The Fox 32 Step-Cast Factory 29" Fork is engineered to be the absolute lightest in XC, and tailor-made for marathon racing. Weighing in at under 1300g, this fork sets a new standard for lightweight performance while offering enhanced stiffness, agility, and control.
STIFFER = MORE GRIP
Featuring a sleek reverse arch design, the 32 Step-Cast fork delivers a remarkable 40% increase in stiffness compared to its predecessor. This translates to improved handling and responsiveness on the trail, providing riders with greater confidence and control.
GRIP SL DAMPER
The GRIP SL damper is specifically designed for short-travel applications, offering exceptional performance with minimal weight. Riders can expect a supple stroke at the beginning of the travel, optimized pedal-to-bump efficiency, and smooth blowoff force in lockout mode to reduce fatigue during long rides.
REAR ARCH MATRIX
Engineered using generative design principles, the rear arch matrix maximizes stiffness while minimizing weight. With ample clearance for XC frames and 100mm of travel, this fork ensures optimal performance and durability on the trail.
KABOLT SL AXLE
The Kabolt SL thru-axle further reduces weight by 12g compared to the standard Kabolt axle. By eliminating the need for an axle nut and reducing the flange diameter, this sleek design enhances overall efficiency without compromising strength.
REDESIGNED CROWN
Crafted from 7000 Series aluminum, the zero-offset crown of the 32 Step-Cast fork supports angled upper tubes for improved rake and stiffness. This innovative design, combined with an ultra-light steerer tube, results in a weight savings of approximately 20g compared to previous models.
