Time Trial (TT) & Triathlon Bikes – The Fastest Way to Ride Solo

Time trial bikes are the Formula 1 cars of the cycling world—fully optimised for solo efforts against the clock. Whether you're doing a UCI time trial or a long-course triathlon, a TT bike is built to maintain speed in the most aerodynamic position possible for extended periods.

These bikes are not made for general road riding. Their extreme geometry can be uncomfortable and unstable at lower speeds or in group rides. But if you're racing solo or doing long-distance triathlons, there’s nothing faster.

What makes TT bikes unique?

• Aerobars: Allow you to tuck into a low, narrow position to reduce drag.

• Longer wheelbases: Help with straight-line stability at high speeds.

• Deep tube profiles and disc wheels: Minimise turbulence and improve efficiency.

• Positioning: Extremely forward-leaning, sometimes using steep seat angles (77–81°) to optimise hip rotation for running off the bike (in triathlons).

TT bikes often require custom fitting to dial in position, and many triathletes invest in wind tunnel testing or fit services to get the most from their setup.

Who should choose a TT/Tri bike?

• Time trial racers

• Triathletes (especially long-distance)

• Riders looking to maximise solo speed on flat terrain
