I have a pair of stronglight cranks, so they are french threaded, and i in fact had access to the right tool from my local bike shop, but i guess before i got the bike someone took the cranks off wrong and threaded them. so the right crank puller would not even get them off. i have tried riding around with the crank bolt taken out and have not managed to get the right arm off after riding around for almost 100 miles. right now i am at a loss. i dont know what else i can do to get them off relatively safely without damaging my BB. I do not care about the cranks and would not shed a a single tear if they broke or were ruined as long as i successfully get them off. I would like to do this without ruining my BB. I have read about a tool that can fix the threads, but i dont think that exists, or atleast for french threads. If anyone has any ideas on how to get my cranks off without hurting the bottom bracket, they would be appreciated. thanks
