About this bike
Your competitors will be envious when you show up on your Speed Concept 9.8, if they ever actually see you fly by. One of the most-advanced triathlon and time trial aero bikes, its hand-built-in-the-USA Trek carbon frame boasts Kammtail shaping that cheats the wind even in cross winds. Plus the truncated shape is lighter and stiffer for excellent acceleration and cornering. The Speed Concept's unparalleled aerodynamics is also courtesy of ingeniously hidden cables, brakes, wheel quick releases and even the computer sensor. The 9.8 is also one of the most adjustable tri/TT bikes out there so you'll enjoy a custom fit for the best possible power output. And, this clock-beater features SRAM's precision Force 22 components, plus deep-dish Bontrager wheels that fly down the road. Your PRs are about to fall.
