need a snarky comment? SHANTS!!!
as for rotafixing... golly... i GUESS, just MAYBE, MAYBE it would be possible to tweak the procedure JUST a little bit. i mean, I'm not sure if it would even be POSSIBLE to put a handkerchief or a piece of tape on the BB shell so that you don't scratch it... MAYBE. aaaaahhhh, no, i'm not even going to try. who's ever heard of there being even a remote possibility of ever protecting a paint job anywhere on a bicycle???
