Helm Air 27.5 forks will have a maximum travel setting of 170mm. Helm Coil 27.5, Helm Coil 29 and Helm Air 29 forks will have a maximum travel setting of 160mm.
Helm Forks are travel adjustable, but are optimized for travel settings between 170mm and 130mm of travel.
Helm Air forks use travel spacers to adjust travel. Two 10mm travel spacers are included with every Helm Air fork. Helm Coil forks are adjusted by changing the location of the spring perch (coil piston) on the travel-indexed compression rod. This procedure requires no additional parts.
