The Trek Boone 5 Disc is a carbon cyclocross race bike that's built for crushing any CX course – even the most legendary on the UCI circuit. The sleek, lightweight carbon frame has terrain-smoothing Rear IsoSpeed and is trimmed with parts that perform in any conditions, like a capable SRAM Apex drivetrain, vibration-absorbing handlebar and powerful disc brakes that deliver stopping power in bumpy, muddy terrain.
