The new Shamal Ultra C17 represents the same fantastic performance that has made it THE go-to aluminium race wheel for the better part of two decades while adding even more versatility and performance. The new, wider profile means the C17 standard is perfect for use with the increasingly popular 25/28mm tyre sizes. USB Bearings are ceramic which vastly reduces the weight and greatly improves the smoothness of the bearings. The ceramic ball bearings inside also mean that maintenance will be far less common and it has a much higher resistance to corrosion than standard bearings. The Mega-G3 Spoke pattern is a type of spoke assembly that improves energy transfer between the hub, which reduces stress on the right-hand side which in turn increases the rigidity of the wheel. This is achieved by having twice as many spokes as the left-hand side. The new C17 also allows for a more sure-footed grip in addition to increased comfort while increasing rigidity and thus reactivity at the same time thanks to its wider stance and optimized material usage. Features: Toroidal Milling reduces the peripheral weight of the rim for great reactivity Dynamic Balance where every point of the rim is counterbalanced by an equal weight on the opposite side Ultra-Fit for easy tyre mounting and improved performance for clincher tyres MOMAG: the external rim profile is free of holes, so the structural integrity of the wheel is increased and there is no need for rim tape Differentiated rim height, 27mm front & 30mm rear for optimized structural integrity and performance Carbon hub with USB bearings, aluminium axle Aerodynamic aluminium spokes with exclusive Mega-G3 spoke pattern Weight: 1449g Tech Specs: Spokes Spoke Count: 16 Front and 21 (G3) Rear RDB - Rim Dynamic Balance Aerodynamic Double-Butted Aluminium spokes Ultraliner / DRSC Geometry Self-Locking Aluminium nipples Rims Profile Height: Differentiated (24/27mm at the front - 27/30mm at the rear Material: Aluminium Rim Section: (Height/width): differentiated/22mm Tyre fitment - Clincher with inner tubes Hubs Carbon and aluminium hub USB bearings Width: 100mm (Front) / 130mm (Rear) Oversize flange Cup-and-cone bearing system Freehub: CA 9/10/11/12x, SH 11x or 9/10x with spacers In The Box: New, re-designed quick-release skewers User Manual Warranty Booklet Campagnolo Wheel Identification Card

Born as the very first complete wheelset with each component in its build being specifically designed as a complete unit to ensure unparalleled efficiency and performance the Shamal continued to introduce new technologies that would change the way aluminum performance wheels were produced. So advanced was the Shamal in its early stages that it was found also in World Tour competition often and to this day is still perhaps the most race ready aluminum wheelset available.
Campagnolo Shamal Ultra C17 Wheelset (2 Way Fit)Twenty years ago, this wheelset from Campagnolo was designed to be the first complete wheelset. Still going strong, it offers unrivalled performance and quality. The new Shamal C17 was developed specifically to increase compatibility with 25 and 28mm tyres that are becoming increasingly popular due to their improved aerodynamics and reduced rolling resistance.The new C17 also allows for a more surefooted grip on the road in addition to increased comfort while increasing rigidity and thus reactivity at the same time thanks to its wider stance and optimised material usage.They feature a carbon fibre hub body with extra smooth USB bearings to make them as efficient as possible. The hubs for this newly designed wheel are differentiated between front and rear in order to optimise weight savings while considering structural and performance necessities that change with the individual roles of the two wheels. The 16 aerodynamic anodised aluminium spokes on the front wheel are laced radially while the 21 spokes of the rear wheel are grouped in the Mega G3 pattern, famous not only for its fantastic performance but also for its innovative design.A new adjusting lock ring with micro setting has trickled down to this new C17 version from the Bora family, further highlighting the Shamal’s status as a top tier race wheel.The 2-way fit system allows you to fit either a tubeless tyre or a classic clincher for maximum adaptability.What's Included:New Quick Release wheel locks with a lighter, completely redesigned aerodynamic profile and matte finishUser manualFeatures:New wider rim profile that has been optimised for 25 and 28mm tyresUSB Ceramic bearingsMicro-adjust allows you to set preload on the bearingsOversized aerodynamic spokesDifferentiated rim heightG3 Spoke patternMoMag™ technologyOversized drive side flangeUse: Road, Touring, CommuterTyre Type: TubelessTyre Compatibility: Clincher/Two-way FitCassette Compatibility: Campagnolo FH Body 9/10/11/12, FH Body HG 9/10/11Spoke Material: AluminiumNipple Material: AluminiumWeight: 1505gBuy Campagnolo Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.
