The Helm MKII is our first major revision of the Helm fork lineup and improves on its predecessor in nearly every way.
The Helm MKII includes a newly designed damper featuring a new compression and mid-valve circuit for increased support and control while a new SKF oil seal head and 2.5 weight damper oil reduce friction and provide a more supple ride-feel.
HELM MKII AIR SUSPENSION FORK
The HELM MKII includes all of the innovative features of the original HELM fork including a tokenless air volume adjustment design, independently adjustable positive and negative air chambers on the air spring and rider-adjustable travel which allows HELM MKII owners to change the travel of their fork at home with just a few common tools.
REDESIGNED AIR SPRING
The air spring has received a significant redesign with a new air piston designed to reduce friction, an increased air volume for better traction and suppleness, and a threadless seal head for easier travel change.
UPDATED DAMPER
The updated damper features a new compression and mid-valve circuit for increased support and control while a new SKF oil seal head and 2.5 weight Motorex damper oil reduce friction and provide a more supple ride-feel
SKF LOW-FRICTION WIPER SEALS
The fork includes low-friction SKF wiper seals on the castings. These seals are typically seen as an after-marketing upgrade on most suspension forks, however they are a stock feature on the HELM MKII.
HELM MKII
The HELM MKII comes in 29/27.5+ and 27.5 wheel sizes with both air and coil sprung versions available. The 29/27.5+ version of the fork is available in 51mm and 44mm offset and is adjustable from 130mm to 160mm of travel while the 27.5 fork is available in 44mm offset only and is adjustable from 130mm to 170mm of travel.
29/27.5+ models of the fork will come in a gloss black finish with matte black stickers and the 27.5 model will come in a matte black finish with gloss black stickers. Aftermarket sticker kits are available in brushed silver and gold.
