Campagnolo Zonda C17 Clincher Rear Wheel

The features of the Zonda wheel have been enhanced even further with a C17 rim that is compatible with more comfortable clincher tyres. It's also 10g lighter than the previous version.

Zonda is one of Campagnolo's best-selling aluminium wheels. It's packed with technological innovations that make it a highly sophisticated solution compared to what other brands offer for the same price.

A smaller hub diameter combined with the differentiated rim height (24/27mm) and the new self-locking nipples offer a front wheel that's smooth to steer and bump-resistant: racing on this model is a safe bet.

Main Benefits

Unrivalled

• One of the best-selling wheels of all time, the Zonda is an aluminium tyre boasting technologies that are far more sophisticated than any other product of its kind, within this price range, on the market

All Campagnolo's technology has gone into these wheels

• Weight and stiffness are optimised thanks to the milled rim with differentiated height
• Aerodynamic spokes and self-locking nipples guarantee performance and reliability

Suited to all conditions

• The lightweight structure and hi-tech features of these wheels make them ideal for racing or grand fondo cycling
• The robustness and reliability that set the Zonda apart make it one of the best wheels for road cycling

Technology

G3 Geometry

Campagnolo’s unique G3 spoke pattern comprises groups of three parallel straight-pull spokes, arranged in a 2:1 ratio. Having twice as many spokes on one side allows wheels with G3 to counteract the asymmetric drivetrain and braking forces acting on them, creating more symmetric performance and equalising the load. Energy transfer and lateral rigidity are improved, and spoke tension is optimised, reducing stress and increasing lifespan.

All Campagnolo disc brake wheels utilise the G3 pattern, the front wheel has more spokes on the disc brake side, and the rear is biased to the drivetrain side.

Dynamic Balance

RIM Dynamic Balance – aluminium wheels

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.

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

MoMag

Allows the external profile of the rim to be free of holes – increases structural resistance – makes rim tape unnecessary and reduces the weight of the wheel.

Milled Rim Differentiated Rim Height Rear (27 - 30mm)

Dynamic Balance

Spokes Anti-rotation System

Keeps the spokes in the position of maximum aerodynamic penetration.

Exclusive Mega G3 Spoke Pattern

Perfect balance of spoke tension on both sides of the wheel. Reduces stress, increases transversal rigidity and the transmission of power to the wheel. Mega-G3 eliminates vibrations even with “heavy” cyclists.

Spokes With Aerodynamic Profile

• Rear: 21 spoke variable profile Aero in stainless steel with doubling on the cassette side

Self-locking Nipples

Allow the ideal spoke tension to be maintained at length, eliminating friction on the rim. All this translates into constant high performance throughout the life of the product.

Rear Hub With Mega G3 Oversized Flange

Increases the torsional stiffness, increasing reactivity at each change of pace of the cyclist.

Aluminium Hub Body

Provides a high degree of lateral stiffness.

Aluminium Axle

Low weight, high stiffness.

Differentiated Hub Diameter Front And Rear

Optimised for structural integrity and performance. Small front hub aids in aerodynamic efficiency.

New Adjusting Lock Ring With Microsetting

For an accurate adjustment of the hub that prevents the creation of play.
