A tough, low-maintenance rear hub built to keep trekking, commuting and entry-level mountain bikes rolling smoothly for the long haul. The Shimano FH-QC400-HM-B pairs sealed cartridge bearings with a Centre Lock disc mount and a wide-range HG Spline freehub, so it handles modern 8-, 9-, 10- and 11-speed drivetrains without fuss.

Highlights

  • Smooth, long-lasting rotation from sealed cartridge bearings with high-quality contact seals
  • Fast, secure rotor swaps thanks to the Centre Lock spline mount and lock ring
  • Wide drivetrain coverage: works with 8/9/10-speed and MTB 11-speed HG cassettes
  • Durable build with a lightweight aluminium hub body and steel freehub internals
  • Quick-release axle for tool-light wheel removal

Built to last

The aluminium hub shell keeps weight down while the steel freehub body and pawls stand up to everyday drivetrain loads. Cartridge bearings with contact seals lock out water and grit, so the hub stays smooth through commuting, touring and trail miles with minimal upkeep.

Centre Lock convenience

The Centre Lock interface mounts your disc rotor with a single splined lock ring instead of six bolts, making fitting and removal quicker and the rotor mounting more secure.
