The Helm MKII is our first major revisionof the Helm fork lineup and improves on its predecessor in nearly every way.
The Helm MKII includes a newly designeddamper featuring a new compression and mid-valve circuit for increased supportand control while a new SKF oil seal head and 2.5 weight damper oil reducefriction and provide a more supple ride-feel.
HELM MKII AIR SUSPENSION FORK
The HELM MKII includes all of theinnovative features of the original HELM fork including a tokenless air volumeadjustment design, independently adjustable positive and negative air chamberson the air spring and rider-adjustable travel which allows HELM MKII owners tochange the travel of their fork at home with just a few common tools.
REDESIGNED AIR SPRING
The air spring has received a significantredesign with a new air piston designed to reduce friction, an increased airvolume for better traction and suppleness, and a threadless seal head foreasier travel change.
UPDATED DAMPER
The updated damper features a newcompression and mid-valve circuit for increased support and control while a newSKF oil seal head and 2.5 weight Motorex damper oil reduce friction and providea more supple ride-feel
SKF LOW-FRICTION WIPER SEALS
The fork includes low-friction SKF wiperseals on the castings. These seals are typically seen as an after-marketingupgrade on most suspension forks, however they are a stock feature on the HELMMKII.
HELM MKII
The HELM MKII comes in 29/27.5+ and 27.5wheel sizes with both air and coil sprung versions available.
