Frame and forks at £899, complete builds from £1649.

Faster, lighter, stronger full carbon disc brake road bike for Alpine cols, fast and stable descents, and long days in the saddle; the bike for endurance racing and taking on the Alps.
Think of the Indian Pacific Wheel Race, the Pan American Highway, the Transcontinental. Colibri is inspired by such ultra-long distance endurance routes, striking the balance between pace, handling, and comfort.
Compliant and stiff, the carbon frame is ideal for ultra-endurance racing; engineered for crossing continents and letting the miles fly by.
With clearance for up to 28mm tyres, Colibri is responsive and forgiving: a rewarding ride that eats up billiard-table smooth bitumen yet can more than handle odd sections of grit.
A comfortable climber, Colibri’s longer chainstays make for fast, controlled descents and confidence inspiring handling, allowing you to go further for longer at greater speeds.
The ride is further enhanced by a full carbon fork with tapered steerer and headtube, giving precise cornering and increased feedback and capably handling the unfamiliar lands and tricky situations that come with the territory of longer self-supported rides.
An all-season endurance racer, Colibri takes on all road conditions making it ideal for the Fred Whitton or the mountain climbs of the Tour de France. This is the bike for Galibier, Ventoux, Glandon, Alpe d’Huez, Bealach Na Ba, Bwlch-y-Groes, Wrynose, the list is endless.
Go light. Go fast. Go far.
