Features400 Series OCLV Ultra high performance, within reach. The areal weight range and modulus mix of 400 Series OCLV provides an exhilarating sense of acceleration and confident handling. BB90 Wider is better BB90 is the widest bottom bracket available on a road bike. This Trek-exclusive carbon BB makes the frame lighter, stiffer, and quicker to accelerate. Tapered Head Tube The Bontrager E2 fork tapers from a 1.5" lower bearing to a 1-1/8" upper bearing. The larger-diameter lower bearing keeps the E2 fork stiffer under cornering loads and distributes forces more evenly, increasing the life of the bearings. Result: a more confident and durable ride. DuoTrap Computer Sensors - The end of zip ties DuoTrap seamlessly integrates the computer sensor into the frame to measure speed, distance, and cadence with no added aerodynamic drag. It works with all the major ANT+ wireless technology players, including Bontrager, Garmin, Powertap, and SRM. Direct-mount front derailleur Provides accurate shifting in a lightweight, minimal package H2 fit H2 retains all the handling geometry and ride characteristics of our pro-fit H1 platform, with a slightly higher head tube height to put less strain on a rider’s back and neck. It will also accommodate riders with slightly less pelvic rotation and core stability. The H2 higher head tube is the right way to get most riders in the right place. No goofy high-rise stems, no huge stack of spacers—the look is nothing but pro. Crank: compact Two front chainrings with shorter gearing, for the best combination of climbing ability and flat-terrain speed. Crank: triple Three front chainrings for a wider gearing range.
