Trek Boone 6 Disc Cyclocross Bike 2021
The Trek Boone 6 Disc Cyclocross Bike is smooth, compliant and race-ready, crafted from OCLV carbon for rapid, weight-saving efficiency and built with cross-specific components to truly conquer the circuit. The addition of front and rear IsoSpeed makes for a seriously smooth ride that heightens rider control and diminishes fatigue from tough courses, boasting stiffness whilst pedalling and compliance when seated. Tyres can be run tubeless to eliminate pinch flats at low pressures, or, in contrast, can be run at high pressures due to the small amount of suspension provided by IsoSpeed.
Aggressive, cross-specific geometry and tube shapes mean this bike lends itself to easy shouldering, whilst Shimano GRX 11-speed components provide a range of gearing options for undulating terrain, with superior chain retention and an improved grip on the hoods and levers. The single chainring means simplified post-ride or race maintenance, and Bontrager CX3 Team Issue tyres deliver unfaltering traction in critical moments.
Highlights
- Designed with input from cyclocross royalty, including World Champion Sven Nys and US National Champ Katie Compton
- Carbon rules on the cross course – it's lighter, more forgiving and more efficient than aluminium
- The combination of Front and Rear IsoSpeed cuts down on the fatiguing impacts of rough courses and increases compliance, giving you more traction when it matters
- Boone's cross-specific geometry and tube shapes make shouldering easy so you can dominate all aspects of a race, including run-ups
