Campagnolo Zonda C17 Disc Clincher Rear Wheel

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

Massima compatibilità

• 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

Technology

MoMag

What is 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.

How does it work?

The nipples, once inserted inside the rim via the valve hole, are “guided” to the point of connection with the spoke by means of the magnet.

This simple but ingenious system makes it possible to have a wheel without holes on the upper bridge, but with spokes tensioned by traditional nipples!

Advantages:

No holes on the rim means that the rim is uniform at every point, free from stress points or zones of weakness and, for the clincher profiles no rim tape is required, to the benefi t of weight reduction. The advantages are immediately clear: greater rim lifetime, greater resistance to fatigue, the possibility to give the spokes greater tension, and greater stiffness which, in terms of performance, mean greater reactivity and acceleration.

But that’s not all. The advantages also include extremely quick and simple maintenance and spoke replacement. All to the benefit of cyclists who choose Campagnolo.

Campagnolo Wheel Identification Card

Since its birth over 80 years ago Campagnolo has been dedicated to continuous innovation in order to produce the best, most competitive and reliable products possible. To continually push the limits in this way is the work of the engineers of the Campy Tech Lab. Even the smallest details and material choices are painstakingly scrutinized in an effort to produce what is often to become the newest performance standard. As a result, our testing department is one of the most important areas of the entire operation and each and every product must go through strenuous and extreme testing before it earns the right to bear the Campagnolo name. Campagnolo test at levels above and beyond anything required and as a result produce products that are a step ahead.

• Fatigue test: before the manufacturing stage, each wheel and each of its components are subjected to long and very challenging tests that ensure the durability and performance over time.
• Crash test: simulates the impact of the wheel in differing situations. Campagnolo crash tests have successfully passed all requirements stipulated by the UCI.
• Tyre burst test: all Campagnolo wheels are tested at inflation pressures well above those indicated on the tyre.
• Environment test: exposure to UVA and UVB rays, salt attack and exposure to moisture: these are the tests that all Campagnolo wheels must pass to ensure maximum performance and reliability over time.

100% Manually assembled and Electronically checked.

The extensive attention to detail and testing mentioned above may be sufficient for some companies to ensure the quality of their product but not for Campagnolo. To ensure the quality of each and every wheel the standards applied to the production process must be then verified on each and every final product at the end of fabrication. Campagnolo made a clear and bold decision: to assemble each wheel manually and submit it to a series of final inspections that guarantee their quality.

Only through in-depth inspection, both manual and digital, of each and every piece of every final product that leaves the premises can Campagnolo be 100% sure of the exact same quality for each and every wheel that bears the Campagnolo name.

• Balancing: guarantees the absence of vibrations at fast speed.
• Lateral and radial control: guarantees the perfect alignment of the wheel to ensure precise rolling of the wheel.
• Camber: ensures the perfect symmetry of the wheels with the bicycle.
• Spokes tension: ensures optimal balance at every point of the wheel.
• Rolling torque of the hub: ensures a perfect adjustment of the hubs.

Features

New Asymmetric Rims Profile (26–28mm) 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.

Rear Spoke Wheels

• 7 spokes in stainless steel section diameter 2/1,6/2mm (left side - braking side)
• 14 spokes in stainless steel section diameter 2/1,6/2mm (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 Bolt 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.
