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 120mm to 130mm of travel. The boost 110mm 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. - 15mm thru-axle with 110mm Boost spacing - Post-style brake mount - 1.5" tapered carbon steerer - Two sets of Three-Pack mounts - ASTM Condition 3 - For rough off-road riding and jumps less than 24"

ENVE's Road Fork is the fork by which all others are judged, built for road cyclists looking for the optimal balance of weight, strength, and stiffness. When everyone was turning away from the fork aftermarket, we focused our efforts on creating the best aftermarket fork we could. By following our mantra of functional simplicity, we developed a manufacturing process that allows the fibers in an ENVE fork to run continuously from the top of the steerer to the bottom of the drop-outs. The ENVE forks feature a hollow one-piece design free of bonding or drilling, and the brake bolt hole is molded into the crown, allowing for additional weight savings and strength. You can literally put an ENVE fork on a bike within minutes of it leaving the mold. While this manner of construction is novel, the real win is that the majority of artisan frame builders and customers choose ENVE as their fork of choice due to its confident on-road performance and handling characteristics.
