• 2-Way Fit: tubeless without rim tape, or clincher

• 1240 g per wheelset (Campagnolo figure)

Rim

The 37 mm carbon rim is moulded with Campagnolo's H.U.L.C. process and finished in lacquer-free C-LUX, which also helps tubeless beads seat and seal. Aero Mo-Mag nipple seats leave the rim bed free of spoke holes, so the 2-Way Fit rim runs tubeless without tape, and the single-joint rim construction adds stiffness. The rear rim is asymmetric for balanced spoke tension.

Hubs and build

The black aluminium monolithic hubs use Campagnolo's Head-2-Bay system for precise spoke head seating and even tension, and run CULT ceramic bearings. 21 round-section slim steel spokes at the front and 24 at the rear are laced two-cross. Each wheel is hand-assembled by a Campagnolo technician and checked electronically. Campagnolo quotes 1240 g for the wheelset.

In the box
