Ultimate USE always brings a product to market that is innovative and provides a genuine advantage to the rider. The Helix is no exception. Fundamentally simple, the British made Helix avoids the pitfalls of the air & oil systems currently. Utilising a helical shaft, its clutch is activated with a custom made, “mount anywhere”, remote lever, allowing it to freely rise, fall and lock at any height. Maximum drop of 125mm or 165mm available.
