If youv got a freewheel tool it, then do this! Get a quite long bolt through where the bb goes and put a bolt on the other side, holding the bb tool up against the freewheel. Make sure the bolt isnt tight, so the freewheel has somewhere to move! Put it in a vice, crank side down (you may need sometrhing to stop em from marking if your bothered) take your pedal off and find something like a scaffolding pole, bosh it over the end of your crank arm, and get about 2-3 people swinging from the end of the pole, works everytime for me! Oh and youl need a good vice, as the one i have at hime bends and turns when i do this! Owen
