Campagnolo Bora Ultra WTO 45 2WF C23 Disc Wheelset

Campagnolo has been making components and wheels in Vicenza, Italy since 1933, and the Campagnolo Bora Ultra WTO 45 2WF C23 Disc Wheelset represents the current pinnacle of what the brand has developed at the top of pro road racing. The Bora Ultra sits at Campagnolo's highest tier, and the WTO 45 is the all-around version of that wheel: deep enough at 45mm to be genuinely fast on flat and rolling roads, light enough at 1,325g claimed for the pair to not cost you on climbs, and stable enough to be reliable in real-world wind rather than just in favorable test environments. WTO stands for Wind Tunnel Optimised — the rim profile, spoke geometry, and overall architecture were developed with aerodynamics as an explicit engineering objective, not a secondary consideration. The 45 sits in the middle of the Bora Ultra WTO depth range (35, 45, and 60mm options), and it's the depth that works across the broadest range of terrain without demanding course-specific decisions.

The rims are built using Campagnolo's H.U.L.C. (Handmade Ultra-Light Carbon) process — a manufacturing technique that optimizes the ratio of carbon fiber to proprietary resin throughout the rim structure to maximize stiffness and control while eliminating unnecessary material. The rim is 45mm deep, constructed from UD high-strength carbon fiber with a 23mm internal width and 28.4mm external width, shaped with a drop-section profile developed to reduce aerodynamic drag as a whole system rather than optimizing only the leading edge. The C-LUX finish — high-gloss and lacquer-free — keeps weight low while maintaining the clean look the Bora is known for. 21 Aero Elliptical straight-pull double-butted spokes lace in Campagnolo's G3 geometry — groups of three parallel spokes in a 2:1 arrangement that distributes load differently from conventional even-count lacing. Aluminium Aero Mo-Mag nipples lock completely inside the rim cavity, hidden from airflow and protected from road contamination, while also allowing the rim wall to be built lighter at the nipple seat than a conventional external nipple design permits.

The front hub features an aerodynamic carbon shell — an uncommon specification on production disc wheels at any price — housing Campagnolo's CULT (Ceramic Ultimate Level Technology) bearings in a cup-and-cone configuration. CULT bearings are produced to Campagnolo's own design and specification, with ceramic balls that deliver extremely low rolling friction and require less pedaling energy to maintain speed. The cup-and-cone design allows precise preload adjustment, a serviceability advantage over cartridge bearings that can't be tuned without replacement. The rear hub runs the same CULT ceramic bearings inside Campagnolo's N3W freehub body — the patented Next 3 Ways standard, engineered to house 11-, 12-, and 13-speed cassettes with 9-, 10-, or 11-tooth starting sprockets while retaining compatibility with older 9- and 10-speed cassettes. Both wheels run 12mm thru axles (100mm front / 142mm rear) with AFS center-lock disc interface. Three freehub options are available at purchase: Campagnolo N3W, HG11 (Shimano and SRAM 11-speed), or XDR Driver (SRAM AXS 12-speed).

The 2-Way Fit rim construction allows the Bora Ultra WTO 45 to run tubeless without rim tape — the rim bed is sealed at the factory and tubeless valves are included in the box. Campagnolo recommends 700c tires from 28 to 35mm, which reflects both the C23 internal width and the design intent of a modern road racing wheel. The wider rim supports lower pressures for better grip and compliance without sacrificing rolling efficiency, and it improves the aerodynamic relationship between rim and tire by allowing the tire to fill the rim profile more completely. Every Bora Ultra WTO 45 is hand-assembled by a dedicated Campagnolo technician and verified against electronic tolerances before it ships — a genuine production standard, not a marketing claim, at this tier of the market.

Each wheelset includes the Aero Mo-Mag nipple maintenance kit, tubeless valves, AFS center-lock lockrings, Campagnolo wheel bags, accessories bag, tyre levers, and a Campagnolo N3W Z11 adapter on N3W freehub versions. The Bora Ultra WTO 45 is the right wheel when the course doesn't allow you to specialize — when you need speed on the flats, minimal penalty on the climbs, and a wheel that handles real wind without becoming a management problem. Campagnolo has been building wheels that win at the highest levels of professional road racing for decades, and the Bora Ultra WTO 45 is what that lineage looks like configured for the all-around rider rather than a single race profile.
