The top of Campagnolo's road wheel range, rebuilt around the wider C23 rim. The Bora Ultra WTO 45 C23 pairs a 45 mm hand-made carbon rim with a carbon front hub and CULT ceramic bearings; Campagnolo calls it the best choice for all-round riders, balancing speed, agility and stability.

Highlights

  • 45 mm H.U.L.C. carbon rims, C-LUX finish
  • C23 rim: 23 mm internal, 28–35 mm tyres
  • 2-Way Fit: tubeless, tubeless-ready or clincher
  • Carbon front hub body, CULT ceramic bearings
  • 21 G3 Aero Elliptical spokes, internal Aero Mo-Mag nipples
  • Claimed 1,325 g the pair

Rims

The drop-shaped C23 rim is 23 mm wide inside and 28.4 mm outside, shaped for smooth airflow and able to take tyres from 28 to 35 mm. It's made with Campagnolo's Hand Made Ultra-Light Carbon (H.U.L.C.) process, with a new lay-up that routes fibres around the spoke holes rather than punching through them. The C-LUX finish needs no lacquer, saving weight and helping tubeless beads seat cleanly.

Hubs and spokes

The front hub has a carbon body; both hubs run on CULT ceramic cup-and-cone bearings. Each wheel uses 21 straight-pull, double-butted 1.5 mm Aero Elliptical spokes in the G3 pattern with self-locking aluminium Aero Mo-Mag nipples hidden inside the rim, so the rim bed stays undrilled and tubeless needs no tape. Each wheel is hand-assembled and checked by a Campagnolo technician.

Options

OptionFreehub body
N3WCampagnolo N3W body, for Campagnolo 11-, 12- and 13-speed cassettes
HGShimano HG11 body, for Shimano HG-spline road cassettes
XDRSRAM XDR body, for SRAM XDR road cassettes

Compatibility & fit

Disc brake with AFS rotor interface and 12 mm aluminium thru-axles, 100 mm front and 142 mm rear. Choose the freehub body that matches your cassette. N3W takes Campagnolo cassettes that start with a 9 or 10-tooth sprocket (such as Ekar and Super Record Wireless) directly; cassettes that start with 11 or 12 teeth need Campagnolo's N3W adapter. Cassette fitting and tubeless set-up are separate workshop services at Tune Cycles.

Campagnolo guarantees its products for three years from the date of purchase against defects in materials and workmanship; proof of purchase is required. The warranty doesn't cover crash damage, normal wear and tear, incorrect installation, use with non-compatible parts, or consumables such as tyres and rim tape. For warranty support, return the product to Tune Cycles and we'll manage the claim with Campagnolo's Australian distributor.
