🌍New 2024 Campagnolo Bora Ultra WTO🌍

Campagnolo has announced a revamped line-up of its Bora WTO and Bora Ultra WTO wheelsets, with both options featuring a wider 23mm internal rim width.

The main unifier in the Bora WTO and Ultra WTO range is the new C23 carbon rim shape, which has a 23mm internal rim width. The carbon construction differs between both ranges, with Campagnolo claiming the Ultra WTO rims weigh 420g per set, and the WTO rims 550g. 

Campagnolo says wider rims “guarantee a larger [tyre] surface in contact with the ground that benefits aerodynamics and trajectory control”.

Many wheel brands now claim a wider rim offers a more rounded tyre shape, which improves handling and smooths the transition between the tyre sidewalls and the rim. The latter, it’s often claimed, confers a small aerodynamic benefit.
