Campagnolo's Bora and Shamal wheels are icons of Italian cycling engineering. Our ceramic bearing kit brings them into the modern performance era with Grade 3 silicon nitride bearings and DLC-coated races. The USB hub system's legendary smoothness gets even smoother — less friction at the bearings means more speed on the road. Compatible with Bora WTO, Bora Ultra, and Shamal platforms.
