we had a park crank puller that destroyed a crank the first time it was used. if i recall, we took measurements on it and the total diameter was slightly undersize. this caused the threads to not fully engage and it pulled the threads out of an old rx100 crank. park said the tool was within their tolerance range so we just threw it away in favor of a campagnolo puller.

our park campagnolo lock ring tool is also a little soft. it looks years and years older than our campagnolo made tool that has been used much more (the campagnolo still looks new)
