Campagnolo Bora Ultra WTO 33 Disc Wheelset

Not Enough Available

At only 33mm deep, the Bora Ultra WTO 33 has the shallowest wind tunnel optimised (WTO) rim profile of the new Ultra family. Every external component of the wheel has been redesigned to maximise aerodynamic efficiency and reduce weight, saving you precious energy, and generating greater speed from the same rider input.

Climbers will love the Bora Ultra WTO 33’s lower weight, helping them to reach the heights even faster, change pace instantly, and descend with great speed and confidence.

The Bora Ultra is Campagnolo's flagship range of disc-specific wheels feature a new carbon design to reduce weight, a lacquer-free finish, updated hubs and a clever new spoke arrangement with the nipples fully hidden inside the rim. All that results in wheels that are lighter, stiffer and more aerodynamic.

The latest Bora Ultra WTO line-up features 33mm, 45mm and 60mm rim depths. The 45mm and 60mm-deep wheels have a 19mm internal rim, while the 33mm-deep rim is 21mm-wide. Campagnolo have optimised the wheels for use with 25mm tyres.

The rim bed is undrilled no need for tape and compatible with clincher, tubeless-ready and tubeless tyres. However, the rim retains a traditional hook i.e. it’s not hookless, as has been the trend for recent tubeless wheel launches.
