James Quigley Posted October 13, 2007 Report Share Posted October 13, 2007 those park tool crank pullers aren't supposed to be used on isis bb's as the bb's have a larger diameter hole, that'll be why it's stuck in there.I use an adapter that came with my bb, but people often use 5p coins.Best bet is get some mole grips and start pulling/turning it out and see if the threads are still okay.

Matthew_Gibson Posted October 13, 2007 Report Share Posted October 13, 2007 Get two bolts the same thread size, thread one on, about 5-6mm, the thread the second one down so it hits the first one, them tighten the two together. should work if you can find a bolt the same thread.....Or mole grips???Get two bolts the same thread size, thread one on, about 5-6mm, the thread the second one down so it hits the first one, them tighten the two together. should work if you can find a bolt the same thread.....Or mole grips???
