Building a triathlon bike can be a daunting task, but with the right knowledge and tools, it can be a rewarding experience.
The first step in building a triathlon bike is choosing the right frame. Triathlon bikes typically have a more aggressive geometry than road bikes, with a steeper seat tube angle and a more forward position for the rider. This allows the rider to maintain a more aerodynamic position, with their body leaned forward and their elbows tucked in close to the body. The frame should be made of high-quality materials, such as carbon fibre, which is lightweight and stiff and provides good aerodynamics.
The next step is choosing the components. Triathlon bikes often feature integrated brakes and shifters, which are integrated into the base bar or aerobar. This improves aerodynamics and reduces weight. Additionally, many triathlon bikes also feature internally routed cables, which further reduces drag and improves the overall aesthetics of the bike.
Wheels and tires are also important when building a triathlon bike. Triathlon bikes often use deep-section wheels, which are designed to slice through the air more efficiently. However, deep-section wheels can be more affected by crosswinds, so many triathlon bikes also feature wheels with a more rounded profile to improve stability in windy conditions. The tires should be high-performance, lightweight, and have low rolling resistance.
Aerobars, also known as aero-bars, are a key component of a triathlon bike. These handlebars allow the rider to maintain a more aerodynamic position, with their body leaned forward and their elbows tucked in close to the body. Aerobars can be adjusted to fit the rider’s body, and they should be comfortable and easy to use.
The final step is assembly. This is where all the components are put together and the bike is fine-tuned to fit the rider’s preferences. This includes adjusting the seat height, handlebar position, and other settings to ensure a comfortable and efficient riding position.
It’s also important to remember that a triathlon bike is not just a one-time purchase, but also a long-term investment. The bike should be maintained and serviced regularly to ensure it is running efficiently and safely. It’s also essential to be comfortable with the bike, so it’s recommendable to take it for a test ride and make any necessary adjustments before the race.
In summary, building a triathlon bike is a complex and detailed process that requires the right knowledge, tools, and experience. Choosing the right frame, components, wheels, and tires, and putting them together in an efficient and comfortable way is key to having a successful triathlon bike. It’s also important to keep in mind that a triathlon bike is a long-term investment, and it should be well maintained and serviced regularly.
