The wider C17 rim design of the Zonda ensures a more efficient shape of the tyre, improving cornering grip and safety while reducing aerodynamic drag and rolling resistance. A seemingly small increase in width offers a surprisingly different riding experience, one that is sure to leave any cyclist convinced that a wider tyre size is the way forward.The asymmetric rim profile offers superior aerodynamics without sacrificing stability, the precision milling eliminates excess material reducing weight, the Rim Dynamic Balance Technology ensures that every point of the rim is counter-balanced by an equal weight on the opposing side, providing maximum stability even at high speeds and the MoMag Technology creates a tyre bed free of spoke holes, eliminating the need for rim tape and offering structural superiority. The wheels are laced with 21 stainless steel spokes in the MEGA G3 Pattern providing reinforcement on the braking side at the front, and the cassette side at the rear; creating the perfect balance of spoke tensions on both sides of the wheel, reducing stress, increasing traversal rigidity and improving the transmission of power to the wheel.

Campagnolo Zonda C17 Road Clincher Wheelset With a redesigned rim that takes its inspiration from a growing trend towards wider tyres, the Zonda C17 model is a truly modern, high performing alloy wheelset. In addition to the wider rim profile, there are differentiated front and rear rim heights, bringing you the ideal balance of comfort and performance.Optimised Aluminium RimThe wider C17 rim ensures a more efficient shape of the tyre, improving cornering grip and safety while reducing aerodynamic drag and rolling resistance. The new C17 rim has been structurally optimised to provide a surefooted grip on clincher tyres as well as an even better braking feel when compared with previous versions. The freehub spins silently as you enjoy time in the saddle.Features: Material: Aluminium (Rim) Brake Type: Rim brake Tyre Compatibility: Clincher Front Hub: 16 Aerodynamic radial spokes Rear Hub: 21 Aerodynamic radial spokes Weight Limit: 109kg Tubeless Compatible: No Axle Type: Quick release Differentiated Rim Height Precision milling to eliminate excess material and weight where not needed Aluminium oversize flange MEGA G3 pattern Cup and cone bearings Self-locking nipples Included: Wheelset, rim tape, QR skewers Weight: 1,540g Technologies:Rim Dynamic Balance: The concept is simple and elegant: balance the weight of the gasket, with an item of similar weight placed on the exact opposite side. For top models, this is obtained by a special operation on the section of the rim opposite the rim joint.Spoked Dynamic Balance: For entry-level models, Dynamic Balance is obtained by using two oversized spokes in the section opposite the joint. The result is a wheel with perfectly balanced rotational dynamics.MoMag: A technology that offers several advantages to the structural integrity of the wheel as well as eliminating the need for rim tape. The name derives from “Mounting Magnet” system, shortened to MoMag.Buy Campagnolo Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.
