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.

You get durability and capability with SRAM Apex XPLR's clean shifts and huge gear range
This bike was designed with input from cyclocross royalty, including World Champion Sven Nys and US National Champ Katie Compton
Rear IsoSpeed cuts down on the fatiguing impacts of rough courses and increases compliance, helping you to ride stronger for longer
Boone's cross-specific geometry and tube shapes make shouldering easy, so you can dominate all aspects of a race, including run-ups
Carbon rules on the cross course – it's lighter, more forgiving and more efficient than aluminium
