Shimano FH-M9210-B XTR Boost Rear Hub/Centerlock/32H

The XTR FH-M9210-B rear hub offers improved reliability and performance through improved seal design and stainless-steel cartridge bearings with pre-load adjust, creating an easily serviceable and smooth-rolling rear hub. Lighter weight with improved engagement (max 3.5 degrees), FH-M9210-B is available in 12x148 boost spacing and traditional 28H/32H drilled options.

• Quicker Engagement/Less Drag: A 3.5-degree engagement angle makes the FH-M9210-B fast off the line, while smart seal design and smooth bearings mean less drag when coasting.
• Conventional Drilling/Boost Spacing: Available in conventional 148x12 boost spacing and traditional 28H and 32H drilling options.
• Cartridge Bearings: XTR hubs are now available with easily serviceable stainless steel cartridge bearings.
• Rotation: Cartridge bearings, optimized seal designs and preload adjust keep the hub consistently rolling smoothly.
