivetrain? Look, single-speed bikes are not awful but painfully limited as you are stuck with one pedal speed no matter what you do. What is interesting about triathlon bikes, though, is the focus is a little different for the gear system. Sure, you could focus in on the ranges and ratios of the system but in reality, you may want to simply assess whether the drivetrain is electric or mechanical. The difference is fairly huge and here is why.

As you can imagine, the more convenient and popular option would be an electric gear system over a mechanical. First of all, it completely removes the tedious cable routing process present in mechanical gear systems. But, it also means you never need to move your hands to the bar end when you want to shift. There are several trademark companies that offer these types of drivetrains, but Shimano is a name that comes up time and time again due to their reliability. Then again, it is not all sunshine and rainbows as you need to ensure the electrical gear system is charged up before the big event.
