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.

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.

Strong and Stable, Carbon-Rimmed Road Wheels Built with a 55mm depth, the unidirectional carbon rims stay rigid and responsive with each roll and cope admirably with the harshest crosswinds to keep you perfectly balanced at high speeds. Supported by durably-made alumnium hubs and strengthened with stainless-steel spokes, both wheels provide a buttery-smooth rotation and slice through the air with aerodynamic excellence. Disc brake-compatibility enhances the stopping abilities of this rampant wheelset, while the Two-Way-Fit tubeless-ready design improves cornering grip and puncture protection when using lower inflation tyres. With such high-end qualities throughout each wheel, the Wind 55 DB wheelset is an essential choice for the focused road rider.
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.

Whether you're enjoying a day-long epic ride on your favourite MTB trails with your riding buddies or exploring new mountain routes on your own solo adventure, this versatile wheelset is engineered for reliable performance wherever your ride takes you. Fulcrum has kitted out this model with durable aluminium rims that have been put through the brand's square milling and CNC-machining process to deliver maximum strength without adding any unnecessary weight. This results in a more capable wheelset that can handle the intensity that's associated with charging across demanding terrain conditions at speed, across rock gardens, tree roots and debris. Aluminium MTB Wheelset Fulcrum’s second MTB wheel is the result of the experience matured in the development of the Red Zone Carbon. It’s designed for a wider range of riders looking for a reliable and resistant product for off-road fun and performance. Amongst the technical specifications derived directly from its older sibling we find the hubs and the spoke count of 24 on the front and 28 on the rear. The CNC machined aluminium rim has a profile of 19mm and an inner rim width of 25mm. Aesthetically the wheel is completed with an advanced finish that marries a double polished-matt surface with laser-etched graphics. The Fulcrum logo can be found inside a red box, which can also be replaced with a reflective adhesive, black on black, included with the wheels. The Red Zone 3 is an all-purpose wheel, which is extremely versatile and suited to multiple uses: training wheels, sturdy race wheels or the perfect base for adventure bikes (boost gravel). Boost Axle Spacing Built for modern MTB trail riding, the Fulcrum Red Zone 3 Wheelset is equipped with Boost axle spacing for stiffer and stronger rolling performance across harsh and unpredictable terrain conditions. Its 15x110mm front spacing and 12x148mm rear spacing gives it extra stability as you carve your way from trail to trail.

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. Square Milling: For the new Racing Zero’s aluminium rim, Fulcrum decided to keep the triple-milled structure throughout the profile to minimise aluminium thicknesses. Next, Fulcrum's technicians added 3D milling at the base of the spokes. This means less material but the same reliability since, in this particular design, the forces are well distributed over the rim. Triple and “Square” milling enable maximum weight reduction on the rim periphery, producing an extremely responsive wheel. Asymmetric Rim: The asymmetry is designed to improve rim tension, balancing the forces from brakes and sprocket cassette.

Specifically designed for gravel riding, this versatile wheelset is perfect for spending the weekend exploring backroads and countryside adventures. It features a high-quality full-carbon rim construction, which makes each wheel durable and stiff, while also keeping the weight impressively low. Fulcrum has also given each wheel a unidirectional (UD) carbon fibre finish, making it look as awesome as it performs. Coming complete with an aerodynamic profile and a range of technologies including Tubeless Ready and 2-Way Fit, this model is a great choice of upgrade for conquering every mile on your gravel bike. Carbon Fibre Gravel Bike Wheelset Fulcrum Rapid Red Carbon: discover new horizons fast. The Rapid Red family of wheels now boasts a set of wheels dedicated to those who want to discover new terrains and new trails, with a touch of extra speed. Fulcrum has applied the technological know-how from their top-of-the-range wheels to develop the reactive, light, and reliable Fulcrum Rapid Red Carbon, for gravel (and for whatever gravel means to you). Lightness and reactivity are guaranteed by the S-Shape asymmetrical profile carbon rim. This technology improves the balance between the tension of the spokes. The optimised balance ensures long-term performance levels. Moreover, the unique shape of the rim profile increases stiffness by 2.5% compared to a traditional U-shaped profile. 2-Way Fit Ready To achieve maximum performance with tubeless tyres, the Rapid Red Carbon features a tubeless-specific non-drilled bridge: 2-Way Fit. The non-drilled bridge has a C-Lux Finish, a mirror-like finish that makes it easier to install the tyre. The wheel assembly is completed with Fulcrum's patented Mo-Mag technology, which uses a simple and ingenious solution to seat the nipple on the rim hole with a magnet. The rim has a 30mm high profile with a mini-hook system that extends its compatibility with a wider range of pressures (the only limit is the one given by the tyre). Moreover, Fulcrum’s dimensional precision guarantees greater safety against the tyre rolling off the rim at low pressures, thanks to the larger support surface available with the wider inner rim width of 25mm. And as you’ve come to expect from #fulcrumfast, Fulcrum has also employed functional solutions that marry aesthetics and performance. At a glance, you will immediately notice the new Direct Inmold Matt Finish (DIMF). The Fulcrum Rapid Red Carbon is the perfect solution for demanding riders looking for a top-of-range product with “made in Europe” technology. Technologies: 2-Way Fit Profile for Tubeless and Clincher: Tubeless technology was first used by the auto industry, then by motorcycles and now has reached the cycling industry. After its debut with mountain bikes the moment has come to “put it on the road”, and that’s what Fulcrum propose to do. The brand has developed its 2-Way Fit technology to ensure the 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. Rim Dynamic Balance (RDM): The concept is simple and elegant: balance the weight of the gasket, with an item of similar weight placed on the exact opposite side. Momag: A magnet and lots of ingenuity. This was what led to the patent for the well-tested “Mounting Magnet” system, or MoMag. Fulcrum Identification Card (FIC) - 100% Handmade Quality: Right from its inception Fulcrum has been marked by the feature that continues to this day: that to design, prototype and industrialise all the wheels characterised by the red “F”. Indeed these take shape inside of the R&D, the leading-edge department that represents the beating heart of the Italian company. Every single component of the wheel, the materials chosen and the technologies applied are the tangible result of the effort that Fulcrum makes every day to give you maximum performance and reliability. 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 Technology: Full carbon Fulcrum rims are built using combinations, developed in the laboratory, of different types of fibre, including UD and the famous 90-degree 3K of models at the top of its range. 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. 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, and 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.
