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.

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 all-new Rapide CL II wheelset brings the Rapide CLX II’s speed, efficiency, incredible handling, and stability in any conditions to more riders. Built on the exact same rims as the Rapide CLX II to elevate all this performance with tubeless-done-right technology, the Rapide CL II makes that performance easier to catch at check-out and you almost impossible to catch on the open road.Deep-section front rims are affected adversely by crosswinds. This negatively impacts handling, in turn causing a rider to slow down. By utilizing the first modeling algorithm designed around riders’ real-world reaction times and validated by on-road testing, we developed a front rim that both reduces drag AND increases stability by 25% in sudden wind gusts compared to our previous 50mm rims.The rear wheel is the last thing the wind sees, so we developed that rim shape to minimize drag at the trailing edge of the bike. At 60mm deep with a 30mm external width, the Rapide CL II rear rim reduces turbulence and yields the greatest aerodynamic benefit. Since the rear wheel doesn’t affect steering the way the front does, this deep section doesn’t adversely impact handling. Together, they represent the fastest package for real-world race conditions.The Rapide CL II is hand-built every step of the way, from the initial lay-up to the final tensioning on the nipples. Built on DT Swiss 350 hubs with 36t Star Ractch and Competition Race straight pull spokes, the result is a set of wheels designed as a complete system that weighs just 1590 grams a set, delivering incredible reliability, durability, and performance.The reduced rolling resistance of a tubeless setup is undeniable, as are the benefits of improved handling and incredible puncture protection. The development of the Rapide CL II involved the most rigorous and extensive engineering and testing program we’ve ever undertaken and resulted in a wheelset that almost doubles current industry impact standards while managing to achieve the lightest weight possible. The Rapide CL II utilizes a hooked rim (allowing for real-world riding pressures up to 110psi, if that’s your thing) for secure tire bead retention and an easier set up and mounting experience than ever before.Wheels sold individually (front or rear).Rim: Rapide CLX Carbon Clincher, 700c, Disc Brake, Tubeless.,Rim Details: Rear - 60mm Depth, 30mm External Width, 21mm Internal Width.,Hub: DT Swiss 350 Straighpull Center Lock, Star Ratchet 36t internals (10 degs) , 100x12mm & 142x12mm, Shim.

Zipp 858 NSW Carbon Tubeless Rear WheelZipp's ultimate aero weapon is now tubeless ready. That means you get the many aero advantages of the 858 NSW Tubeless rim-brake rear wheel with the added benefit of increased cornering grip and compliance with reduced rolling resistance. The rear wheels' 19mm internal width is optimised for running wider tyres at reduced air pressure. The 858 NSW's undulating 77/82mm-deep rim shape, the brand's proprietary Sawtooth profile, takes design cues from nature for Zipp's highest performing wheel when it comes to aero efficiency and crosswind stability. These structures inspired Zipp advanced development engineers to, for the first time, systematically apply biomimicry to solve the complex challenge of designing a wheel, with the undulating Hyperfoil nodes, that reduce both aerodynamic drag and side force. Simply put, the 858 NSW Tubeless is ideal for those focused on triathlon, time trials, or aggressive road riding.SawtoothSawTooth is the name given to Zipp NSW's patented variable depth 53/58mm rims. Developed utilising the principles of the emerging science of biomimicry, Zipp engineers began the rigorous aero development process of SawTooth utilising the wind tunnel, CFD, and real-world testing. The result is a rim shape that takes nature's most elegant design solutions and combines engineering precision to deliver a wheel that performs unlike any made before. This patented new rim shape achieves something conventional aero wheels cannot; it simultaneously reduces both aerodynamic drag and side force for the ultimate in AeroBalance. Sawtooth accomplishes this with a series of patented fin-shaped Hyperfoil nodes along the inner diameter of the rim that works together with Zipp's new HexFin ABLC dimples for improved airflow. The result is Zipp's highest performing rear wheel ever realized with both aero-drag reduction and reduced side force at all wind yaw angles. This is important because higher wind yaw angles are where bike handling is most affected by the wind.ShowstopperZipp's industry-leading Showstopper brake track continues to evolve and improve, providing unmatched stopping power and modulation regardless of weather conditions or the length of the descent. Showstopper is a complimenting pairing of a directional, moulded-in, texture with silicon carbide particles suspended in the surface resin. The current media blast process applied to all Zipp rims increases the surface roughness of the brake track providing the rider with consistent and responsive braking.Axial ClutchWith Cognition's Axial Clutch technology, Zipp has reduced drag by disengaging the ratchet mechanism when coasting. With less internal hub drag a rider can pedal less when drafting in a headwind, achieve higher speeds when coasting in an aero tuck, or opt to stop pedalling a moment sooner before entering a corner and bank that wattage for use exiting the corner. Axial Clutch technology also allows riders to maintain speed through corners that don't require braking input, thereby increasing corner exit speeds. Inside the Axial Clutch mechanism, Zipp uses magnets, rather than steel springs, to move and engage Zipp's lightweight Metal Injection Moulded (MIM) ratchet rings for unmatched reliability and consistent operation. With 36 points of engagement that all interlock simultaneously, there isn't a more secure freehub mechanism on the market.ImpressThis rear-wheel employs Zipp's ImPress graphics technology, which prints graphics directly on the wheel, to help allow the dimples to do what they were designed to do - help control vortex shedding, the rate at which air sheds off the wheel. Managing this is crucial to stability.Features: Rim Material: Carbon with UD Fibre finish with Impress technology Use: Road Axle Type: QR 135mm (quick release) Internal Rim Width: 18mm Rim Depth: 82mm Rim Profile: Symmetrical Brake Compatibility: Rim Brake Size: 700c Tyre Compatibility: Clincher, Tubeless Ready Surface Texture: ABLC HexFin Nipple Material: Aluminium Nipple Anti-rotation: Sapim Secure-loc Spoke Type: CX-Ray - Black Spoke Count: 24 Spoke Pattern: 2 Cross Hub: Cognition Axle Material: Aluminium Bearings: Cartridge - Stainless Steel Driver Mechanism: Axial Clutch Driver Body Material: Aluminium Max Tyre Pressure: 125psi Max Recommended Rider Weight: 250lbs Single or Pair: Single rear wheelTechnologies: New Zipp graphics and cosmetic identity that screams speed, applied using Zipp's ImPress direct-print technology. 19mm internal width and tubeless compatibility for optimisation of wider tyres with lower tyre pressure.

