Bombtrack Tension 1 700c Cyclocross Bike - Matt Rock Gray - 2021

The perfect introduction to cyclocross. With a competition-legal build paired to a light aluminium frame and carbon fork, our entry-level racer provides everything you need to get started. Sram’s Apex 1 groupset supplies hydraulic disc brakes for consistent control in the worst conditions. Helping you always find the right ratio, its single-chainring 11-speed gearing is easy to operate and service. A small concession to those starting out, its wide-ratio cassette prevents stalling if you run out of energy mid-race, while also allowing for greater versatility when not competing.
