Campagnolo Bora Ultra WTO 35 2WF C23 Disc Wheelset

Campagnolo has been building road wheels since the earliest days of professional cycling, and the Campagnolo Bora Ultra WTO 35 2WF C23 Disc Wheelset represents the current top of that lineage. WTO stands for Wind Tunnel Optimized, and the 35mm depth is the shallowest of the three Bora Ultra WTO profiles — positioned as the go-to choice for climbers, riders in variable wind conditions, and anyone who wants the Bora Ultra's engineering without the additional rotational mass of a deeper rim. At 1,285 grams for the pair, the 35 is lighter than the 45mm and 60mm versions while sharing the same construction processes and technologies that define the entire generation.

The rim itself is built using H.U.L.C. — Handmade Ultra-Light Carbon — Campagnolo's process for optimizing the ratio of carbon fiber to resin across the rim structure. The result is a lighter rim without compromising torsional stiffness, which matters most when out-of-the-saddle efforts load the rear wheel or when hard braking loads the front. The profile uses what Campagnolo describes as a "drop-shape" design, taking inspiration from aerodynamically efficient forms in nature to reduce drag across the full range of yaw angles riders encounter on real roads. The C-LUX lacquer-free finish keeps additional weight off the rim while maintaining a clean surface for the decal application. Internal rim width is 23mm — the "C23" designation — and external width is 28.4mm, setting up comfortably for tire sizes from 28mm to 35mm with the 2-Way Fit interface that accommodates both tubeless and clincher setups.

The spoke lacing is Campagnolo's G3 pattern, which groups three parallel straight-pull spokes in a 2:1 ratio rather than the conventional alternating arrangement. G3 has been a Bora signature for years, and its purpose is consistent: maximizing lateral stiffness and cornering precision through tension distribution, while creating the visual identity that makes a Bora immediately recognizable in a peloton. The spokes themselves are 21-count Aero Elliptical, double-butted at 1.5mm, straight pull. Nipples are aluminium Aero Mo-Mag units — fully internal, self-locking, seated inside the rim to stay completely out of the airflow. The internal nipple system improves aerodynamics compared to external nipple designs and reduces the spoke-and-nipple assembly's contribution to turbulence on each rotation.

Bearings are CULT — Ceramic Ultimate Level Technology — Campagnolo's top-tier ceramic bearing specification. CULT uses ceramic ball bearings produced to Campagnolo's own specifications, optimized for extremely low rolling resistance. The hub shell up front uses a carbon body, contributing to the overall weight figure. The rear hub runs N3W — Next 3 Ways — Campagnolo's patented freewheel body standard engineered to accept 11-, 12-, and 13-speed cassettes with 9-, 10-, or 11-tooth starting sprockets. N3W also maintains backward compatibility with older Campagnolo 9- and 10-speed cassettes, and the wheels are offered at RA Cycles in three freehub configurations: Campagnolo N3W, HG11 for Shimano and SRAM 11-speed, and XDR Driver for SRAM 12-speed AXS. Hub spacing is 100mm front and 142mm rear with 12mm aluminium thru axles and AFS disc brake interface.

Each Bora Ultra WTO 35 wheelset is hand-assembled by a specialized Campagnolo technician at the company's Vicenza facility and put through 100% electronic quality inspection before leaving the factory. The set ships with Aero Mo-Mag nipple maintenance kit, tubeless valves, AFS lockrings, Campagnolo wheel bags, accessories bag, tyre levers, and a N3W Z11 adapter for Campagnolo freehub versions. For riders who prioritize weight and all-condition versatility over raw aerodynamic depth — criteriums, alpine stages, sportives with significant climbing, or builds where a versatile single wheelset has to do everything — the Bora Ultra WTO 35 lands at the intersection of every technology Campagnolo currently makes available in a road racing wheel.
