Fox 32 Factory Stepcast GRIP SL (2025)

ABSOLUTE LIGHTEST IN XC. MADE FOR MARATHON.

At under 1300g, the 32 Step-Cast is the lightest MTB fork and made for marathon racing. With a sleek reverse arch, this fork also gains 40% stiffness over its predecessor. Available in 100mm travel only.

GRIP SL
The GRIP SL is an incredibly light, short travel-specific damper that not only saves weight, but provides an unparalleled ride feel in its class. Riders experience a supple stroke in the early stages of the travel with an optimized pedal-to-bump efficiency as well as a smooth blowoff force in lockout mode to reduce rider fatigue.

REAR ARCH MATRIX
The rear arch matrix was generatively designed to increase stiffness by 40% while minimizing the weight penalty. With 100mm of travel in the 32 Step-Cast, the rear arch has all the necessary clearance for XC frames.

KABOLT SL AXLE
The svelte new Kabolt SL thru-axle drops an additional 12g over our standard Kabolt axle by eliminating the additional weight of an axle nut and decreasing the flange diameter.

REDESIGNED CROWN
A new 7000 Series aluminum, zero-offset crown supports angled upper tubes, rather than relying on extra material to achieve rake overall rake. The crown not only contributes to the 32 Step-Cast’s stiffness, but when combined with our ultra-light steerer tube, saves approximately 20g over the previous model.

GRIP SL Remote
The GRIP SL is an incredibly light, short travel-specific damper that not only saves weight, but provides an unparalleled ride feel in its class. Riders experience optimized pedal-to-bump efficiency with the convenience of handlebar-mounted remote switch to activate firm mode.
