Fulcrum Wind 75 Carbon Road Disc WheelsetThis race-ready wheelset features a high, ultra-aero profile that's ideal for time trials, triathlons and all situations where aerodynamics make the difference when pedalling at high speeds on your road bike. Fulcrum has equipped it with a high-quality full carbon rim construction with unidirectional carbon fibre finishing, so riders can enjoy the best balance of stiffness, strength and low weight performance on their ride. Aerodynamically researched and wind tunnel tested by the brand's engineers for maximum results, its rim width is 27mm and the channel width is 19mm which puts its internal and external dimension in line with modern racing trends.Full Carbon Wheelset with 2-Way Fit TechnologyFulcrum has kitted out this wheelset with a 2-Way Fit profile, which allows riders to fit both a tubeless tyre or a classic clincher. The advantages are indisputable, as the brand's tests have highlighted a unique increase in smoothness and it doesn't need any tape for sealing, simplifying and lightening the tyre-rim pairing. Because there is no tube, the friction caused by rubbing against the tyre is eliminated, while the perfect adherence of the tyre to the rim prevents the dispersion of energy. This also means that you'll have more flexibility to choose and test out which tyre works best for you. Tubeless advantages include the ability to run lower pressures for increased grip, comfort and fewer chances of flats or punctures.AFS Disc Brake Compatible and Aero Mo-Mag TechnologyReady for modern racing, this versatile wheelset is equipped with renowned Fulcrum technologies for getting the best performance out of every situation. Its AFS disc brake compatibility ensures that braking is powerful, precise and consistent, so you can tackle whatever the terrain or course conditions throw at you. Another highlight is its Mo-Mag technology that uses no holes on the rim to ensure 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, for greater weight reduction.Double-Butted Spokes with Sealed Cartridge BearingsThis model's spokes are double-butted, rounded and straight-pull for excellent aerodynamic performance and the nipples are aluminium. As far as the internals are concerned, Fulcrum chose sealed cartridge bearings housed in aluminium hubs, for both the front and rear wheel. Coming complete with sleek graphics that will complement any ride, the Fulcrum Wind 75 Disc Brake Carbon Wheelset the perfect choice upgrade for increased speed, comfort and handling on race day.Features: Rim Material: Full Carbon Finish: Unidirectional (UD) Carbon Fibre Use: Road, Triathlon and Time Trial Axle Compatibility: Front: 12x100mm; Rear: 12x142mm Rim Height: Front and Rear: 75mm Rim Width: 27mm Inner Rim Width (Channel): 19mm Braking System: Disc Brake Braking Surface: AFS Tyre Type: 2-Way fit (for Clincher and Tubeless) Tyre Width: From 23mm to 50mm Profile Height: High Spokes Material: Stainless Steel, double-butted Spokes Profile: Rounded, straight-pull Front Wheel Spokes: 24 (Left: 16 left; Right: 8) Rear Wheel Spokes: 24 (Left: 8; Right: 16) Nipples: Aluminium Front Hub: Aluminium, Aluminium flanges Rear Hub: Aluminium, Aluminium flanges Bearings: Sealed cartridge bearings Axle Material: Aluminium Axle ASTM Category: 1 Weight Limit: 120kg (bike, rider, equipment and luggage) Freehub Type: Multiple options available to select separately Single or Pair: Pair Weight: 1820gTechnologies: 2-Way Fit: 2-Way Fit profile for tubeless and clincher. Fulcrum has developed 2-Way Fit technology to ensure perfect compatibility of its tubeless rims with normal clincher types and tubes. 2-Way Fit road bike wheels are perfectly multipurpose for tackling every situation. Thanks to a special impression in the valve area, the tubes are fitted with maximum precision, while keeping the tube perfectly stable inside the tyre. Housing the valve for tubeless tyres is also risk-free, with the unquestionable advantage that there are never any air infiltrations caused by non-ideal positioning when fitting. AFS Axle System: The Axial Fixing System is the solution developed by Fulcrum to fix the disc brake to the hub. The constraint granted by the butt area of the release mechanism, greater than in familiar standard ones, makes it possible to obtain greater structural rigidity and therefore more precise and powerful braking. Full Carbon Rim: Full carbon Fulcrum rims are built using combinations, developed in the laboratory, of different types of fibre, including unidirectional (UD). To build them Fulcrum developed a special HTG (high transition grade) resin, whose glass transition point is at a higher temperature than any other fibre used in the bicycle industry. This gives incomparable performance when braking. Fulcrum carbon products are also recognisable for their sophisticated workmanship: The rims are moulded with ready-made nipple holes, so no further hole-making is needed. Nor is polishing necessary to give them an impeccable appearance or make them technically ready for mounting. MoMag: A magnet and lots of ingenuity. This was what led to the patent for the well-tested “Mounting Magnet” system, or MoMag. No holes on the rim mean 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, to the benefit of weight reduction. 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.Manufacturer's Part Numbers: FULC0146827 Black 700c Shimano FULC0146829 Black 700c SRAM XDBuy Fulcrum Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.

Taking the notion of combining flagship performance with workhorse dependability one step further we’re introducing the Terra C. This shares the same hub and spoke architecture as the Terra CL ensuring ease of service and spoke replacement should the need arise and is paired with an entirely new rim layup. The rims on the Terra C share the same dimensions and broad range of tire mounting possibilities as the Terra CLX and CL – 33mm deep with a 25mm internal width – but are crafted using a new-to-us process known as Resin Transfer Molding. This is an automated process that allows us to very precisely control how resin is introduced to the layup which in turn ensures maximum strength and material performance. The end result is an incredibly tough set of wheels that you can beat on to hell and back.

Mavic Cosmic SL 65 Road Disc WheelsetPerfect for flat road races or windy triathlon events, this wheelset is kitted out with an updated Mavic rim shape that boasts a lighter overall weight as well as easier to use Road Tubeless technology. Its 100% carbon fibre rim construction means that it's strong and stiff when climbing, without any unnecessary grams holding you back as you descend. The reduced inertia of the lightweight rim delivers instant acceleration, while its lighter spokes make the wheelset feel snappier. Its 65mm deep and 26mm wide NACA rim profile also delivers low drag and stability in crosswinds, so you can get the best out of every ride.Wind-Tunnel Tested Carbon WheelsetThe wide, rounded shape of the Cosmic SL 65 rim was developed through countless hours in the wind-tunnel to produce the lowest possible drag without sacrificing stability in crosswinds. Updated and refined spokes make it 80g lighter than its predecessor, the Comete Pro Carbon UST Disc. With a revised rim bed shape, this model is easier than ever to fit tubeless or tube-type tyres. Mavic's new Infinity hub platform optimises the spoke lacing for efficient power transfer through highly controlled spoke tension. And the Instant Drive 360 freewheel coupled with automatic bearing preload (QRM Auto) provides fast engagement, high stiffness and extra durability.Centre-Lock Disc-Brake ReadyThese wheels are engineered specifically for disc brakes, with an optimised spoke count and lacing.
