The Tension 1 is the perfect bike for those wishing to start working their way up the cyclocross ranks. With its competition-ready legal build, our entry-level racer gives you everything you need to start earning those podium places with a competent aluminium frame and lightweight carbon fork. A Sram Apex One groupset with single-chainring 11-speed gearing – though wide for Elite level racing – will leave you enough in reserve lest you stall mid-race or enjoy taking it easy in the off-season.
