I recently acquired a 10 year old Cube Acid MTB which I intend to refurbish and convert to an ebike.
I need to remove the crankset and purchased a crank puller.
It seems to be a universal size but the "internal" bolt which should push against the bottom bracket spindle to release the crank arm seems too thin, and just slots straight inside the bottom bracket hole.

Are there other sizes/types of crank puller?
