Helm Mark II Air Sprung Fork

The original Helm fork impressed many riders with its stiff chassis, supportive feel, and a host of innovative features. It was a fork that liked it rough and performed best at high speeds under hard-charging riders.

The Mark II retains many of the great features of the original Helm, but Cane Creek has tweaked, tuned, and improved the damper and air spring to create a fork with the ideal balance of buttery smoothness and support.

The fork is available in both air and coil sprung versions. You are currently looking at the air-sprung fork.

Features:

• Lighter compression tune to improve sensitivity
• New SKF low friction seals
• 2.5wt Motorex damper oil with 11% lower viscosity
• New friction reducing air spring material
• Increased air volume for better traction and suppleness
• New threadless air seal head for easier travel change

Who this for? The Helm is best suited for Trail/All Mountain riding and Enduro racing.

Spring type: This fork uses a manually equalised air spring. This differs from most other forks in that you will need to equalise the positive and negative air springs by pressing a release valve at the base of the fork. This requires an extra step in the setup process but it does provide you with extra potential to tune the fork to your liking by varying the pressure between the two air springs.
