When you’re ready to graduate from a touring bike to a zippier ride—one with the streamlined speed, stiffness, and low weight to tackle a race but enough gears to let you climb any mountain pass—hop on this svelte option. Its full-carbon frame has the energy transfer and agility of a more expensive ride, and the smooth 105 triple-group shifters give you ten gears, for both efficient climbs and power on the flats.
