Time Trial & Triathlon Bike Frames

Time trial frames are made for speed. In time trial races the rider is not allowed to draft (ride in another riders slipstream) which therefore means the emphasis needs to go to aerodynamics and materials used. To aid the aerodynamics the front forks are very flat, helping to cut through the air, and the vertical down tube is often shaped to the rear wheel and within millimetres of the tyre.

Time trial or TT bike frames are normally made from one of three different materials. They are:


The pros are that steel frames are relatively inexpensive, strong and easy to work with. The con is that it is quite heavy, making it less competitive for those seriously into their triathlons or time trial riding.


The beauty of carbon is that it can be shaped into almost any form and is super lightweight yet strong. These features are in part why carbon is one of the more expensive option in terms of materials.


Compared to steel frames, alloy frames have a lower density and strength however, they do have a better strength-to-weight ratio, which makes them the usual preferred option over steel frames.
