Campagnolo Shamal C21 DB Wheelset - 28" | Carbon | 2-Way Fit | AFS - 12x100mm | 12x142mm - XDR

The first Campagnolo wheel dedicated to endurance that breaks the mould and looks to the future, carrying with it the strength of the name it has inherited: Shamal.

It will be a fiery summer for the more demanding cyclists seeking to challenge the roads with these new Campagnolo wheels, as hot as the wind that gives them their name. Shamal represents innovation and advanced research since 1992 when with this wheel the company introduced the high-profile rim concept to the world of bicycle racing. This further restyling features an identical approach aimed at improving the cyclist’s performance during the long hours spent in the saddle and at providing comfort and manageability in any conditions.

Note: The version with N3W freewheel is not only suitable for Campagnolo 13-speed drivetrains, but also for the use of Campagnolo 12-, 11- and 10-speed cassettes (from 11 teeth on) thanks to the included adapter kit.

Highlights of Campagnolo Shamal Carbon DB wheels

Specially developed for endurance use

This is the first wheel Campagnolo has dedicated to endurance, with a wider internal rim capable of accommodating bigger tires to make sure that the cyclist enjoys maximum comfort when racing and on longer rides. The rim’s profile, with a 21 mm internal rim width, perfectly couples with 25, 28 and 30 mm tires and makes this wheel the perfect allrounder, even suited for a greater choice of tires that are ideal for varied gravel terrain.

Clincher or Tubeless - you decide!

Thanks to the 2-Way Fit technology, Campagnolo guarantees total compatibility with either clincher or tubeless tires. The use of Campagnolo’s patented MoMag technology ensures there are no holes in the bridge connector which translates into lighter weight, an increase in rigidity and today also easier use of tubeless tires because no rim tape is needed. Tire maintenance and cleaning when changing them has never been simpler.

Precision, smoothness, reliability

Another new feature is the rim’s profile made of unidirectional High Modulus carbon and the differentiated front/rear rim profile height: 40mm at the rear to ensure maximum reactivity and total power transfer, 35mm at the front to ensure the most confident control possible. The rim is unpainted, a fact that highlights the top quality of the craftsmanship and of the materials employed.

The wheel is completed by the new aluminium hubs with a cup-and-cone bearing system that is very light and high performing. This choice offers greater smoothness and allows easy adjustability of the bearings, thereby reducing any play between ball bearings and cones and therefore ensuring extreme functional precision and long-lasting performance. It is also possible to purchase a kit for replacing the bearings by choosing the top-end USB and CULT ranges.

Reliability - a key element in worry-free cycling - is guaranteed by the wheel’s engineering and the G3 spoke lacing pattern, a Campagnolo patented feature that provides well-balanced and safe breaking in any terrain condition.

Technologies of the Campagnolo Shamal Carbon wheelset

2-Way Fit

The 2-Way Fit profile makes it possible to fit both, a tubeless tire or a classic clincher. With 2-Way Fit you are able to test and decide which of the two solutions suits you best or use the clincher for training and the tubeless tire for the race day. With no doubt tubeless tires are the future of road cycling. Apart from greater comfort you can exploit the greater smoothness due to the absence of friction between the tire and the tube when using a tubeless tire. There are no risks of sudden deflation when a tubeless tire is punctured, a great advantage in safety terms. And if the tubeless tire has a puncture the 2-Way Fit system allows you to use a traditional inner tube by simply removing the hermetic closure valve to ride home with no problem.

MoMag - the "mounting magnet" with brains

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! The closed rim well is more stable, with clincher tires no rim tape is needed anymore, which saves weight. The spokes can be tightened more tightly and changed easily, the wheel is stiffer and more stable, reactivity and acceleration capacity higher.

G3 geometry

Campagnolo has developed a spoking pattern that allows improved energy transfer compared to the traditional wheel. The use of double the number of spokes on the right side of the rear wheel reduces the stress on the spokes located there. This gives the G3 amazing advantages, not only increasing lateral stiffness but also reducing spoke tension on the rear wheel and ultimately improving the transmission of power. In addition, the response behaviour is also optimised and vibrations are eliminated at higher system weight.
