Fox 36 SL Float Factory GRIP X Tapered Mountain Bike Suspension Fork

Introducing the Fox 36 SL Float Factory GRIP X Tapered Fork, the pinnacle of trail suspension technology engineered for serious mountain bikers who demand both lightness and outstanding performance. Weighing in at an incredibly low 1755 grams for the 29” 140mm GRIP X model, this fork brings an unmatched balance of plushness and responsive steering, allowing riders to tackle technical terrain with confidence and agility. Designed specifically for 120 to 140mm of travel, the 36 SL is an evolution of the classic 36 chassis, refined to deliver superior stiffness without adding unnecessary weight.

Fox has revolutionized trail riding with the 36 SL by offering riders a fork that blends the strength and stiffness of over-forking with the weight savings typically seen in lower travel models. With 20% more torsional stiffness than its predecessor, the 34, and a minimal weight increase of just 100 grams, the 36 SL sets a new standard. Its generatively designed arch and crown maximize rigidity, while strategic cutouts and lightening bores keep the weight down, ensuring that every gram helps you push harder and ride smoother.

Beyond its engineering excellence, the 36 SL features the FLOAT EVOL air spring, which enhances compliance by allowing the air shaft to move independently under bending forces. This innovation results in smoother suspension performance when encountering rocks, roots, or other trail obstacles at speed. The increased bushing overlap of 20mm reduces friction between the stanchions and lowers, further enhancing the fork’s smooth feel and durability. Complementing these features is the GRIP X damper, which offers refined descent control, easy setup, and an accessible firm mode to improve pedaling efficiency without sacrificing downhill capability.

Practical design touches such as inboard bypass channels reduce friction by relocating oil circulation away from load paths, and the inclusion of low profile bleeders and a Shimano cassette tool-compatible air spring top cap make maintenance and tuning straightforward. The 36 SL also supports a robust mudguard mount, keeping your fork cleaner and protected without compromising style or function. Whether you’re charging steep descents, navigating technical trails, or seeking the perfect balance of lightweight performance and durability, the Fox 36 SL Float Factory GRIP X Tapered Fork is built to elevate your ride.
