Time Trial Bike Framesets

A time trial (TT) bike frameset is specifically designed for aerodynamic efficiency and speed in time trial and triathlon events. These framesets typically feature aerodynamic tube shapes, integrated cockpit designs, and often include features like deep-section aero forks and seat tubes to reduce drag.

The latest TT framesets available at Sigma Sports from brands such as Trek and Pinarello prioritise positioning the rider in a more forward, aggressive stance to maximise power output and reduce wind resistance.
