Helm Coil 29 Boost Fork
Designed for the aggressive rider tackling everything on the mountain and launching hits in the bike park, the Cane Creek Helm Coil 29 Boost Fork provides increased mid-stroke support and a more linear spring curve than its air-sprung brethren, although with a weight penalty in the neighborhood of approximately 265 grams (that's about 9.3 ounces). It retains the 35-millimeter stanchions of the air-sprung version, so you'll enjoy its stiff tracking through rough sections of trail and composed feel on bigger features in the park.
You'll immediately notice it rides slightly higher than a comparable air-sprung fork, providing a more natural feel as it tracks over rugged trail surfaces. It also keeps you in a more upright position as you plunge into steep, formidable descents with less brake dive when it's time to keep your speed in check. In fact, Cane Creek uses five millimeters less sag than the air-sprung version of this fork, since it rides higher in its stroke and doesn't need the extra sag to be more supple and supportive.
The Helm Coil 29 Boost Fork is travel adjustable, allowing you to switch your travel in 10mm increments with no additional parts required, depending on the build or riding application you desire. You can adjust the fork in 10 millimeter increments by moving an internal coil piston, no specialized tools needed. Stock forks include a 55 pound coil spring that's intended for riders weighing anywhere from 160 to 180 pounds, though you'll find 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, Cane Creek places a spring pre-load adjustment on the top left fork leg, which provides 16 clicks of adjustment. You'll find the same closed cartridge mono-tube damper used on the air-sprung version providing you with both high and low-speed compression tuning, as well as low-speed rebound adjustment. Additionally, the Helm Coil 29 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.