This scalloped design maintains the bearing bore diameter when high radial spoke tension is applied. That means you get bearings that quietly stay in place, roll faster, last longer, and provide a laterally stiffer hub. Impress: Zipp has employed ImPress graphics technology on this model, which prints graphics directly on the wheel, to help allow the dimples to do what they were design to do - help control vortex shedding, the rate at which air sheds off the wheel. Managing this is crucial to stability. Sawtooth: SawTooth is the name given to Zipp NSW's patented variable depth 53/58mm rims. Developed utilising the principles of the emerging science of biomimicry, Zipp engineers began the rigorous aero development process of SawTooth utilising the wind tunnel, CFD, and real-world testing. The result is a rim shape that takes nature's most elegant design solutions and combines engineering precision to deliver a wheel that performs unlike any made before. This patented rim shape achieves something conventional aero wheels cannot; it simultaneously reduces both aerodynamic drag and side force for the ultimate in AeroBalance. Sawtooth accomplishes this with a series of patented fin-shaped Hyperfoil nodes along the inner diameter of the rim that work together with HexFin ABLC dimples for improved airflow. The result is Zipp's highest performing wheel ever released with both aero-drag reduction and reduced side force at all wind yaw angles. This is important because higher wind yaw angles are where bike handling is most affected by the wind. Axial Clutch: With Cognition's Axial Clutch technology, Zipp reduced drag by disengaging the ratchet mechanism when coasting. With less internal hub drag a rider can pedal less when drafting in a headwind, achieve higher speeds when coasting in an aero tuck, or opt to stop pedalling a moment sooner before entering a corner and bank that wattage for use exiting the corner. Axial Clutch technology also allows riders to maintain speed through corners that don't require braking input, thereby increasing corner exit speeds. Inside the Axial Clutch mechanism Zipp use magnets, rather than steel springs, to move and engage the lightweight Metal Injection Molded (MIM) ratchet rings for unmatched reliability and consistent operation. With 36 points of engagement that all interlock simultaneously, there isn't a more secure freehub mechanism on the market. XDR Freehub Option: The XDR driver body option is available to select separately. It is a universal mounting system for cassettes that incorporate cogs with fewer than 11 teeth. It allows for lighter and more versatile drivetrains without requiring new rear axle standards, cassette tools or hub redesigns. The XDR interface is 1.85mm longer than XD and is designed for road hub applications. XDR driver bodies are compatible with all XD cassettes when the cassette is installed with a 1.85mm spacer.Manufacturer's Part Numbers: Shimano/SRAM 10/11 speed: ZPWH8617000 SRAM XD XDR 10/11/12 speed: ZPWH8617001Buy Zipp Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.
