Trek's IsoSpeed fork is ingeniously engineered with reversed dropouts, increased fork rake (offset) and a constant, gentle curve beginning at the crown and sweeping all the way to the axle. These brilliant innovations allow the fork to absorb shocks rather than transmitting them to the rider for optimum comfort and energy savings, and they also increase the fork's lateral stiffness for more control.
Trek’s IsoSpeed design uses a pivoting decoupler device to allow the seatmast to move independently from the the seat tube of the frame, allowing for vertical compliance at the saddle while maintaining efficient power transfer.
|Trek's Boone features a 90mm-wide bottom bracket. This extra width allows Trek to build frames with larger-diameter tubes for improved power transfer. The BB90 bearings are placed directly into the frame to save weight. The combined weight-savings and improved power transfer ensure additional pedaling efficiency and simplify maintenance.|
