The Shimano Deore XT FH-M8110-B rear freehub is purpose-built for demanding trail conditions and aggressive riding. It’s optimized for 12-speed Micro Spline cassettes, enabling a tighter gear range and faster acceleration. Whether you're tackling steep climbs or descending technical trails, this hub delivers reliable power transfer every time.

Micro Spline Compatibility for Performance Gains: This freehub features a Micro Spline interface that allows the use of a 10T top gear. The smaller spline diameter results in faster pickup and more compact gearing options. The design enhances acceleration, especially useful during punchy climbs or rapid transitions between trail segments.

Boost Spacing for Stability and Rigidity: With a 148 mm O.L.D. Boost spacing, the FH-M8110-B offers better chainline and improved frame clearance. This makes your setup more robust and enhances wheel stiffness, crucial for confident cornering and downhill control. The boost hub standard also ensures compatibility with a growing range of modern mountain bikes.

Effortless Rotor Installation: Thanks to Shimano’s Center Lock technology, installing disc brake rotors is quick and secure. The spline mount with a lock ring streamlines setup and service, while ensuring consistent rotor alignment and braking performance. It’s a system designed for efficiency on and off the trail.

Sealed bearings and Shimano’s proven hub construction offer smooth rotation and low maintenance needs, helping you focus on your ride, not your repairs.
