Helm 29 Boost Fork
The Helm 29 Boost Fork represents Cane Creek's foray into the high-end fork market, and is designed for discerning riders wanting a stout, highly-adjustable alternative to the other big brands on the market. With a variety of smooth travel options ranging from 100mm to 160mm, and burly 35-millimeter stanchions, this fork is plush throughout its stroke and has a stiff chassis that delivers precise tracking in rough terrain, an ideal setup for aggressive riders challenging their limits on technical trails. 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.
You might be wondering what separates this damper from others on the market if it uses a similar closed-cartridge design that's used throughout the industry for reasons of fade-free performance and low weight. Well, it mostly boils down to the damper tune that's been honed in-house on the dyno and by its 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 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 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. 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 using two dedicated air chambers is it affords the ability to use one air spring and through the use of travel-adjust spacers, the Helm 29 Boost Fork features adjustable travel, thanks to its two included spacers. This option 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 29 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 upâ€”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.

One Fork to rule all forks
- I've put it through the wringer
- True to size
- 6` 1"
- 173 lbs
Are you a suspension nerd? Do you miss the old days when you could change the negative and positive air chamber before all these solo air systems came out? If you answered yes to either of the questions then this is the fork for you! I have had a helm for over a year in both the 29 and 27.5 variations and have tried going back to RockShox and fox after riding it and just cannot. If you can confidently tune your suspension then you will love this fork. A huge pro of it is the fork can range from a 170-130 without needing to change and oils and mess with buying new air spring to change the travel. Cane Creek sends 4 red 10mm tokens that are easily added or removed to be able to change the travel to whatever length you would like. If that doesn't peak you interest one of the other really cool features of this fork is the ability to internally change the progressiveness of the air spring without having to deal with buying tokens. The system is right underneath the air spring valve and can get a better adjustment as compared to the one sized volume spacers that RockShox uses. All in all, after riding this one I don't see myself every purchasing fox or RockShox forks in the near future and in fact Cane Creek just released the MKII of this fork and as soon as I saw the announcement put in an order for the new version to see what upgrades they make to an already incredible fork

The Unicorn you've been looking for!
- I've used it several times
Well you've found it! This is probably one of the most versatile forks you will currently find on the market. What makes it so versatile you ask well it's quite simple actually. Adjustable Length, adjustable negative chamber and no need to buy air tokens it as it all! I've ridden this fork on three different bikes in the last three weeks. I've ridden on the Ibis Ripley as a 140mm, the Yeti SB100 as a 120mm and just last weekend on my HD5 as a 150. On each bike it performed flawlessly and has some of the best small bump compliance in the business. I throw it on my wife's bike who likes a bit softer of a ride and I simply adjust the negative chamber for her. The fork comes with everything you need to adjust travel minus the tools. A 13mm, 19mm and 22mm wrench and you can change the travel yourself in about 5 minutes with a little practice. Service intervals fall in line with Fox, Rockshox etc.. What stands out on this fork is the attention to detail and ease of use. All the knobs are precisely machined and have positive clicks. Want to change an air token, remove the air cap, spin wing nut, move the ramp control disc and spin the wing nut back down. Takes about 5 minutes and you don't need any additional parts. Sag setup is also quite simple. Pump the fork up to about 1/2 your weight, equalize the negative chamber by pushing in a presta type valve on the bottom of your fork and that's it. (well as long as it's in your sag range) My only real complaint is the D-Loc axle (not shown but does come with fork) Nothing wrong with it, it quick and easy to use but I would simply prefer some threads. Pros: Excellent Small bump Compliance Adjustability Bang for your buck Cons: D-Loc Axle no 37mm offset for the new crop of 27.5's does not come with a fender
