WHEELS Mfg Ball Bearing Retainer

These retainers are designed for specific standard assemblies. You should verify that your current bearings use a 5/32-inch ball diameter and a 22-ball count retainer. If your existing components match these specifications, these will be a direct replacement.

Yes, these are specifically compatible with the FSA Orbit DL Threadless and FSA Orbit UF Threadless Top headsets. For other systems, you must confirm the ball size and count match your current hardware, as bicycle standards vary significantly.

Bearing grade refers to the precision and roundness of the steel balls, with lower numbers indicating higher precision. Grade 300 is a standard, reliable choice for bicycle headsets and bottom brackets, offering a balance of durability and smooth performance for general cycling.

Yes, you should always apply a high-quality bicycle-specific grease to the bearings and the race before installation. This prevents corrosion, reduces friction, and helps the bearings seat properly for smoother operation.

These retainers are designed for assemblies that specifically use a cage to hold the bearings in place. If your headset or bottom bracket was originally designed for loose ball bearings without a cage, these retainers may not fit correctly and could cause damage.
