Product Information
Full details
The Shimano Tiagra HB-RS470 front road disc hub is designed for cyclists seeking a reliable and good-value option for their disc brake-equipped road or gravel bike. Its key benefit lies in its durable construction and smooth-running bearings, providing consistent performance. A caveat is that the axle and lockring are sold separately, requiring additional purchases for full functionality. This hub features a cold-forged aluminum shell, high-quality cup and cone bearings with a grease sleeve, and a special Boron Nitride machining process for enhanced rotation. It accommodates 28 spokes and is designed for 12x100mm thru-axle forks.

FAQs
What is the difference between Centre Lock and 6-Bolt disc brake mounting?
Centre Lock uses a splined interface similar to a cassette, secured by a lockring. 6-Bolt uses six individual bolts to attach the rotor directly to the hub.
Do I need a special tool to install the disc rotor?
Yes, a Centre Lock lockring tool, typically similar to a Shimano cassette lockring tool, is required to install or remove the rotor.
Can I use this hub with a quick-release skewer?
No, this hub is specifically designed for a 12x100mm thru-axle and is not compatible with standard quick-release skewers.
What is the bearing type used in this hub?
This hub uses Shimano's reliable cup and cone bearing system, featuring high-quality sealing and an internal grease sleeve.
What is the Boron Nitride machining process?
It is a specialized manufacturing process applied to the hub cones that creates an exceptionally smooth surface, reducing friction and improving bearing rotation.
Is the axle included with the hub?
No, the axle is not included with the Shimano HB-RS470 hub and must be purchased separately.
What is the hub's Old (Over Locknut Dimension)?
The Old for this hub is 100mm, standard for 12x100mm thru-axle forks.
Troubleshooting
Hub feels rough or stiff when rotating
This often indicates that the bearings need adjustment or re-greasing. It is recommended to have a qualified bicycle mechanic service the bearings.
Disc rotor is loose or making noise
Ensure the Centre Lock lockring is properly tightened to the manufacturer's specification using the correct tool. If the lockring is damaged, it needs replacement.
Axle doesn't fit or is difficult to install
Verify that you are using a 12x100mm thru-axle compatible with the hub. Ensure there is no debris in the hub's axle interface or the frame's dropout.
Hub is noisy (clicking or grinding)
This could be due to contaminated bearings or issues with the freehub mechanism (if applicable to the rear hub, though this is a front hub). Clean the exterior and consider bearing service if the noise persists.

Setup, Compatibility & Care
Setup: This hub requires a compatible 12x100mm thru-axle (sold separately). The Centre Lock rotor must be installed onto the hub's splined interface and secured with the corresponding lockring (sold separately). Ensure the rotor is tightened to the manufacturer's recommended torque. Wheel lacing should be done by a qualified wheel builder, considering the 28-hole drilling and compatibility with aero or standard spokes.
Compatibility: The HB-RS470 is designed for frames and forks with 12x100mm thru-axle spacing. It uses the Shimano Centre Lock standard for disc rotor mounting. It is compatible with 8, 9, 10, and 11-speed drivetrains when building a suitable wheel.
Care: Regularly clean the hub exterior with a damp cloth. Avoid high-pressure washing directly at the hub bearings. Periodically, the cup and cone bearings may require adjustment or re-greasing. Consult a bicycle mechanic for bearing service, as specialized tools and knowledge are needed for proper adjustment and re-greasing to maintain smooth rotation and bearing life.
