Feel your bike come alive on the open road with the new Alpinist CLX II—the lightest best-handling clincher wheels we have ever made. Hyper-responsive acceleration magic in the corners sublime over rough roads all elevated with the performance of a tubeless system. There’s no room for a single excess gram whether you’re chasing summits or ride quality because perfection is only achieved when there is nothing left to take away. It takes more than a lightweight rim to deliver the incredible reactivity and handling of the tubeless Alpinist CLX II. The wheelset is designed as a system with our engineers controlling and testing every part of that system—hubs rims spokes lacing—and developing it hand-in-hand with Specialized Tubeless tires. The result is a 1250-gram tubeless wheelset with otherworldly ride quality. The Alpinist CLX II utilizes a hooked rim (allowing for real-world riding pressures up to 110psi if that’s your thing) for secure tire bead retention and an easier set up and mounting experience than ever before. All in a wheel that almost doubles current industry impact standards while managing to achieve the lightest weight possible. Our all-new LFD hubs are the spinning heart of the Alpinist CLX II. We carved 50 grams out of the previous Alpinist CLX hub with new low-profile hub bodies and machined rotor mounts.

Ultimate is not just a name it’s the word we reserve for pinnacle performance. And it’s how we define this wheelset. Cosmic Ultimate is the wheel choice for pro racers seeking a competitive advantage. This tubular tire version sees a major redesign for disc brakes with a new full carbon rear hub full carbon lacing ID360 freewheel technology and thru-axle compatibility.The rim is engineered with a NACA-inspired full-carbon profile that’s 40mm deep and 25mm wide. It’s made from 12k carbon fibers wrapped over a super rigid foam core. Full-carbon construction means the whole wheel is incredibly light at just 1235g. The 20 super-bladed carbon fiber spokes and high thin carbon hub flanges offer a proven aero advantage. The spokes are made with unidirectional carbon fibers so they don’t stretch. The spokes run continuously from one edge of the rim to the other through the hubs (R2R technology) creating one single spoke instead of two. This adds wheel stiffness and eliminates the need to mechanically attach the spokes to the hub.The rear rim is asymmetrical to improve its drive-side bracing angle so spoke tension is balanced and the wheel remains stiff under the heaviest lateral loads such as sprints or attacks. The axles are paired with automatically adjusted sealed cartridge bearings for perfect preload. At the back the ID360 freewheel system provides instant engagement and low friction. The hubs are thru-axle compatible (12x100 up front and 12x142 at the back) and made for Center Lock brake rotors. These wheels are designed engineered and patented by Mavic and are 100% handmade in our French carbon factory in Annecy.

The Campagnolo Bora WTO 45's are a carbon wheelset, designed and optimised for road racing over undulating terrain. While the 45mm deep rim helps these wheels slice through the air with speed, the structure of the rim itself enhances wind power at certain yaw angles, driving the athlete both further and faster for minimal effort. Despite these aerodynamic gains, the Campagnolo Bora WTO 45's weigh less than 1500 grams per pair - so you don't have to worry about your new wheelset holding you back when riding uphill. Campagnolo has designed this rim to accept larger tyres, to minimise rolling resistance, as well as maximising grip and rider comfort out on the road. However, thanks to the two-way-fit profile, if further grip, comfort and puncture protection is needed, riders can also run the Campagnolo Bora WTO 45's tubeless too. Although carbon wheels typically don't have the best reputation for wet weather braking, by applying the AC3 (All Conditions Carbon Control) technology to the braking track of this wheelset, Campagnolo has improved dry weather braking by 20% and wet weather braking by 40%. These advanced carbon rims are paired with a set of equally advanced hubs. While the alloy hub shell is designed for minimal drag, the ceramic USB cup-and-cone bearing system ensures a lasting smooth spin and maximised rider efficiency. These hubs are laced to the rims via 18 steel spokes on the front, and 21 on the rear. Using a cross-sectional spoke pattern allows for a considerable increase in wheel strength and durability, as well as a noticeable reduction in rolling resistance.

Representing the best in the business, the SPEED 40C C17 Carbon Road Wheelset delivers high-end performance and incredible versatility. Describing their creation as the pinnacle of wheel design, Fulcrum have used a solid and incredibly responsive structure with rear oversized flanges and a two-to-one spoke pattern. Capable of tackling any conditions, acceleration and braking are consistently at the top of their game come rain or shine. Perfect Tyre to Rim Interface This wheelset is capable on any terrain you come across. Featuring a 17mm internal rim width, it is perfectly suited to both 25 and 28c tyres. It has been designed to create the perfect tyre to rim interface with these modern tyre sizes, placing it firmly in the modern competitive race wheel category. Stiff and Reactive The Longitudinal Twill carbon rim design has been implemented into the creation of these wheels. The fibres and the orientation in which they are structured pushes the boundaries of carbon fibre construction, resulting in a stiffer, more reactive rim that can also absorb higher levels of road vibration. Exceptional Braking Performance In addition to the technology that Fulcrum has developed to make their wheel go amazingly fast. They have also applied the AC3 braking surface to this model, which makes slowing down noticeably more responsive and powerful. This advanced coating on the braking surface provides exceptional braking performance and as a bonus, it also reduces rim wear. Added features: Axle - Front Axle Compatibility: QR Rear Axle Compatibility: QR Aluminium Bearings - USB ceramic bearings. Adjustable Cup & Cones bearing system Rim Material - Full carbon, "Twill" -carbon fibre finishing Tyres - Clincher Width: From 25mm to 50mm Size: 28" Weight - 1420g Technologies: AC3 - All Conditions Carbon Control: AC3 enables surprising braking performance, which is very noticeable in difficult weather conditions. Rather than using the traditional machined brake track approach, Fulcrum uses micro laser incisions on the brake track surface to remove resins and create a smooth surface. Lab tests have shown that this process improves braking power by an improvement of 6%. However, in the wet this performance increase jumps to 43%. Bringing braking in the wet closer to the performance experienced when riding in dry conditions. USB (Ceramic Ultra Smooth Bearings): Using high-end ceramic balls, which perform continually thanks to the absence of lubricating grease and the precise machining of the cup and cone technology, the friction is reduced drastically and in turn increases the smoothness of triathlon and road bike wheels by as much as 9 times compared to standard bearings. Rim Dynamic Balance: Simple and Elegant, the weight of the rim gasket is balanced on the opposite side with an item of similar weight. 2:1 Two-To-One: Every push on the pedals from the rider will force most of that energy on the drive side of the rear wheel. To combat this loss of rim tension and power transfer, Fulcrum has solved this cycling problem with their 2:1 spoke ratio pattern by doubling the spoke count in crucial zones on the wheel. Direction Rim-Spoke Coupling: An exclusive rim/spoke mounting system. It allows the rim, spokes, hub and nipples to align perfectly, guaranteeing the precise spoke tension in all areas around the wheel. Anti-Rotation System: This system locks the spoke in place once the correct tension is achieved. Engineers at Fulcrum have designed this system to ensure the spokes never lose their initial tension and to remain in the position that has been proven to provide the perfect aerodynamic properties. Unrolled Rim Bed: Featuring no holes on the central section of the rim means that the rim is uniform at every point, free from critical areas subject to stress. The advantages are immediately clear: less weight, longer lasting rims, greater resistance to fatigue, the possibility of giving the spokes more tension and more stiffness which, in terms of performance, means improved responsiveness and acceleration. Plasma Freehub: The freehub body has been Plasma treated, which makes the aluminium especially hard and resistant to surface abrasion and wear. This means the thickness of materials used can be to be reduced to a minimum, achieving a lighter weight, while maintaining lifespan and reliability.
