The Shimano FH-QC400 freehub body serves as a replacement component for FH-QC400-HM and FH-QC400-HM-B disc brake rear hubs. It integrates with both quick release and 12 mm E-THRU axle systems, supporting the CENTER LOCK and 6-bolt rotor mounting standards used on these hubs. The steel construction maintains consistent power transfer during sustained pedalling efforts.
Drivetrain compatibility covers 11, 10, 9, and 8-speed Hyperglide (HG) cassettes, making this freehub body a straightforward service part for riders maintaining existing Shimano hub systems. Labyrinth+Contact or Contact seals help shield internal components from dirt and moisture, supporting reliable shifting performance over time without frequent maintenance.
