Target locked on the top step of the podium and developed in the crucible of World Cup competition, the 40 is the definitive DH race fork. FOX's GRIP X2 is the most tunable, supportive, and smoothest descent-focused damper they've created, ensuring the 40 stays planted in the hot seat - GRIP X2 is the most tunable, supportive, and smoothest descent-focused damper FOX has created - Riders reap the benefits of sitting higher in the travel while tires stay glued to the ground, cornering with increased traction, and experience reduced fatigue - Lower leg bleeders allow atmospheric pressure equalization at the push of a button, and the bypass channels increase volume to alleviate pressure ramping as the fork moves through its travel for better fork performance by increasing small bump sensitivity and responsiveness - The lower leg arch design of the 40 maximizes strength and steering stiffness for downhill performance while adding no unnecessary weight - Fitted with the proven and reliable FLOAT EVOL air spring - Floating thru axle allows perfect chassis alignment and reduces unwanted friction between the upper and lower fork legs, providing much smoother suspension movement throughout the entire range of travel - Kashima Coating on upper tubes for added durability
