Lightweight Rim Prime has experimented with numerous types of resin and tested countless new lay ups before it settled on its new and improved Primavera 38 rim. But, that’s not all, the brand has upgraded to a higher grade of carbon, saving 40g per rim, and improving on the impact strength/weight ratio making the new Primavera 38 their best rim yet. Wider = Improved Performance The Prime Primavera 38 Carbon Wheelset features a 38mm deep aero rim profile to deliver benefits across multiple yaw angles. A wider rim profile creates a more linear contour with the tyre to increase the Primavera 38's aerodynamic properties. Greater Strength To Weight Ratio Built up using the R010 CNC machined 7075 hubset and DT Swiss straight pull spokes the Prime Primavera 38 Carbon Wheelset creates a stiffer wheel with a greater strength to weight ratio and more reactivity. Shave The Seconds If you're looking for an upgrade to shave the seconds away, the Prime Primavera 38 Carbon Wheelset is the wheelset you need to tame any terrain.

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.
Mavic Deemax Pro Sam Hill Edition MTB WheelsetThis limited-edition wheelset features the specs that helped Sam Hill win two EWS World Championships, with added special graphics to really make you stand out on the trail.

Maxtal: Exclusive to Mavic, this specific aluminium alloy offers a higher strength to weight ratio than conventional 6106 alloy. Fore: Instead of being drilled, the lower rim bridge is pushed up on the inside, then threaded to enable the spoke nipples to be directly screwed in, leaving the upper rim bridge intact.