As with the mechanical parts, the rear derailleur represents the pride and joy of the EPS project and encompasses a series of technologies and innovations that allow shifting speed to be optimised and guarantee unprecedented precision, even in the case of multiple shifting with 11 sprockets at a timeThe EPS rear derailleur is comprised mainly of a mechanical structure, derived from the mechanical gear and composed of a derailleur rod/parallelogram/derailleur cage, of a worm screw enabled by an electronic actuator. As with the derailleur, the electronic rear derailleur actuator is composed of a gear motor and a sensor, the built-in resolver, that reads its movementsThe geometry of the parallelogram has been made more rigid and optimised to promote interaction with the electronic partsThe lower and upper bodies, the parallelogram and the carbon derailleur cage are moved by a screw system and lead worm screw (not a spring screw) which, in turn, is enabled by the electronic actuator that communicates with the DTI. The built-in resolver inside the actuator is capable of reading the movements of the rear derailleur at any time and optimising its position by communicating with the DTI (Digital Tech Intelligence)The rear derailleur is also equipped with a play recovery system using a helicoidal spring that optimises stability and precision and keeps operation and performance constant over time, even after many kms have been coveredAs with the mechanical rear derailleur, it is possible to optimise its position with respect to the frame and chain by acting on two adjusting screws: the screw that adjusts the mechanical end stop and the screw that adjusts the distance between the upper pulley and sprockets. By using these screws it is possible to optimise the installation of the rear derailleur and increase the precision of its operationDTI: Digital Tech Intelligence is housed inside the Power Unit and it continuously monitors the signals that arrive from all the EPS components, thus managing their operationMULTI-SHIFTING: There are no longer any limits to Multi-shifting and the choice is at the fingertips of the cyclistRIDE BACK HOME: The uncoupling mechanism of the rear derailleur is useful if the battery runs out on the road, allowing you to manually uncouple the rear derailleur to position it on which ever sprocket you requireWATER PROOF: In order to achieve the IP67 classification, all the electronic components of the EPS system underwent a series of tests, which proved their ability to function perfectly under one meter of water for at least 30 minutes

The Campagnolo Shamal Ultra C17 is the very first complete wheelset with each component in its build being specifically designed as a complete unit to ensure unparalleled efficiency and performance. This model has continued to introduce new technologies that would change the way aluminium performance wheels were produced. So advanced was the Shamal in its early stages, that it was found also in World Tour competition often and to this day is still perhaps the most race-ready aluminium wheelset available. The modern Campagnolo Shamal Ultra C17 Clincher includes all of the aforementioned technologies and represents years of solid research and development that culminates in the updated version of this prestigious line of wheels. This wider profile meets the C17 standard and is perfect for use with the increasingly popular tyre sizes. The updated Shamal was studied specifically to increase compatibility with 25 and 28mm road tyres. This rim/tyre interface proves to be more aerodynamic when compared to the same size tyres mated to a C15 rim. The C17 also allows for a more surefooted grip on the road in addition to increased comfort while increasing rigidity and thus reactivity at the same time thanks to its wider stance and optimised material usage. The advanced Shamal Ultra C17 represents the same fantastic performance that has made it THE go-to aluminium race wheel for the better part of two decades while adding more versatility and performance. Technologies: MoMag™ "Mounting Magnet" System: 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, reducing the overall weight. 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®. G3 Spoke System: When compared to a traditional wheel, Campagnolo’s G3 assembly architecture improves energy transfer, reduces the stress on the spokes, and increases lateral rigidity. G3 refers to groups of three parallel straight-pull spokes, which are arranged in a 2:1 ratio, so one side of the wheel has twice as many spokes as the other.
