The Shamal Dual Profile. Engineered for cyclists who demand versatility and high performance. Comfortable over a long distance, capable on all terrains and excels in all wind conditions. The Shamal's have a new revolutionary characteristic in the wheel design called Dual Profile, first developed with CFD (Computational Fluid Dynamics) analyses and later perfected in the wind tunnel and during road tests, until the conclusion of the process that involved the final shaping of carbon. A different modular profile that, combined with hubs with differentiated flanges ensures the use of shorter spokes, to the advantage of overall rigidity without forgoing comfort for the rider when pedalling. The smoothness of the Shamal wheels has been entrusted to their aluminium hubs built according to the cup and cone system, which allows for easy maintenance of the bearings. Compared to the previous model, the adoption of new materials ensures a weight reduction of over one hundred grams, thus reaching a total weight of 1480g. Dual Profile Design Tested in the wind tunnel and proven on the road. An unprecedented double-height profile 45/40mm with a differentiated line to improve aerodynamics in crosswind conditions. Straightforward benefits in terms of bike handling and rideability in all conditions. C-LUX Finish C-LUX is an evolution of the already premium finish of Campagnolo carbon rims. Their high gloss, mirror-like surface is not only high-quality, but is so flawlessly smooth that it doesn't require lacquer, saving weight. The scientific precision of C-LUX also helps to ensure the safest possible seating of tubeless tyres, increasing the pressure seal, ease of installation/uninstallation, and reducing the risk of abrasions to the bead. 2-Way Fit Campagnolo's 2-way fit technology allows you to customise your ride - opt for a clincher during training sessions or switch to tubeless for race day. Embracing tubeless tyres ensures a smooth ride with increased comfort and safety. The 2-Way Fit system enables a hassle-free switch to classic tubes in case of a puncture, keeping you riding without interruption. C23 Rims Through extensive research, Campagnolo determined that their C23 rims are the perfect choice for riders aiming to improve their aerodynamics and control. The 'teardrop' shape of the rims ensure the smoothest flow of air during the ride and can fit both wide gravel tyres and thinner road tyres.
