Crafted to conquer the demands of modern XC racing, the Fox 34 Step-Cast Performance 29" Fork stands as the lightest 34 yet. Engineered for uncompromising performance, it boasts top-tier tunability, chassis stiffness, and strength. Paired with a GRIP damper, this fork ensures an unparalleled riding experience.

The innovative arch design seamlessly integrates with contemporary trail bikes, accommodating larger head tube profiles and shorter fork offsets. With forward-jutting arches, ample headtube clearance is guaranteed even at full compression. Extensive engineering efforts have resulted in an organic lower leg shape that optimizes stiffness while minimizing material usage.

Featuring the sleek Kabolt SL thru-axle, this fork sheds an additional 12g compared to the standard Kabolt axle. By eliminating the need for an axle nut and reducing the flange diameter, it enhances overall efficiency without compromising strength.
