Shimano Dura-Ace R9270 C36 Carbon CL Disc WheelThe Dura-Ace R9270 C36 Carbon CL Disc Wheel from Shimano is a Tubeless Ready mid-depth-profile wheel that's versatile for steep climbs, fast sprints and long days in the saddle. It features a 36mm-profile full-carbon rim and a Centre Lock disc rotor mount while being compatible with 12mm E-Thru axles, this race-ready wheel is fast, aerodynamic and stable for road racing anywhere.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 WheelWith 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 MountThe 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 ProfileAerodynamic 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 SystemThe 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 SystemThe 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.

Shimano Dura-Ace R9270 C50 Carbon CL Disc WheelThe Dura-Ace R9270 C50 Carbon CL Disc Wheel is Tubeless Ready and features an aerodynamic 50mm-deep-section full carbon rim. Designed and engineered to provide exceptional speed, agility and style, this quality carbon race wheel offers the perfect balance of aerodynamics and crosswind stability at a low weight. And it has a Centre Lock rotor mount for use with disc brakes and the rear wheel is compatible with Shimano HG 11 and 12-Speed cassettes.The all-rounder of the new Dura-Ace wheel line-up, the C50 is both lighter than the previous C40 model and nearly as aerodynamic as the previous C60. It's a wheelset at home in a wide range of conditions. From time trials to criteriums, on rolling terrain or attempting a personal best, the new C50 is the ideal wheel for spirited road riding.The perfect blend of low weight and aerodynamic performance, the all-new Dura-Ace C50 features an updated all-carbon tubeless rim and new hub design that drops weight while enhancing rigidity. Centre-Lock Disc Rotor MountThe 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 ProfileAerodynamic 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 SystemThe 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 SystemThe 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. Features: Series: Dura-Ace R9200 Series All-round tubeless wheels with balanced aerodynamics and lightweight materials 50mm height Full Carbon Rim Internal Rim Width: 21mm Disc Brake Mount: Centre Lock Disc D2 Aerodynamic rim profile Axle System: 12mm E-Thru / Hub Spacing (O.L.D.): Front: 100mm; Rear: 142mm Freehub: Shimano 12-Speed (Compatible only with Shimano road 12-Speed cassette sprockets) Tyre Type: Clincher Tubeless; Recommended Tyre Size: 25-622 - 32-622 Weight: 787g (rear); 674g (front)A 2-year warranty is offered with all Shimano products from Chain Reaction Cycles (3 years on Dura-Ace and XTR products).Buy Shimano Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
Shimano Dura-Ace R9270 C60 Carbon CL Disc WheelThe Dura-Ace R9270 C60 from Shimano features a quality full-carbon 60mm-deep Tubeless Ready rim and a Centre Lock disc rotor mount. This wheel is fast, agile and stable, and it's optimised with Shimano D2 Aerodynamic Rim Profiling - it's the ideal wheel design for time trial, triathlon and criterium events. And the rear wheel is compatible with Shimano HG 11 and 12-Speed cassettes.Perfect for flatter courses and time trials, the Dura-Ace C60 prioritizes aerodynamic efficiency and lateral rigidity. The new hub design, stiffer spokes, and deep-section rim are designed specifically to allow you to push harder in corners and ensure that every bit of your effort is translated into forward motion. Like the entire Dura-Ace wheel family, the new C60 started with a blank slate. Different from the C36 and C50, the C60 has a specific front hub design using Shimano's OPTBAL 2:1 spoke pattern to enhance lateral rigidity. The C60 also receives stiffer spokes, 1.8 mm instead of 1.5 mm. Tested by our professional athletes, this focus on the lateral rigidity of C60 allows you to push harder in corners and when manoeuvring at higher speeds. Lastly, the new wind-tunnel tested, deep-section rims feature a faster, more stable cross-section that time trialists, triathletes, and sprinters alike will enjoy. Centre-Lock Disc Rotor MountThe 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.
