Lightweight Fulcrum Hubset for Modern Boost MTBs.

The Fulcrum MTB Hubset with Straightpull spoke mounts and 28 holes is the ideal basis for a light, stable wheelset on your cross-country, trail or all-mountain bike. With Boost dimensions 15x110 mm (front) and 12x148 mm (rear) as well as Centerlock disc brake mounts, the set is perfectly matched to current MTB frames and forks.

The lightweight front and rear hub bodies in white with black decals provide a refined look and blend in perfectly with modern frame designs. Thanks to straightpull spokes, stiff, precisely running wheelsets can be built, which also impress in tough off-road use. The Shimano HG freewheel makes the rear wheel compatible with common 8–11-speed MTB cassettes (and many 12-speed HG systems, depending on the manufacturer's specifications).

Weighing only approx. 145 g (front) and 267 g (rear), the hubset is very light and is particularly well suited for high-quality custom wheel builds. The included Centerlock lockrings with external teeth facilitate the mounting of disc brakes with a standard Hollowtech II tool.
