Chris King R45 / R45D Hubshell Bearing

Yes, these hubshell bearings are designed to be compatible with both the standard rim-brake R45 hubs and the R45D disc-brake models.

These bearings are designed to be fully serviceable, which is a hallmark of Chris King components. While you can perform the maintenance yourself if you have the proper tools and experience, it is generally recommended to have a professional mechanic handle the service to ensure the bearings are seated and adjusted correctly.

You should consider replacing your bearings if you notice increased drag, audible grinding, or lateral play in the wheel while it is mounted on the bike. Regular maintenance can often extend their life, but these symptoms typically indicate that the internal races or balls have worn beyond their effective service life.

These specific replacement bearings are constructed from high-quality steel, consistent with the standard bearings found in Chris King R45 hubsets.

Chris King manufactures these bearings in-house to exact tolerances specifically matched to their hub shells. Using genuine parts ensures the precise fit and seal integrity required to maintain the performance and longevity the R45 system is known for.
