Colibri Ti Ultegra Di2

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


Light, fast, responsive and smooth. Really smooth. The Colibri Ti glides up long climbs and it’s a rapid and confident descender. Quick when you want it to be, relaxed and easy to pilot when you want to take it easy.

With Ultegra DI2 you get fast and accurate shifting every time. The shifters and brake levers are an incredibly comfortable place for your hands and you can adjust the bite point of brake levers to get it just how you want it. Paired with the R8070 calipers you get outstanding, reliable braking, perfectly modulated. The new R8050 rear derailler has more accurate chain placement than ever and the smooth gear changes are a perfect match for the Colibri’s titanium ride.
