The lightest 34mm fork ever created, engineered specifically to dominate modern XC courses with a perfect balance of surgical steering precision and weight-saving Step-Cast architecture.

Best Use

• XC Racing: The definitive choice for competitive cross-country riders where every gram counts on the climbs.
• Downcountry Riding: Ideal for short-travel bikes that need a stiffer 34mm chassis without the weight penalty of a trail fork.
• Technical Climbs: Perfect for riders who prioritize pedal-to-bump efficiency and a rock-solid lockout for fire-road sprints.

Pro Setup Layout

Designed as the centerpiece of a high-performance racing rig. For the best setup, utilize the FLOAT EVOL air spring to set your sag based on your riding weight, then use the 3-position on-the-fly lever to switch between Open (descents), Medium (technical climbs), and Firm (sprints). The 44mm offset is optimized for modern slack head angles, providing stable handling at high speeds while maintaining agility in tight switchbacks. Use the included Kabolt axle to secure your wheel for maximum lateral stiffness.

What This Product Does

The 34 Step-Cast (SC) provides a rigid platform for 120mm of travel using a unique narrow chassis. The "steps" in the lower legs allow for a narrower crown and arch, shedding massive amounts of material while maintaining the stiffness required for hard cornering. Inside, the GRIP SL damper provides a supple initial stroke and a smooth blowoff force in lockout mode to prevent rider fatigue during unexpected impacts.

Compatibility Check

This fork works IF:

• Your Wheel: Is 29 inches with a Boost 15x110mm hub standard.
• Your Frame: Has a tapered headtube and is designed for 100mm–120mm travel forks.
• Your Brakes: Are disc-only (standard post-mount).

This fork is NOT for:

• Enduro or Freeride: The lightweight Step-Cast chassis is not rated for long-travel, high-impact gravity riding.
• Non-Boost wheels (15x100mm) or older 27.5-inch frames.
• Riders seeking a "plush" downhill feel; this is a race-tuned, firm, and efficient XC tool.

Benefits

• Ultra-Lightweight GRIP SL Damper: A travel-specific damper that saves significant weight while offering three distinct compression modes.
• Kashima Coating: The genuine gold surface treatment on the upper tubes reduces friction and increases seal life.
• Forward-Arch Design: Provides ample headtube clearance at full compression, even on modern frames with oversized profiles.
• FLOAT EVOL Air Spring: Automatically balances positive and negative air chambers for a smooth, predictable feel.

Decision Shortcut

If you are an XC racer looking for the lightest possible fork that doesn't flex under braking or through rock gardens, the FOX 34 Step-Cast Factory is the industry benchmark.

Technical Reality Check

This is a Step-Cast (SC) Specialized Fork. The narrow stance means it has a maximum tire clearance of 2.4 inches. Additionally, because it uses the ultra-light Kabolt bolt-on axle, you will need a 6mm hex wrench to remove your front wheel; it does not feature a tool-free quick-release lever.
