Bora is an intense Adriatic wind that blows in gusts. With Campagnolo's Bora Ultra TT Crankset, you'll ride as if those gusts are always at your back. The spider is made entirely from super-stiff unidirectional carbon fiber, in a solid, wind-cheating shape. The carbon crankarms are hollow and the axle is titanium to keep weight down to a minimum. And with CULT ceramic bearings, you'll roll friction-free for thousands of miles.
