FAQs
Are these bearings sold in pairs?
This product is typically supplied as a single bearing unit. Ensure you order the correct quantity for your bottom bracket service.
Can I use these in a non-Hope bottom bracket?
No. These bearings are engineered specifically for Hope bottom bracket systems.
Do I need special tools to replace these?
Yes, a proper bearing press and potentially a drift set designed for Hope components are required to avoid damaging the bearing or the cup.
How do I know if my spindle is 30mm?
Consult your crankset specifications or use digital calipers to measure the diameter of the spindle shaft where the bearings sit.
Should I apply grease during installation?
Yes, applying a thin layer of high-quality bike grease to the outer race and the press surface helps with installation and prevents future creaking.
Troubleshooting
Creaking noise during pedaling
Check that the bearings are fully seated and that the cups are properly torqued into the frame.
Increased friction or 'gritty' feeling
The bearings may be contaminated or worn; inspect the seals and consider replacing the bearing set.
Lateral play in the crankset
Verify that all preload spacers are correctly positioned and the crank arm is tightened to the manufacturer's specified torque.

Setup, Compatibility & Care
To install these bearings, you must use a dedicated bottom bracket press tool compatible with your specific frame and the Hope bottom bracket cups. Always ensure that the bearing seats are clean and lightly greased before installation to prevent creaking. Compatibility is strictly limited to Hope bottom bracket systems designed for 30mm spindles; verify your current setup before beginning the installation. For care, avoid high-pressure water washing directly at the bearing interface, as this can force debris past the seals and lead to premature wear. Regularly check for any lateral movement or grinding sensations, as these indicate it is time for a replacement or a service of the sealing grease.
