SRAM 746 X7 6-Bolt Disc 32H 12x148mm Boost Rear Hub with XD 11/12 Speed Driver Body

The SRAM 746 X7 Boost Rear Hub is a unisex mountain bike rear hub made for 29er and trail wheel builds using Boost rear spacing, a six-bolt rotor, and SRAM XD cassettes. The 746 hub uses a 12x148 Boost axle format, a 32-hole shell, six-bolt disc mounting, sealed cartridge bearings, and an XD driver body for compatible SRAM 11- and 12-speed mountain cassettes. It is a practical replacement or build hub where those standards already match the frame and drivetrain. Confirm spoke count, axle standard, rotor interface, and cassette driver before building the wheel. It is intended as a straightforward, serviceable component that fits naturally into a well-sorted setup, with compatibility and installation details worth confirming before use.
