Combine the speed of a road bike with the comfortable riding position of a mountain bike and you have GT's Tachyon 1.0. Its lightweight aluminum frame and carbon fork efficiently transfer your energy into forward motion and handle predictably. With 30 gears, Shimano's Ultegra triple drivetrain has enough gear range to climb any hill or reach high speeds on the flats. And the sweet parts continue with WTB's renown Devo saddle, Tektro's powerful linear-pull brakes and Shimano's fast-rolling wheels with Vittoria tires.
