Thanks for the feedback! My experience is getting 50% success with a cheap puller I bought and 50% with a more expensive 3 jaw puller I borrowed from an auto parts store. In the latter case I broke the other bearings I tried to get off. This may be operator error and they also were 32mm bearings. However, I got this bearing separator and puller set and found it easy and effective. It let me remove the inner race left from the bearing I broke as well.
More related to the original thread, if you haven’t seen already dmacuni reported that freewheel hubs are now available at the unicycle.com UK site, including a version compatible with a disc brake! I think you really need an inside disc brake for a freewheel unicycle vs. outside.
