Helm MKII 29 Chameleon

The Limited Edition Chameleon Helm MKII is available in our 29-inch wheel | 44mm offset platform with Cane Creek’s travel adjustable air spring pre-set at 160mm travel or Helm Coil with travel pre-set at 160mm. Looking to blend into the forest?  This unique earth-toned fork with color-shifting decals is the perfect addition to any custom bike build. Helm Chameleon includes Cane Creek’s bolt-on fender.

TAKE CONTROL ON THE TRAIL

The Works Series Helm beats out the competing fork with a stiffer chassis, giving riders more control through chundery sections of trails and rock gardens. This fork is the perfect do-all for riders who regularly ride XC and occasionally rip on more technical and challenging terrain.

HAND-BUILT IN WESTERN NORTH CAROLINA

Every single Helm fork is designed, built, inspected, tested and packed by a dedicated team of suspension professionals at our facility in Fletcher, North Carolina. Our suspension team’s attention to detail is illustrated in our three step Dyno testing, ensuring that our hand built products reach high standards of precision and performance.

This process includes: 

  • Individual Damper Assemblies compression and rebound verification.
  • Helm Chassis validation of the spring and damper
  • Final hand dyno to ensure quality and supple feel.

Nice fork, but don’t care for neg chamber filling process. Not sure if or how much air is transferring to the neg side when pressing the valve. Would rather have another shreader valve to fill the chamber.

Soft paint finish on lowers mars and scrapes far to easily, otherwise this fork is flawless. Dampening works as advertised and it is very versatile and user friendly. I would buy another.

Look great and match my color scheme! Sadly the “E” didn’t come off on one side which made it a lot harder to put on and ended up with a wrinkle in it. All in all, it was probably my fault but it did get slightly messed up
