Fox Suspension 34 Float SC Factory Fit4 ForkPart of Fox Suspension's legendary Factory Series, this cross country (XC) suspension fork includes the best-of-the-best technologies and features for tackling the most challenging of XC racing conditions. Developed to exceed the demands of Factory-level riders, this model features a genuine Kashima coating on its upper tubes for slippery smooth, ultra-durable performance. Classed as the brand's lightest ever 34 fork thanks to its Step-Cast design, it is specifically developed from the ground up to deliver uncompromised execution with class-leading tuneability, chassis stiffness and strength. Coming complete with a lightweight Float EVOL air spring and a FIT4 damper with three-position adjust, this is a great choice of upgrade for dialling in your favourite settings and enjoying dependable front end suspension that matches your riding style as well as the terrain.XC Racing Fork with Float EVOL Air SpringReturning 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 Damper with 3-Position AdjustIn 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 adjust in the Open mode, allowing riders to fine-tune their exact damping preferences.Features: Upper Tubes Finish: Genuine Kashima Coat Use: Cross Country (XC) Axle: Kabolt 110mm Steerer Diameter: 1.5" tapered Air Spring: Float EVOL Damper: FIT4 3-Position Adjust Max Tyre Size: 29x2.40" Crown Diameter: 58mm diameter crown Brake Rotor Compatibility: 160-180mm Starting Weight: 1496gTechnologies: 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: Three on-the-fly compression damping positions Open, Medium, Firm. 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 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.Manufacturer's Part Numbers: 910-21-053 Black 29" KB110 100mm 44mm 910-21-060 Black 29" KB110 100mm 51mm 910-21-057 Orange 29" KB110 100mm 44mm 910-21-014 Black 29" KB110 120mm 51mm 910-21-013 Black 29" KB110 120mm 44mm 910-21-012 Orange 29" KB110 120mm 51mm 910-21-011 Orange 29" KB110 120mm 44mmBuy Fox Suspension Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
