Bomber 58 27.5 Air Grip Fork

What Our Gearhead® Experts Are Saying:

"I've run a lot of forks on steep, consequential terrain, and the 40 is in a category of its own when it comes to high-speed composure. The GRIP X2 damper gives you fine-tuned control over exactly how the fork responds to square-edge hits and braking bumps, and the Glidecore air spring keeps the action buttery smooth even when the loads get heavy. If you're building a dedicated DH rig or spending serious time at the bike park, this is the fork."

At the top of a World Cup downhill course, there is no margin for a fork that isn't fully committed to the task. The FOX 40 Float Factory Grip X2 Fork has been the standard at that level for years — trusted by racers when the consequences of suspension failure are measured in hundredths of a second and far more. This generation brings two significant updates that elevate an already proven platform: the FLOAT EVOL GlideCore air spring and a revised GRIP X2 damper, together delivering more traction, more tunability, and smoother suspension action than any previous 40.

The FLOAT EVOL GlideCore spring reduces friction and binding by moving with the fork under dynamic load rather than resisting it — a distinction that translates directly to better wheel contact and more consistent feel through rough, high-speed terrain. The GRIP X2 damper backs that up with the most precise and adjustable compression and rebound control FOX has ever built into a descent-focused fork, capable of handling the broadest range of conditions a DH course or bike park can produce. A generatively designed arch maintains steering responsiveness and line-holding precision, while relocated bypass channels add sensitivity to small trail irregularities at speed. Kashima-coated stanchions and a floating axle round out a fork built without concessions for the most demanding riding on the planet.
