Ceramic bearings for spools, compatible with numerous models such as the 24 Steez and Steez CT. This is a set including bearings and small O-rings, which are not currently sold separately, so how about it for those looking for them? While the effect can be achieved by replacing only the spool side, I believe that the spool performance can be maximized by installing it together with the ceramic double bearing for the palming cup side, which I sell separately.
