Light, fast, responsive and smooth. Really smooth. The Colibri Al glides up long climbs and it’s an assured and confident descender. Quick when you want it to be, relaxed and easy to pilot when you want to take it easy. It’ll take up to 36mm tyres or 32mm with mudguards. And talking of guards, there are all the mounts you need for guards and racks, which means this really is a bike you can ride every day of the year. And love it.
A 4 season endurance road bike, Colibri Al 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, Hardnott, the list is endless.
