What is a Time Trial / Triathlon Bike?

Time trial (TT) bikes are designed with a single focus: pure speed. This  at the expense of everything else including comfort, handling, and … err … expense!

In bike design, improving aerodynamics (of the bike/rider combination).  The rider’s position on the bike has by far the biggest impact on speed. For this reason, TT bikes share the following features:

  • Very aggressive frame geometry
  • Aero rather than drop handlebars
  • Disc rear wheel
