The

is a lightweight mountain bike fork designed for cross-country (XC) and down country riding, featuring a GRIP damper and a distinctive Step-Cast chassis. It is known for balancing light weight with trail-capable stiffness and performance.

Key Specifications

Intended Use: Cross-Country (XC) and cross country riding.
Travel: Typically available in 100mm or 120mm options.
Damper: Features the reliable GRIP damper with 3 on-the-fly compression damping positions (Open, Medium, Firm) and micro-adjustments for low-speed rebound.
Air Spring: Uses the FLOAT EVOL air spring system, which provides plushness off the top, extra mid-stroke support, and tunable bottom-out progression.
Chassis: The Step-Cast (SC) lower leg design is purpose-built for weight savings, using a narrow stance and external "steps" to make room for spokes and the brake rotor while maintaining stiffness.
Axle: Uses a 15mm x 110mm Boost thru-axle (often the lightweight Kabolt axle version).
Stanchions: 34mm diameter stanchions with a black anodized finish in the Performance Series.
Weight: Praised for its low weight, the 120mm version can weigh as little as 1,422g (claimed weight for the factory version with GRIP SL damper).

Reviews and Performance

Stiffness and Weight Balance: Reviewers consistently praise the fork's ability to balance low weight with sufficient stiffness for demanding trails, a key selling point over a standard XC fork.
Supple Feel: The FLOAT EVOL air spring is noted for excellent small-bump sensitivity and mid-stroke support, making for a smooth ride on various terrain.
Damping Performance: The GRIP damper offers reliable performance and easy-to-use three-position adjustments, allowing riders to quickly adapt to changing trail conditions.
Confidence Inspiring: The stiff chassis and effective damping give riders confidence on aggressive, technical descents without feeling overly harsh.

TAILOR MADE FOR THE RIGORS OF MODERN XC RACING

The lightest 34 ever, the 34 Step-Cast is designed from the ground up to deliver uncompromising XC race performance with class leading tunability, chassis stiffness and strength.

LOWER LEG ARCH

The arch design is pairs perfectly with modern trail bikes, where head tube profiles have grown larger and fork offsets shorter. The 34 SC’s arch juts forward to provide ample headtube clearance at full compression. Countless engineering hours created an organic lower leg shape that optimizes stiffness with the absolute minimal amount of material.
