Koozer XM490 Quick Release Bicycle Hub 32 Hole

The Koozer XM490 Mountain Bike Quick Release Hub Set is a 32-hole, aluminum alloy front/rear hub pair designed for lightweight MTB wheels and Shimano HG 8–11 speed drivetrains, making it a versatile choice for modern wheel builds. It uses 5x100 mm QR on the front and 5x135 mm QR on the rear, features a 6-bolt disc rotor mount, and relies on sealed cartridge bearings for smooth rotation and reduced maintenance. The Hyperglide (HG) freehub is compatible with standard Shimano freehub bodies, and the hub is SRAM 8–10 speed compatible as well, enabling mixed drivetrain configurations. Commonly used in cross-country, trail, and all-mountain builds, this hub set supports wheel builds, drivetrain upgrades, and replacement of worn hub assemblies for riders who prefer quick-release skewers and disc brakes.
