With stunning acceleration, the new Dura-Ace R9270 C36 wheelset will change the way you experience climbs, corners, even stoplights. This is because it isn't just how much a wheel weighs but where the weight is on the wheel that matters. The all-new C36 design shaves mass at every opportunity but especially at the rim. The result is a lively wheelset that can transform your ride. Lighter, Wider and Faster Carbon Road Race Wheel With both a lighter, wider all-carbon rim and a lighter hub, the new Dura-Ace C36 won't shy away from a day of climbing. The new rim is 36 mm deep and still delivers good aerodynamic efficiency despite its gossamer weight. Meanwhile, the hub features an alloy freehub body and a new engagement mechanism for increased rigidity. Centre-Lock Disc Rotor Mount The Centre Lock system makes an easy rotor installation possible with a spline mount and a lock ring. The lock ring mounting system reduces the total working hours by shortening the amount of time of both installation and de-installation. In addition, the secure fixing by the spline mount enhances precision and rigidity while improving braking efficiency. D2 Aerodynamic Rim Profile Aerodynamic performance is affected by wind direction. To create the D2 rim, Shimano engineers considered both frontal and crosswinds, aiming to achieve optimal performance in real-world riding conditions. Extensive prototype testing, in the wind tunnel and on the road, proved that a wide rim shape with a deep tire bed performs best across a wide range of conditions. At yaw angles ranging from 0 to 15 degrees, the Shimano D2 rim profile reduces air drag better than others aero shape rims. This rim design also boosts lateral wheel stiffness and offers improved vertical compliance for increased control, comfort and durability on the road. Rear Wheel OPTBAL Spoke System The OPTBAL rear wheel spoke system features 21 spokes—14 on the drive side and 7 on the non-drive side. Cassette spacing in today’s wheels produces unbalanced tension in traditional 1:1 spoke systems. This unbalance is intensified with the 11-speed cassette, producing nearly double the tension on the drive side spokes. Generally, high and low tension spokes have respectively tendency toward breaking down and coming loose spoke nipples. Unbalanced tension affects durability and strength. The OPTBAL design rebalances spoke tension, enhancing wheel rigidity and strength for a more durable wheel. Shimano E-Thru Axle System The tool-less type thru-axle skewer system optimizes rigidity and weight balance and enables easy operation with a reliable internal cam mechanism. The 15 mm thru-axle system is 15% stiffer torsionally and 25% stiffer in transverse shear than a traditional 9 mm quick release front axle system. High rigidity is secured while keeping the optimum weight balance. The E-Thru axle hub system minimizes the distortion of suspension while maintaining lightweight for riding around sharp corners at high speed.

Fulcrum Red Zone 3 WheelsetEngineered for dependable performance wherever your mountain bike (MTB) takes you, this versatile wheelset is perfect for all-day epics on the trails and exploring new mountain routes. 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 WheelsetFulcrum'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 SpacingBuilt 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.Features: Rim Material: Aluminium with Square Milling, CNC-machined Use: Mountain Bike (MTB) Rim Width: Inner: 25mm; Outer: 29mm Rim Height: 19mm Asymmetric Profile Height: Low Axle Size: Front: 15x110mm (Boost); Rear: 12x148mm (Boost) Brake Type: Disc Brake Tubeless Ready: Yes 2-Way Fit Ready: Yes ASTM Category: 3 Braking Surface: AFS Front Wheel Spokes: 24 Rear Wheel Spokes: 28 Spokes Material: Stainless Steel - Double Butted Spokes Profile: Rounded, straight pull Nipples: Aluminium Front Hub: Aluminium Flanges Rear Hub: Aluminium Flanges Freehub: Multiple options available to select Bearings: Adjustable Cup and Cones bearing Others: Optional Reflective "F" sticker Weight Limit (System): 125kg ASTM Category: 3 Single or Pair: Pair Weight: 1610g Technologies: Wide Rim Tech: Fulcrum's Research and Development 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. 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.

Zipp’s 303 S Tubeless Disc Brake wheelset provides today’s cyclists the versatility they demand with the speed they crave. Expanding greatly on its heritage of conquering the Spring Classics this 303 wheelset maintains its ideal-for-every-terrain 45mm rim depth but adds a significantly wider internal width to provide greater performance and ride quality in almost every measurable way. Road bikes are more versatile than ever no matter the road surface but just as fast as before. The 303 S offers an entirely new rim profile and design to optimize rider performance on this new breed of bike. This wheelset is tubeless for disc-brake bikes allowing the ability to run wide tires at lower pressures for race-ready speed on or off the pavement. The 303 S is among our lightest wheelsets optimized for top aero performance with a 28mm tire but capable of handling gravel tires up to 50mm wide. The 303 S borrows design concepts from the higher-level 303 Firecrest Tubeless Disc-brake wheelset to gain speed through increased efficiency. That is achieved by creating a wheel with reduced: Wind resistance rolling resistance rider fatigue and weight. The key innovation is in the 303 S Series’ rim design. Its 45mm rim depth is the same as its predecessor the 302 Disc brake. But its rim width is 2mm wider at 27mm and its tire bed is a full 7mm wider at 23mm. That rim platform is designed to be the fastest with a 28mm tire. The wide rim optimizes tire profile to allow lower tire pressure. That helps to reduce rolling resistance and provides a more compliant ride. The result of all this is a 10 percent watt savings vs. a top peer wheel in total power required to ride 40kph on a smooth flat road with a 28mm tire according to internal Zipp testing. This groundbreaking wheelset also features all-new cosmetics setting the rider apart from the pack and comes at an attractive price. FEATURES Zipp graphics and cosmetic identity that scream speed Fastest with 28mm fits wide gravel tires as well 76 / 176 DB hubs with Center locking interface XDR driver body option Wide rims optimize tire profile to allow lower tire pressure especially with tubeless. The result is a larger contact patch for increase grip for confident cornering descending and handling in wet conditions.
