Campagnolo Zonda DB 2025 Wheelset

Zonda™ Disc Brake is a benchmark for all mid-range aluminium Disc Brake wheels.

A completely redesigned structure specific to bicycles with disc brakes.

The result is all-round improved reactivity, especially thanks to the asymmetrical rims and Mega G3™ hubs on both wheels. This innovative solution provides a stable front wheel that is able to absorb energy from the braking torque generated on the left-hand side and a rear wheel that guarantees maximum power transfer from the cyclist.

Compatible with HH12, QR and 135 and 142 rear hubs.

MAIN BENEFITS

Compatibility

• - 6 screws and AFS™ to ensure full compatibility with every disc available on the market.

Reliable

• The front wheel also features G3™ technology for top performance even during very powerful braking.

Affordable performance

• Excellent stiffness and reactivity thanks to the G3 system, the milled rim and the innovative RDB balancing system.

MAIN FEATURES

NEW ASYMMETRIC RIMS PROFILE (26 – 28 mm) MILLED RIM: this machining makes possible to reduce the peripheral weight of the rim and makes the wheel extremely reactive. RDB™ - 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. MOMAG™: allows the external profile of the rim to be free of holes to benefit of both stiffness and weight. SPOKES: G3™ technology applied also to the front wheel to better perform at high braking power. FRONT WHEEL SPOKES: 14 spokes in stainless steel section diameter 2/1,6/2 mm (left side - braking side) 7 spokes in stainless steel section diameter 2/1,6/2 mm (right side). REAR WHEEL SPOKES: 7 spokes in stainless steel section diameter 2/1,6/2 mm (left side - braking side) 14 spokes in stainless steel section diameter 2/1,6/2 mm (right side - cassette side). NIPPLES: black anodized self-locking nipples outside the rim allows for easy maintenance. CUP AND CONE BEARINGS: easy bearing adjustment that reduces possible bearing play, maintaining performances over time and keeping the optimal contact angle between ball and track. NEW ADJUSTING LOCKING WITH MICROSETTING TECH: for an accurate adjustment of the hub that prevents the creation of any play. TWO DIFFERENT INTERFACES WITH THE ROTOR: 6 BOLTS AND AFS™: for allowing the full compatibility with every rotor available in the market. 21 SPOKES IN STAINLESS STEEL WITH MEGA-G3™ SYSTEM: ensures extremely good stiffness and reactivity, reinforcement on braking side at the front and cassette side at the rear. It gives a very race design to the wheelset.
