Fulcrum SPEED 55C C17 Carbon Road WheelsetThe Fulcrum SPEED 55C features a 55mm deep profile, which not only provides exceptional aerodynamic performance but also offers optimized rolling efficiency and race ready stability. Although the deep section rim makes these wheels ideal for flatter terrain, the 1.47kg weight makes them extremely capable for courses that involve a lot of climbing, which benefit massively from lighter aerodynamic wheels.Optimal Tyre to Rim InterfaceThis wheelset features a 17mm internal rim width, making it perfectly suited to both 25 and 28c width tyres. It has been designed to create the optimal tyre to rim interface with these modern tyre sizes, placing it firmly in the modern competitive race wheel category. This wider rim/tyre setup grants additional rolling efficiency, traction, stability and comfort no matter what event or situation you end up being involved in.Unique Carbon Fibre ConstructionThese wheels feature the Longitudinal Twill carbon rim design, which is unique to Fulcrum. 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 with minimal flex.Optimised Braking PerformanceIn addition to the technology that give the SPEED 55C exceptional stability, aerodynamic finesse and high-end race performance, it also features the AC3 braking surface. This braking surface makes slowing down noticeably more responsive and powerful, which overall makes overall race times faster as you can brake later into corners with precise accuracy. This advanced coating on the braking surface provides optimised braking performance and as a bonus, it also reduces rim wear.Features: Material: Rim: Carbon; Front Hub: Carbon, Aluminium flanges; Rear Hub: Aluminium; Spokes: Stainless Steel; Nipples: Aluminium Discipline: Road, Triathlon Tyre Type: Clincher Rim Profile: 55mm Rim External Width: 24.2mm Rim Internal Width: 17mm Braking Surface: Twill, AC3 Treatment Axle Compatibility: Quick Release Spoke Type: Aero, double butted, straight pull Spoke Count: Front: 18; Rear: 21 Bearings: USB Ceramic, Cup and Cone Freewheel: Plasma Coated Weight: 1.47kgTechnologies: 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. Directionated 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. Unrilled 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.Buy Fulcrum Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.

Constructed from unidirectional carbon fibre and layered with a toughened ARC covering, each rim provides a rigid and protective performance on every outing. Finley balanced thanks to the 19mm internal width, these rims give as true and consistent a roll as possible as you tear across the tarmac. Fast-Paced, Carbon and Aluminium Road Wheels The front-wheel spins on a carbon hub on the front with an aluminium one on the rear, and both come with oversized aluminium flanges and USB (Ultra Smooth Bearing) ceramic bearings for a silky-smooth rotation. They also help the aluminium aero-shaped straightpull spokes to strengthen the build for the rigours and pressures of such pacy and lengthy riding. Ideal for gravel riding as well as intense road racing, this tubeless-ready duo is made to meet the demands of the modern rider.
Built for speed, this road bike wheelset features two high-quality full carbon rims with a "Twill" carbon fibre finish, which makes it more than ready for the demands of modern road cycling. Its carbon rim build also delivers increased strength, improved rolling resistance and an overall lower weight on your ride, so you can benefit from easier climbing and faster sprinting when on the flat. Road Bike Wheelset with CULT Bearings Fulcrum has kitted out this wheelset with its renowned CULT bearings, which allow for further weight savings and achieve unequalled levels of rolling resistance by up to nine times compared to traditional solutions, with a saving of up to 3.5 watts per pedal stroke. Along with the considerable improvement in terms of mechanical performance, this model is also equipped with an updated carbon front hub and an aluminium rear hub, both with an oversized aluminium flange. This means that riders will enjoy smoother, faster and more dependable rolling performance, wherever their ride takes them. 2-Way Fit Technology Featuring many of Fulcrum's finest technologies, this version is well-equipped for every mile of road thanks to 2-Way Fit technology. This technology allows riders to choose whether they run the wheelset as tubeless or as a standard clincher. By running tubeless, riders will enjoy performance advantages such as lower rolling resistance, greater stability and fewer chances of punctures or flats. This flexibility also means that you can personally test which of the solutions works best for you, as some riders prefer to use the clincher set-up for training and a tubeless setup for racing. One final highlight is the Fulcrum Speed 40 Comptz Disc Brake Carbon Wheelset has a 19mm internal rim width, which gives you additional freedom in terms of the tyres that can be fitted.

Reactivity and resistance are the key words of Fulcrum’s return to the MTB arena. These two concepts have guided the development of the new Red Zone Carbon, a wheel that can handle challenging off-road terrain for demanding riders. Carbon MTB Wheelset Red Zone Carbon is the result of a long research and development process that has involved all the elements of the wheel, both individually (rims, hubs and spokes) and, most importantly, as a whole, to create a wheel system that is able to meet the demands of high-level bikers. Lightness and reactivity on one hand, for maximum performance uphill, and a high level of vertical absorption and resistance on the other, for the peace of mind of riders who want to abandon themselves to the adrenaline of heading downhill with confidence. Direct Inmold Matt Finish (DIMF) A powerhouse of technology, Red Zone Carbon is Fulcrum’s new formula for modern MTB use, with all its experience distilled in each component. A functional and unique design is married with a new matt finish straight from the mould (DIMF), with all the specifications that a rider expects from an XC/Marathon or Down Country wheel: inner rim width of 28mm, light and extremely smooth rolling rim in a wheel that is fully-produced in Europe and most of it in Italy.

Tubeless technology was first used by the auto industry, then by motorcycles and now has reached the cycling industry. MoMag: What is MoMag? A magnet and lots of ingenuity. This was what led to the patent for the well-tested “Mounting Magnet” system, or MoMag. Wide Rim Tech: Fulcrum’s R&D department, following requests from the competition circuit, has worked to create rims that are wider than before, about 4 mm or more than previously. This technical choice provides an ideal basis for 25/28mm tyres, the sizes currently popular. This ensures stability, excellent handling and superior comfort. Undrilled Rim Bed: No holes on the bridge connector 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. Cup and Cone: The cup-and-cone bearing differs from the classic cartridge bearing because it works in perfect alignment with the forces involved, weight and thrust from the frame, as the bearings run in a race positioned directly opposing these forces.
