Helm 120 Boost Fork

Cane Creek's Helm 120 Boost fork is a stout trail bike fork offering a high-degree of adjustability and a stiff chassis that tracks well over rough terrain. It's an ideal companion for discerning riders looking for a fork that can be tuned just how you like it for any terrain or riding style. Whether you're looking for ultimate plushness on fast trails littered with rocks, or a more supportive setup that encourages popping and jibbing, the Helm delivers on all fronts while doing an impressive job resisting torsional flex during repeated high-speed hits and hard cornering.

One question we had in mind when we heard Cane Creek was entering the fork business is whether or not they'd implement a twin-tube damper like the one found on their acclaimed Double Barrel rear shocks, but after 5-years of development Cane Creek found that a mono-tube damper is more effective for ease of service, weight savings, and reliability reasons. What separates this damper from others on the market is that it's been honed in-house on the dyno and out on the trail by Cane Creek's crew of in-house rippers and sponsored riders. Cane Creek realizes that no two rides or riders are alike, so this damper gives you the wide-ranging ability to tune 10 and 17 clicks of high and low-speed compression, with an additional 10 positions of low-speed rebound adjustment so you can dial in the ride to your terrain, style, and weight. In addition, the fork's air spring has independent positive and negative chambers that allow you to tune the fork for a super supple initial stroke, or for a more supportive overall ride quality.

While some brands used to offer dual-air chambers as a means of further adjustment and the ability to tweak how plush the fork felt off the top of its stroke, many have abandoned it in the name of simplicity and cost savings. We've been fans of it for years and are sad to see it go, so it's refreshing that Cane Creek decided to use independent positive and negative air chambers allowing the rider to adjust the pressure in each chamber. It's done by simply depressing a valve to equalize both chambers, then adding or removing pressure in the positive chamber with your shock pump to get the fork to its desired ride feel. Or you can simply equalize the chambers at the beginning of your ride for a balanced overall feel. While this is a little fiddlier set-up than forks with self-equalizing chambers, it's a welcome feature for the discerning rider wanting to fine-tune every last detail in their fork's operation.

The other advantage of the Helm is that it can the travel is easily adjusted using travel-adjust spacers, allowing you to adjust the travel anywhere from 100 to 160 millimeters. This fork comes stock with 120mm of travel, but this feature gives riders leeway in adjusting the handling and geometry of their current build, or if you build up a shorter or longer travel rig down the road and want to take your fork with you.

Last but not least, the Helm 120 Boost Fork allows riders the ability to tinker with the progressiveness of the air spring by re-adjusting an indexed rod and its static piston assembly. Removing this assembly and adjusting the piston up or down effectively changes how the fork ramps up—all without adding volume spacers like you've come to expect with other forks. This gives you the ability to gain the progressive ramp-up desired for taking bigger hits and rallying across rock gardens without messing with volume spacers.
