No.9 MTN Boost LT

For carving XC courses, going the distance on gravel roads, or roaming along bikepacking routes, the Whisky No.9 MTN Boost Fork brings a new dimension to your mountain bike. Lighter and stiffer than a suspension fork, it’s long enough to replace forks with 120 mm to 130 mm of travel. The boost 110 mm spacing means your current wheels will likely bolt right in, and clearance for up to a 29 x 3.0” or 27.5 x 3.0” tire lets you alter your setup for wherever you’re riding. The Three-Pack mounts handily hold extra water, camping gear, tools, tubes, and more.
