FAQs
What type of disc rotors are compatible with the HB-QC400 hub?
This hub is exclusively compatible with Center Lock disc brake rotors. It does not support 6-bolt rotors.
What is the axle width of this front hub?
The hub has a standard Over Locknut Dimension (O.L.D.) of 100mm and uses a quick release skewer.
How do I maintain the cartridge bearings?
The hub features modular industrial cartridge bearings designed for durability. The rubber contact seals help protect them. Routine care involves cleaning the exterior and ensuring seals are intact. If bearing performance degrades, replacement by a mechanic is recommended.
Does the hub come with a quick release skewer?
Yes, the Shimano CUES HB-QC400 Front Hub includes a steel quick release skewer.
What is the spoke hole count?
The hub is drilled for 32 spokes, a common standard for building durable wheels.
Can I use this hub for mountain biking?
This hub is suitable for general riding, commuting, and light trail use. For aggressive or professional mountain biking, consider hubs designed for higher stress applications.
Is this hub compatible with all disc brake systems?
It is compatible with Shimano hydraulic and mechanical disc brake systems that utilize Center Lock rotors. Ensure your brake caliper and mount are also compatible with the rotor size you choose.
Troubleshooting
Disc rotor is loose or noisy.
Ensure the Center Lock rotor is properly seated and tightened to the hub's locking ring with the correct torque specification using a lockring tool. Check that the lockring is not damaged.
Wheel feels stiff or does not spin freely.
The cartridge bearings may need adjustment or replacement. Inspect for contamination or damage. If contaminated, cleaning and re-greasing might help, but replacement of the cartridge bearings is often recommended for optimal performance.
Water or mud contamination in bearings.
The rubber contact seals help prevent this, but if contamination occurs, the cartridge bearings may need to be replaced. A qualified mechanic can perform this service.
Quick release not tightening securely.
Ensure the quick release skewer is correctly installed and adjusted. Check for any obstructions or damage to the fork dropouts or skewer mechanism.

Setup, Compatibility & Care
Setup:
- Install a Center Lock disc rotor onto the hub body. Ensure it is tightened to the manufacturer's specified torque.
