Shimano XTR HB-M9210-B Disc Hub Description:

The Shimano XTR HB-M9210-B Disc Hub combines durability, lightweight, and easy serviceability together in an attractive and high performance package. A stiff aluminum hub shell features widely spaced hub flanges that will improve the spoke bracing angle for better ride quality and wheel strength. Inside, the sealed cartridge bearings have an optimized seal design for less rolling resistance and great protection from the elements, and those bearings roll on an axle that has preload adjustability so the rider/mechanic can dial in the bearings for optimal performance. The Microspline freehub in the rear hub rapidly engages to provide effortless acceleration and to make it much easier for a rider to maintain their momentum when tackling uphill and/or technical sections of the trail. Multiple options for spoke count and an easily serviceable design round out the features of these lightweight and high performance hubs.

Features:

• Microspline freehub features 3.5 degrees of engagement for rapid acceleration and an easier time positioning the pedals going over obstacles and when pedaling uphill
• Optimized seal design on the cartridge bearings reduces rolling resistance and keeps the elements from getting inside
• Boost spacing spreads the hub flanges out for a better spoke bracing angle for better wheel durability, lateral stiffness, and ride quality
• Thru axle design makes it very easy to repeatedly install wheel into the frame or fork so the rotor clears the brake pads and disc brake caliper and will significantly improve the stiffness at the dropout
• Centerlock disc rotor interface on the hubs creates a secure rotor attachment and reduces the weight of the wheels
• Adjustable preload enables the rider/mechanic to fine tune the tension on the hub bearings for optimal performance
• Easily serviceable/replaceable cartridge bearings extends the useful life of the hub
