Lightweight Fulcrum hub set for modern Boost mountain bikes.

The Fulcrum MTB hub set with Straightpull spoke mounting and 28 holes is the ideal foundation for a lightweight, stable wheelset for your cross-country, trail, or all-mountain bike. With Boost dimensions of 15x110 mm (front) and 12x148 mm (rear), as well as a Centerlock disc brake mount, the set is perfectly suited to current MTB frames and forks.

The lightweight front and rear hubs in white with black decals create a refined look and complement modern frame designs perfectly. Thanks to the Straightpull spokes, you can build stiff, precisely running wheels that also perform reliably in demanding off-road conditions. The Shimano HG freehub body makes the rear hub compatible with common 8-11-speed MTB cassettes (and many 12-speed HG systems, depending on the manufacturer's specifications).

At just approx. 145 g (front) and 267 g (rear), this hub set is very lightweight and particularly well suited to high-quality custom wheel builds. The included Centerlock lockrings with external splines make it easier to install the brake discs using a standard Hollowtech II tool.
