Fox Suspension 32 Float SC Factory Fit4 Remote ForkThis mountain bike (MTB) suspension fork is specifically tailored for the rigours of cross country racing and features Fox Suspension's prestigious Step Cast chassis. Its Step Cast design offers a pioneering lower leg shape that isn't just for looks, its narrow stance and stepped design saves weight, decreases frontal area, and provides clearance for the spokes and brake rotor. Ready for the most demanding of cross country (XC) racing situations, this version is also kitted out with a lightweight Float EVOL air spring and a FIT4 2-position remote actuated damper (remote sold separately) for easy adjustment and fine-tuning to match your riding style. Part of the brand's renowned Factory Series, this model comes complete with a genuine Kashima finish on its upper tubes for slippery smooth, ultra-durable performance as you race for the podium.FIT4 2-Position RemoteIn its fourth generation, Fox Suspension's patented FIT4 closed cartridge system provides two on-the-fly compression damping positions (Open and Firm) to adapt to varying trail conditions. Factory Series forks feature an additional 22 clicks of low-speed compression adjust in the Open mode, allowing riders to fine-tune their exact damping preferences.Lightweight Float Air Spring SystemThis model's Float EVOL air spring automatically equalises the positive and negative air chambers for increased sensitivity and traction, regardless of the air pressure setting. Riders can fine-tune the characteristics of the positive air spring by using volume spacers.Please note: A remote is sold separately for this product.Features: Upper Tubes Finish: Genuine Kashima Coat Use: Cross Country (XC) Axle: Kabolt (multiple options available) Steerer Diameter: 1.5" tapered Air Spring: Float EVOL Damper: FIT4 2-Position Remote with adjustment Remote Included: No, available separately Travel: 100mm Brake Rotor Compatibility: 160mm Direct Post Mount (27.5" Option up to 180mm compatible; 29" Option up to 203mm compatible) Starting Weight: 1387gTechnologies: Factory Series: “Factory” says it all - feature-packed and designed to exceed the demands of Factory-level riders. What we sell is what they race. Factory Series products feature slippery smooth, ultra-durable Genuine Kashima Coat. Adjustments: Two on-the-fly compression damping positions Open, Firm. Additional low-speed compression (Open mode adjust) 22 clicks. Low-speed rebound 10 clicks. Lightweight FIT4 Closed Cartridge System: Lightweight version of Fox Suspension's patented FIT4 closed cartridge system. The weight-optimised design uses a detailed aluminium piston, intricate material removal and consolidated parts design to make it lighter. Narrow Chassis: The chassis is 10mm narrower than the typical 32 design. Shorter Upper Tube Length: The shorter upper tube length raises the floor of the magnesium lower leg, creating a hollow lower section and a lighter overall system.Manufacturer's Part Numbers: 910-21-041 Black 27.5" KB100 100mm 44mm 910-21-040 Black 27.5" KB110 100mm 44mm 910-21-038 Black 29" KB110 100mm 44mm 910-21-036 Black 29" KB110 100mm 51mm 910-21-035 Orange 29" KB110 100mm 44mm 910-21-034 Orange 29" KB110 100mm 51mm 910-21-039 Black 29" KB100 100mm 44mm 910-21-037 Black 29" KB100 100mm 51mmBuy Fox Suspension Components from Chain Reaction Cycles, the World's Largest Online Bike Store.

Specifically designed for XC racing, this high-quality suspension fork is part of Fox Suspension's renowned Factory Series with a build that's feature-packed and engineered to exceed the demands of Factory-level riders. It's equipped with an updated chassis that's 15% stiffer than the 32 standard model as well as a revised arch shape that offers improved head tube clearance with shorter rakes. Developed from the ground up to deliver uncompromised cross country racing performance, it's also kitted out with a Float EVOL air spring and a FIT4 3-Position damper for a high level of tuneability and control. Coming complete with a genuine Kashima upper tube coating that's slippery smooth and ultra-durable, this is a great choice of upgrade for dependable front-end suspension performance on the most demanding of racing conditions. Float EVOL Air Spring Returning with the same legendary suppleness and longevity, the EVOL air spring in 34’s now has an enlarged negative air spring to assist with mid-stroke support. The 34 SC also comes with the option to tune the negative air spring with a volume spacer. FIT4 3-Position Damper In its fourth generation, Fox Suspension's patented FIT4 closed cartridge system provides three on-the-fly compression damping positions (Open, Medium, and Firm) to adapt to varying trail conditions. Factory Series forks feature an additional 22 clicks of low-speed compression adjustment in the Open mode, allowing riders to fine-tune their exact damping preferences. Technologies: Factory Series: “Factory” says it all – feature-packed and designed to exceed the demands of Factory-level riders. What we sell is what they race.

Additional low-speed compression (Open mode adjust) 22 clicks, Low-speed rebound 10 clicks. 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. 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. The all-new 34 pulls out all the stops, shaving every possible gram while making sure not to compromise the stiffness or strength requirements of modern trail riding. Modern frame designs and geometry trends require modern suspension design solutions. The arch design is designed to pair perfectly with modern trail 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 modelling techniques helped us to create an organic lower leg shape that optimises stiffness with the absolute minimal amount of material.
