The Fox 34 Step-Cast Factory 29" Fork has been tailor-made to meet the demands of modern XC racing. Engineered to be the lightest 34 fork ever, it sets the standard for XC race performance with unparalleled tunability, chassis stiffness, and strength.
STIFFER, LIGHTER, MORE GRIP
Designed for optimal performance, the 34 Step-Cast features enhancements that ensure increased stiffness, reduced weight, and improved grip on the trail. Whether navigating technical sections or powering through challenging climbs, the 34 Step-Cast delivers exceptional performance and responsiveness.
GRIP SL DAMPER
The GRIP SL damper is specifically designed for short-travel applications, offering remarkable weight savings without compromising ride quality. Riders benefit from a smooth stroke, optimized pedal-to-bump efficiency, and a seamless transition to lockout mode for reduced rider fatigue during intense races.
LOWER LEG ARCH
The innovative arch design of the 34 Step-Cast complements modern trail bikes, providing ample headtube clearance at full compression. Through meticulous engineering, the lower leg shape is optimized to maximize stiffness while minimizing material, resulting in optimal performance and durability.
KABOLT SL AXLE
Featuring the new Kabolt SL thru-axle, the 34 Step-Cast sheds additional weight by eliminating the need for an axle nut and reducing the flange diameter. This svelte axle design enhances overall performance and responsiveness, ensuring a competitive edge on the racecourse.
