Full details
This Shimano CUES FH-QC400-HM rear hub is designed for cyclists seeking a reliable and durable component for their disc brake equipped bicycles.

FAQs
What type of cassettes can I use with this hub?
This hub features an HG spline freehub body and is compatible with Shimano HG-style cassettes ranging from 8 to 11 speeds.
Do I need special tools to install a brake rotor?
Yes, for the Center Lock mount, you will need a Center Lock specific lockring tool, similar to a cassette lockring tool.
Can I use this hub on a frame with a 142mm thru-axle?
No, this hub is designed specifically for a 135mm Quick Release axle and is not compatible with thru-axle systems.
How often should I service the bearings?
The FH-QC400-HM uses sealed cartridge bearings. Regular cleaning of the exterior is advised. Bearing service is typically only needed if you hear noise or feel roughness, which should be performed by a bike mechanic.
What is the difference between Center Lock and 6-Bolt brake mounts?
Center Lock uses a splined interface with a lockring to attach the rotor, offering a simpler and often more secure mounting system. 6-Bolt uses six individual bolts to secure the rotor.
Can I convert this hub to a different axle standard?
This specific model is designed for 135mm Quick Release. Conversion kits are generally not available for this type of hub.
Troubleshooting
Cassette does not engage or slips
Ensure the cassette is correctly seated on the HG splines and the lockring is properly tightened. Verify you are using a compatible 8-11 speed cassette.
Brake rotor does not mount securely
Confirm that your brake rotor is a Center Lock type. Ensure the rotor's splines align with the hub's splines and the lockring is fully tightened.
Hub feels rough or noisy
This typically indicates a need for bearing service. Due to the sealed cartridge bearings, it's recommended to have a qualified mechanic inspect and replace them if necessary.
Wheel is loose after tightening quick release
Check that the quick release skewer is properly seated and that the frame dropouts are clean. Ensure the quick release mechanism is functioning correctly.
