FAQs
Is this bearing compatible with all 1 1/8-inch headsets?
It is designed specifically for Hope 1 1/8-inch headset systems. Compatibility with other brands is not guaranteed.
Do I need special tools for this?
Yes, a proper headset cup removal and press tool set is recommended to prevent damage to the frame or the new bearing.
How often should I replace my headset bearing?
Replacement intervals depend on riding style and conditions, but you should inspect them annually or whenever you feel resistance in your steering.
Can I lubricate the inside of the cartridge?
These cartridges are sealed. While you can apply a light film of grease to the external contact points, do not attempt to open the sealed cartridge itself.
What does the MPN HS123 signify?
HS123 is the specific manufacturer part number for this Hope 1 1/8-inch replacement bearing, which helps in verifying you have the correct item for your headset.
Troubleshooting
Steering feels 'notchy' or stiff after installation
Check that the headset is not over-tightened and that the bearing is seated perfectly level in the cup.
Clicking sound while riding
Ensure the bearing is fully seated and the headset adjustment is tightened to the manufacturer's recommended torque.

Setup, Compatibility & Care
To install this cartridge, you will need a standard headset press and basic hand tools to remove the crown race and upper assembly. Compatibility is limited to 1 1/8-inch headset standards; verify your frame's head tube specifications before purchase. For care, keep the bearing area clean by wiping away excess debris after muddy rides. Avoid using high-pressure water cleaners near the headset, as this can force moisture and dirt past the seals, leading to premature wear. Periodically apply a thin layer of high-quality waterproof bicycle grease to the contact surfaces to ensure a quiet, friction-free operation.
