Bora Ultra WTO 33 Disc Brake Wheelset

Campagnolo Bora Ultra WTO 33 Disc Brake Wheelset

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. Built using Campagnolo’s Hand Made Ultra-Light Carbon (H.U.L.C.), the rims have Campagnolo’s mirror-like Luxury (C-LUX) finish, and undrilled 2-Way Fit rim beds, for perfect tubeless compatibility without rim tape.

Campagnolo’s beautifully moulded carbon fibre front hub body is hourglass shaped to improve aerodynamics, and is securely bonded to a light aluminium hub flange. Integrated radial spoke seats ensure perfect alignment, hidden Aero Mo-Mag nipples and slimmer Aero Elliptical spokes in Campagnolo’s G3 spoke pattern further enhance performance, and its CULT ceramic bearings promise almost frictionless rotation.
