The Shimano XTR HB-M9110 is a flagship MTB front hub built for demanding trail and enduro riding. Engineered as part of the XTR M9100 groupset, it delivers exceptional stiffness, precise bearing adjustment, and reliable disc brake performance via the Centre Lock rotor interface — all in a lightweight anodised aluminium shell suited to custom 32-hole wheel builds.

Highlights

• Centre Lock disc interface: Spline-mount rotor attachment delivers maximum precision and braking rigidity; faster rotor installation and removal compared to 6-bolt systems.
• Dual labyrinth and contact seals: Layered sealing system keeps contaminants out of the cup-and-cone bearings, extending service life in wet and muddy conditions.
• Refined cup and cone surfaces: Precisely machined bearing surfaces allow fine adjustment of bearing preload for smooth, low-drag rotation across a wide range of conditions.
• 32-hole J-bend spoke design: Standard j-bend compatibility gives maximum flexibility when choosing spokes and building custom wheels.
• Oversized aluminium axle: Stiffened 15mm thru-axle interface improves front-end tracking and steering accuracy.
• XTR M9100 polished grey finish: Anodised aluminium shell matches the wider XTR M9100 aesthetic.

Construction & Bearings

The HB-M9110 uses Shimano's proven cup-and-cone bearing design with stainless steel balls and machined bearing races. Cone wrench flats allow on-trail bearing preload adjustment. The dual sealing system — combining a labyrinth outer seal with an inner contact seal — provides excellent contamination resistance without adding significant rolling resistance.

Compatibility & Fit

This hub is designed for standard (non-Boost) 100mm front fork spacing with a 15mm thru-axle. It accepts 32 J-bend spokes and uses a Centre Lock disc rotor interface. Lock ring sold separately. Suitable for use with Shimano Centre Lock rotors or any Centre Lock-compatible rotor. Note: This hub does not fit Boost 110mm fork spacing — for Boost, see the HB-M9110-B variant.
