Campagnolo Shamal Ultra C17 2-Way Fit Rear WheelThe new Shamal Ultra C17 2-Way Fit Rear Wheel continues the legendary performance this model has held for over 20 years. It's the first top for many top-end competitive cyclists in all areas of the sport. This version pushes performance further thanks to the increase in design and technology Campagnolo is known for, which includes the perfect integration of being Tubeless Compatible. The tubeless setup makes the wheel inertia and rolling resistance much lower while increasing grip and traction significantly; this is the future of road racing.Optimised Rim ProfileThis version of the Shamal Ultra features the new C17 rim profile to ensure a better rim to tyre interface, which in turn improves performance. This performance boost is especially noticeable when using 25 and 28c road tyres - the modern standard. To maintain this wheel exceptional reactivity and momentum it has been equipped with USB Ceramic, sealed cartridge bearing, which although reducing weight, also greatly improve rolling performance and smoothness. Ceramic ball bearings have a high corrosion resistance, meaning wheel maintenance is rarely required.Podium Proven PerformanceThis wheel features the Campagnolo iconic, performance enhancing Mega-G3 spoke lacing pattern. This spoke pattern improves energy between the rider and the road, which reduces stresses on the drive side (right side) of the wheel while increasing the rigidity of the wheel overall at the same time. This significant performance enhancement is achieved by the drive side of the rear wheels having twice as many spokes as the non-drive side (left side).Hand Built and Fine-TunedCampagnolo wheels are hand built entirely by specialist Campagnolo wheel builders and are fine-tuned and checked precisely with electronic tools. The ensures that every wheel delivers the high-performance output that Campagnolo wheels are known for.Features: Material: Rim: Aluminium; Hub: Carbon, Aluminium Rim Internal Width: 17mm Rim External Width: 22mm Rim Profile: Differentiated, 27/30mm Hub Spacing: 130mm Spoke Count: 21 Spoke Lacing: G3 Bearings: USB, Cup and ConeBuy Campagnolo Wheels & Tyres from Chain Reaction Cycles.

Campagnolo Shamal Mille C17 Road Clincher WheelsetCampagnolo's Shamal Mille C17 Road Clincher Wheelset represents the premium standard in performance aluminium racing wheels. The chic surface treatment that gives this wheelset its smooth and smart dark look also represents a major performance improvement. This treatment allows sure-footed and sturdy braking power over and above normal aluminium rims, regardless of weather conditions.Enhanced PerformanceThe C17 rim ensures a better rim/tyre connection and an enhanced performance, especially when using 25mm and 28mm tyres. This stylish wheelset gets an upgrade by way of black anodised nipples to complete its minimalist dark look. The Shamal Mille is certain to have heads turning by both the competition on race day and those beside you at traffic lights.Features:Plasma Electrolytic Oxidation: It offers an elegant finish and enhances braking power and modularityToroidal Milling Spiral Groove on the Braking Track: Reduces braking distance while maintaining silent braking Differentiated Rim Height: Front (24mm - 27 mm) and rear (27mm - 30 mm)Dynamic Balance™MoMag: Allows the external profile of the rim to be free of holesAerodynamic Spokes in Aluminium: Maximum air penetration, less weight and greater reactivityDifferentiated Spokes: 16 radial spokes for the front, 21 spokes for the rear, doubled on the right and exclusive Mega-G3 spokes to reduce vibration, increase stiffness and transmission of power to the wheelBlack Nipples: Black oxidation finishing self-locking aluminium nipples outside the rim. Allows easy maintenance and less truing over the wheel lifetimeSpokes Anti-Rotation System: It keeps the spokes in position of maximum aerodynamicsCeramic USB Bearings with Differentiated Diameters: 28mm for the front, 30mm for the rear. Less friction, less weight, greater smoothness and the same performance over timeHub Body in Carbon: High lateral stiffness, reducing weight to a minimumAxle in Aluminium: Low weight, high stiffnessOversized Flange: It increases torsional stiffness, increasing its reactivity at every change in the cyclist's paceWeight: 1.459kgTechnologies:USB™ - Ultra Smooth Bearings: Hubs with USB ceramic 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.G3 Geometry: Campagnolo has developed an assembly architecture which, compared with a traditional wheel, makes it possible to improve energy transfer, reduce the stress on the spokes on the right and increase transverse rigidity. This is achieved because in G3 geometry the right-hand side of the rear wheel is fitted with twice as many spokes as the left.The results of the G3 system are truly extraordinary: better transfer of the driving torque, better lateral rigidity, and reduction of the stress in the rear wheel spokes. Thanks to the G3 system that compensates for the forces acting on the 2 sides of the wheel, there are no more wheel vibrations, even for heavier people.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.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.Buy Campagnolo Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.
