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

34 is the ultimate trail companion. Featuring an EVOL air spring, choice of dampers, and a lightweight yet robust chassis, you can count on 34 to get up and down the mountain, every time.

In its fourth generation, our patented FIT4 closed cartridge system provides two on-the-fly compression damping positions—Open and Firm—to adapt to varying trail conditions.
Factory Series forks feature an additional 22 clicks of low-speed compression adjust in the Open mode, allowing riders to fine-tune their exact damping preferences.

Upper Tube Finish: Kashima Coat

Rotor Size: 160 direct Post Mount, Up to 203 compatible

Air Spring: FLOAT EVOL

Steerer: 1.5 Taper

Starting Weight 27.5 - 3.50 lb / 1589 g (F-S, 34 SC, 27.5”, 120mm Travel, Kabolt 110, 3Pos-Adj)*

Starting Weight 29 - 3.58 lb / 1623 g (F-S, 34 SC, 29”, 120mm Travel, Kabolt 110, 3Pos-Adj)*

As a fork compresses, the air volume within the lower legs decreases, increasing air pressure. The more the fork compresses, the more pressure increases. This effect can have the unintended consequence of preventing full travel from being achieved. Our lower leg channels help alleviate this issue by dramatically increasing air volume within the lower legs and thereby reducing the amount of additional unintended pressure ramping.

Another benefit of these channels is that lower leg bath oil is circulated to the upper reaches of the lower legs, continuously lubricating the foam rings and bushings as the fork compresses and extends through its travel.

Stiffness-to-weight is the ultimate metric for bicycle design. Engineers invest countless hours poring over every ounce of material in an effort to optimize this critical ratio. The all-new 34 pulls out all the stops, shaving every possible gram while making sure not to compromise the stiffness or strength requirements of modern trail riding.

Modern frame designs and geometry trends require modern suspension design solutions. The arch design is designed to pair perfectly with modern trail bikes. Head tube profiles have grown larger and larger, and fork offsets shorter and shorter. Our new arch shape takes this need into account by jutting forward to provide ample headtube clearance at full compression. State-of-the-art computer modeling techniques helped us to create an organic lower leg shape that optimizes stiffness with the absolute minimal amount of material.

Returning with the same legendary suppleness and longevity, the EVOL air spring in 34’s now has an enlarged negative air spring to assist with mid-stroke support.

New for 2022, the 34 SC comes with the option to tune the negative air spring with a volume spacer.
