Colibri Ti 105

We never have and never will share your information with anybody else.


Feel fresher for longer. Colibri's modern performance geometry is tuned in for all-day riding comfort and speed on Britains varied road surfaces. Colibri Ti is for Alpine adventures, fast and stable descents, and year round days in the saddle; the bike for Britains most remote roads, toughest climbs and the bike of choice for epics like the TCR.

There’s nothing quite like titanium, combining the benefits of other materials for a unique and uncompromising ride. Half the weight of steel, twice as strong as aluminium, and more resistant to fatigue and impact than carbon and aluminium. Plus, it doesn’t corrode, making it ideal for a life as a working road bike.

With clearance for up to 36mm tyres or 32mm with mudguards, Colibri Ti is compliant and comfortable: a rewarding ride that eats up billiard-table smooth bitumen.

A 4 season endurance racer, Colibri Ti 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.
