Campagnolo Bora WTO 45 Disc 2-Way Fit Wheelset

The Campagnolo Bora WTO 45 Disc 2-Way Fit Wheelset is the current expression of a lineage that began in 1994, when Campagnolo introduced the original Bora as one of the first production carbon road wheels available to competitive cyclists. Three decades of development, professional peloton use, and Tour de France victories later, the WTO generation represents the most technically complete Bora Campagnolo has built. The WTO name reflects a development process that extended well beyond standard wind tunnel evaluation — Campagnolo built this wheel around the premise that aerodynamic performance needs to translate to real roads, not just controlled laboratory airflow. At 45mm, the depth sits at the most useful point in the range for most road riders: deep enough to deliver real aerodynamic return on sustained efforts and descents, shallow enough to stay predictable in crosswinds and on climbs.

Campagnolo's WTO development tested rim profiles at multiple yaw angles, targeting specifically the 12-degree and 19-degree conditions where real-world crosswinds create most of a wheel's aerodynamic work. Many rim designs are optimized at zero yaw — the condition that produces the cleanest drag figures — but that doesn't reflect how wheels actually perform when wind arrives from the side, which it nearly always does on open roads. The Bora WTO's rim profile performs consistently across the range of angles riders encounter on race courses and everyday training roads. The 45mm depth captures meaningful aerodynamic benefit on the flats without generating the steering torque that makes deeper rims demanding in gusts — a depth chosen because it earns its aero return in conditions that actually exist.

The rim uses Campagnolo's H.U.L.C. carbon construction, which optimizes the fiber-to-resin ratio in the rim walls for maximum stiffness at controlled weight. The surface applies Campagnolo's C-LUX treatment, which eliminates the lacquer coating found on most carbon rims — saving perimeter weight and creating better mechanical contact for tubeless bead seating. Tubeless setup is further simplified by the sealed internal construction: no spoke nipple holes on the rim bed means no rim tape is needed before mounting a tubeless tire. The internal width is 23mm (C23 in Campagnolo's designation), supporting tires from 25mm through 35mm, which keeps the wheel relevant for riders running 28mm or 30mm setups for improved road feel and grip. The 2-Way Fit hooked bead design supports both tubeless and standard clincher configurations — inner tubes remain an option.

The G3 spoke geometry addresses a structural problem inherent in rear wheel design. A rear hub is offset from center to accommodate the cassette, which means conventional even-distribution lacing produces higher tension on the non-drive side and lower on the drive side — an imbalance that reduces lateral stiffness and accelerates spoke fatigue. Campagnolo's G3 system groups spokes in clusters of three, using a 2:1 drive-to-non-drive ratio that distributes tension more evenly across both flanges. Front and rear each run 24 aero-elliptical straight-pull steel spokes, hand-built to specification by Campagnolo specialists with electronic tension verification across every spoke before the wheel ships. The hubs are machined from solid aluminum billet and carry Campagnolo's USB — Ultra Smooth Bearings — a ceramic cup-and-cone system that runs lower friction than standard steel bearings, adjusts to precise tolerances, and is designed for service life that spans multiple seasons of hard riding.

Hub spacing is 12x100mm front and 12x142mm rear with Center Lock disc brake mounts. Three freehub options are available: Campagnolo N3W for current 12-speed and 13-speed Campagnolo groupsets (with an adapter ring that also supports 11-speed cassettes), Shimano HG11 for Shimano and SRAM 11-speed road setups, and SRAM XDR for SRAM's 12-speed AXS groupsets. The wheelset ships with tubeless valves, valve reducer bushings, composite tire levers, AFS disc rotor interface rings, and individual transport bags — everything needed to set up tubeless immediately without additional purchases. The Bora WTO 45 sits between the Scirocco and the Bora Ultra in Campagnolo's disc-brake road lineup: for riders who want Campagnolo's engineering pedigree at a more accessible price point than the Ultra, it's where the substantial majority of the performance lives.
