Campagnolo Shamal Ultra C17 Clincher Wheelset

The Shamal Ultra has always been a benchmark among the best aluminium wheels on the market.

The Shamal Ultra has a wider profile, further improving two very important aspects that have made this wheel the leading product that it is: reactivity and manageability. the wider profile combined with Campagnolo know-how, has led to a 3% improvement in terms of reactivity and 5% in terms of manageability.

These exceptionally lightweight wheels offer cyclists a unique riding experience that's all about speed, responsiveness and extremely smooth rollability.

The Best - Always

• USB bearings give Shamal Ultra wheels exceptional smoothness
• The carbon hub bodies considerably reduce the weight of the wheels and enhance performance thanks to a high degree of lateral stiffness, keeping overall weight to a minimum
• The distinctive G3 spoke lacing pattern ensures supreme power transfer, simultaneously reducing strain

Long-Lasting Performance Guaranteed

• The aerodynamic aluminium spokes, the self-locking nipples and spoke anti-rotation system have been developed to guarantee the wheel's maximum performance over time
• The differentiated rim height and hub diameter make the Shamal Ultra an extremely lightweight wheel without compromising on performance

Suits All Needs And Tastes

• The version for clinchers guarantees ease of use and offers a convenient solution in case of puncture
• The 2-Way Fit version is designed for those who prefer tubeless tyres offering smoother rolling and bolder racing features

Technology

USB Ultra Smooth Bearings

Perfectly smooth surfaces and lower friction to reduce loss of power are the most interesting features.

Add on the reduced weight and resistance to corrosion and you will understand why Campagnolo can give you the best thanks to USB. All your power will be transferred onto the road.

Campagnolo has a long-standing reputation for the extremely high performance of its hubs in terms of smoothness and reliability. In fact, all the projects are entirely developed in our R&D department Campy Tech Lab and Campagnolo have put obsessive care into taking care of every detail.

The hubs with USB ceramic bearings (Ultra Smooth Bearings) further enhance the wheels' smoothness and reduce weight and the need for maintenance. Comparative tests have shown that USB bearings are 50% smoother than standard bearings.

Now improving your performance during the race or simply going for a ride with your friends will be easier.

USB - Ultra Smooth Bearings - technology is used for Record cranksets and for the new Shamal Ultra wheels.

2-Way Fit

2-Way Fit is the profile which makes it possible to fit both a tubeless tire or a classic clincher.

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.
