Fox Suspension 36 Float Performance Elite Grip 2 ForkPart of the prestigious Factory Series, this high-quality mountain bike (MTB) suspension fork comes trail-ready with anodised upper tubes for hard-wearing performance and durability wherever your next ride takes you. Engineered for everything from day long epics on your favourite trails to modern enduro racing, it's kitted out with Boost axle spacing for extra stiffness as you dominate your way around the mountain. Another highlight is its lightweight Float EVOL air spring and GRIP2 damper with Variable Valve Control (VVC) for undisputed tuneability and control. As a result, it's easy to dial in your settings to match your riding style as well as the terrain. Coming complete with 160mm travel as well as many of the brand's finest technologies, this is a great choice of upgrade for conquering everywhere from big backcountry routes to the EWS circuit.MTB Fork with GRIP2 DamperFox Suspension's GRIP2 damper is the benchmark for unparalleled ride quality and ultra-precise adjustability. GRIP2 includes the brand's patented Variable Valve Control (VVC) technology which allows for external fine-tuning of suspension performance. GRIP2 achieves with the twist of a knob what typically requires the time-consuming and complicated task of completely disassembling and reassembling the fork.Float EVOL Air SpringEVOL technology increases negative air spring volume, optimising small bump sensitivity. EVOL's linear spring curve delivers plushness off the top, extra mid-stroke support, and more tuneable bottom-out progression. The benefits of EVOL are further enhanced by Fox Suspension's updated Lower Leg channels and Bleeders, which both function to reduce air pressure captured in the lower legs, allowing the EVOL air spring to operate freely without unintended interference.Features: Upper Tubes Finish: Anodised Use: Mountain Bike (MTB), Enduro Axle: 15QRx110mm Boost Steerer Diameter: 1.5" tapered Air Spring: Float EVOL Damper: GRIP2 Variable Valve Control (VVC) Travel: 160mm Rake: 44mm Brake Rotor Compatibility: 180mm direct Post Mount, Up to 230mm compatible Starting Weight: 1965gTechnologies: Performance Elite: Performance Elite forks retain the same adjustments, features, dampers, weight, and 7000 series aluminum upper tubes as Factory Series, but have black anodised stanchions instead of Genuine Kashima Coat. Adjustments: High-speed compression (with VVC) 8 clicks. Low-speed compression 16 clicks. High-speed rebound (with VVC) 8 clicks. Low-speed rebound 16 clicks. Floating Axle: Floating axles might look similar to other axles, but in fact they offer a distinct performance advantage due to their unique ability to match the exact width of the fork's wheel mounting surface precisely to the front hub flange spacing, thus creating perfect chassis alignment and eliminating unwanted friction between the upper and lower fork legs. Floating axles provide much smoother suspension movement throughout the entire range of the fork's travel, notably improving sensitivity and overall ride quality. The all-new 36 and 38 come equipped with a new quick-release lever operated patent-pending floating axle system, combining the benefit of a floating axle with the ease of a tool-free quick-release. With this system, spacing is locked in via a floating sleeve, allowing repeated front wheel removal and reinstallation while maintaining perfect fork alignment. Floating sleeve positioning comes preset from the factory so if you are unsure of how to operate the floating axle system or simply don't want to bother with it, you can just install the front wheel and get on with your ride. Lower Leg Bypass Channels: As a fork compresses, the air volume within the lower legs decreases, increasing air pressure. The more the fork compresses, the more pressure increases. This effect can have the unintended consequence of preventing full travel from being achieved. Fox Suspension's lower leg channels help alleviate this issue by dramatically increasing air volume within the lower legs and thereby reducing the amount of additional unintended pressure ramping. Another benefit of these channels is that lower leg bath oil is circulated to the upper reaches of the lower legs, continuously lubricating the foam rings and bushings as the fork compresses and extends through its travel. Bleeders: Fox Suspension's lower leg bleeders allow for atmospheric pressure equalization at the simple press of a button. Pressure build-up in the lower legs dramatically decreases fork performance, preventing full travel from being achieved, and diminishing small bump sensitivity and responsiveness. Lower Leg Arch: Stiffness-to-weight is the ultimate metric for bicycle design. Engineers invest countless hours poring over every ounce of material in an effort to optimize this critical ratio. Fox Suspension's all-new lower leg design pulls out all the stops, shaving every possible gram while making sure not to compromise stiffness or strength requirements of modern enduro and gravity style riding. Modern frame designs and geometry trends require modern suspension design solutions. The arch design of the all-new 36, 38, and 40 is designed to pair perfectly with modern Enduro and Downhill bikes. Head tube profiles have grown larger and larger, and fork offsets shorter and shorter. Fox Suspension's new arch shape takes this need into account by jutting forward to provide ample headtube clearance at full compression. State-of-the-art computer modeling techniques helped us to create an organic lower leg shape that optimizes stiffness with the absolute minimal amount of material. GRIP2: High-speed compression now with patented VVC (Variable Valve Control). GRIP2 is Fox Suspension's next-evolution sealed cartridge FIT system, the brand's highest-performing gravity-focused damper.Manufacturer's Part Numbers: 910-20-239 Black 27.5" QR110 160mm 44mm 910-20-232 Black 29" QR110 160mm 44mmBuy Fox Suspension Components from Chain Reaction Cycles, the World's Largest Online Bike Store.

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.

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.
