HELM Coil 27.5

Select Bike to Check Fit

Coil confidence is being rediscovered by endure riders all over the world. Fork chassis weight and overall bicycle weight has decreased over the last few years, allowing the return of faithful coil sprung suspension products.


Helm Coil is optimized for 130mm to 160mm of travel, with the ability to be internally adjusted by changing the location of the spring perch (coil piston) on the travel-indexed compression rod. This procedure requires no additional parts.



“As soon as we dropped in I was enjoying the supple and responsive feel of the Helm Coil.. Big bump absorption was also impressive, whether taking sharp hits or landing jumps the action was always smooth and linear.” – Steve Fisher / Bike Rumor



A spring is required for this shock. If you have your own, select "I already have a spring", otherwise you can calculate the correct spring and it will be added to your cart along with your shock.
