No.9 MTN Boost ST

A thoughtful complement to our No. 9 MTN Boost LT Fork, this short-travel beauty is just the ticket for transforming hardtail racers into full rigid cross-country champs. Lighter and stiffer than a suspension fork, the MTN Boost ST Fork is long enough to replace forks with 110–120mm of travel. Its Boost 110mm spacing means easy compatibility with a variety of wheelsets, and clearance for 29 x 3.0” or 27.5 x 3.0” tires allows you to switch things up depending on the day.​
