The one by which all others are judged, the Fox 40 Factory mountain bike fork is a true downhill icon, widely regarded as one of the best downhill suspension forks on the market, trusted by the professionals and weekend bikepark riders.

Designed specifically for aggressive downhill and bike park riding, the new 2027 Fox 40 delivers exceptional performance, stiffness, and control on the most demanding terrain. With its dual crown design and premium materials, this fork is engineered to handle high-speed descents, big hits, and technical rock gardens with confidence.

One of the standout features of the Fox 40 downhill fork is its advanced damping system. Equipped with Fox’s updated Grip X2, riders benefit from precise adjustability, including high- and low-speed compression and rebound settings. This allows for a highly tuneable ride, making it easier to optimize suspension performance for different trails and riding styles. Combined with its smooth Kashima-coated stanchions, the Fox 40 provides consistent, predictable suspension feel, helping riders maintain traction and control in rough conditions.
