Bicycle Bottom-Bracket Socket with Retaining Assembly

A bicycle bottom-bracket service tool combining a splined socket with a threaded retaining assembly. The supplier illustrates the retaining rod holding the socket in position while a separate wrench turns it.

Check the tool fit

Compare the socket's spline profile and dimensions, the retaining thread and the required wrench connection with your bottom bracket before ordering. A complete verified compatibility list and retaining-thread specification are not supplied. Universal crankset or bottom-bracket compatibility is not confirmed.

This is a bottom-bracket socket arrangement, not the long-handled external-cup wrench design. Follow your component manufacturer's service instructions and use the correct direction and torque for that component.

Selected set

The selected supplier option is the socket with its retaining assembly shown in the matching product photograph. A separate turning wrench or ratchet, bottom bracket and bicycle are not included. Other comparison tools shown in the supplier's general photos are not part of this listing.
