Next level plushness.
There's no getting around the fact that a coil sprung fork is always going to be plusher than an air sprung fork. Given the linear nature of a coil spring and the reduction in the number of friction inducing seals, you wind up with a fork that’s way more sensitive to trail chatter thus offering up a smoother ride. Why don't you see more coil forks spec'd on bikes you might be asking yourself? Good question and the simple answer is there is a weight penalty in the neighborhood of 265 grams (that's about 9.3 ounces) over its air sprung version, also it would be difficult to spec the correct spring rate for each rider since it's not a simple as installing a pump and adding or removing air to achieve the correct sag. However, if you're a discerning rider and could care less about weight and instead prize a superior ride, have a look at the Helm Coil 160 Boost Fork for 29in wheels from Cane Creek and revel in its linear spring curve, 35-millimeter stanchions, and refined damper that'll have you mobbing through rough sections of trail in complete comfort while offering a bottomless feel on the biggest drops, berms, and lips in the park.
There's a reason why you see coils almost exclusively on DH bikes and a huge resurgence in enduro. Coils simply keep your tires glued to the trail and does a wonderful job of soaking up rugged trail obstacles. It'll provide more confidence in the rough stuff and offers a wider range of adjustability to tune it to your riding style and terrain. The chassis is the same as the air version giving you the same sure tracking and resistance to torsional twisting, as well as the same closed cartridge mono-tube damper as used on the air-sprung version damper, albeit tuned for a coil spring, with 10 and 17-clicks of high speed and low speed compression and 10-clicks of slow speed rebound.
The Helm Coil 160 Boost Fork is travel adjustable, allowing you to switch between 130 and 160 millimeters of travel, for dialing it in for a particular build or experiment with different ride heights. It's adjustable in 10-millimeter increments by moving the location of the spring perch, otherwise known as the coil piston, on its travel-indexed compression rod. Forks come stock with a 55-pound coil spring that's intended for riders weighing anywhere from 160 to 200 pounds, with 35, 45, and 65-pound alternatives sold separately for lighter and heavier riders alike.
Once you've situated the correct coil spring for your body weight it's time to dial in the sag and Cane Creek makes setup easy with a spring pre-load adjustment on the top left fork leg providing 16 clicks of adjustment. Finally, the Helm Coil 160 Boost Fork comes with a 15 x 110-millimeter D-Loc thru-axle, which slips into a set place with a locking latch on the other side preventing it from going anywhere, as well as an adjustment ring for setting the lever's tension.
