2009 Campagnolo Zonda Wheelset A classic model in Campagnolo's wheel range Features differentiated rim profiles, 24mm front and 28mm rear, both have been lightened between the spoke holes. This solution gives a steerable front and a very stiff rear Both rims have a top bridge that is free of holes so rim tape is not needed Hubs have oversized aluminum axles and self-aligning bearings Ultra aero stainless steel butted spokes laced radially on the front and the G3 rear pattern G3 spoke pattern results in better transfer of driving torque, lateral rigidity, and reduction of the stress in the rear wheel spokes Includes Campagnolo double-pivot/arm QR skewers, 12t cassette lockring, and wheel bags 1610g set: 675g-front / 935g-rear
