Campagnolo BORA Ultra WTO 33 Disc Brake 2WF DCS Front Wheel

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

Optimised for Speed

Climbers will love the Bora Ultra WTO 33’s lower weight, helping them to reach heights even faster, change pace instantly, and descend with speed and confidence. 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 CULT ceramic bearings promise almost frictionless rotation, and keep your hubs spinning for 5 ½ times longer than standard steel bearings. The aluminium rear with 36-tooth ratchet system can be driven by N3W, XDR or HG freehub bodies.

Hand-Crafted Carbon

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 - no need for rim tape here. The Bora™ Ultra WTO™ 33 Disc Brake wheel is entirely hand-assembled by a specialised Campagnolo® technician and is 100% checked by electronic instrumentation. This procedure ensures that every single Campagnolo® wheel offers maximum performance and reliability every single time.

Wider and Faster

The completely redesigned Bora Ultra WTO 33 rim now has a 21mm internal width, and is compatible with tyres from 25mm, aerodynamically optimised for this starting compatible tyre dimension. The Bora Ultra WTO 33 2-Way Fit rim meets ETRTO tubeless standard for fast-rolling tubeless tyre fitment, and is also suitable for tubeless-ready and clincher tyres too. Wider tyres on wider rims create greater air volume and better sidewall support, and especially when tubeless, can confidently be used at reduced pressures, improving grip, control and comfort, and lessening fatigue without affecting speed.

Aerodynamic Details

The hub bodies of these wheels are slimmer in the centre to reduce the frontal area they present to the wind. The 24 double-butted Aero Elliptical spokes in each wheel have reduced from 1.6mm to 1.5mm in diameter. New Aero Mo-Mag nipples are hidden inside the rim to clean up the airflow over them and are still easily adjustable. 

All of the new Bora Ultra WTO wheels are designed for AFS (centerlock compatible) disc rotors. Campagnolo’s unique G3 spoke system counteracts the main source of torque at each hub, while CULT ceramic bearings keep the Bora Ultra WTO hubs spinning freely for 5 ½ times longer than standard steel bearings.

Perfect Alignment

Campagnolo moulds the nipple and valve holes into the rims, so no carbon fibres are cut by drilling. Each spoke hole has an internal nipple seat, wrapped into the rim’s carbon layup, which is specifically aligned to the intended hub. Aero Mo-Mag nipples are perfectly aligned with each spoke for a more accurate wheel build, with reduced localised stress and improved fatigue life.
