So, I bought an old cannondale m700 and new it needed parts replaced. 5 bolt chain-rings for the stock CODA crank are nearly impossible to source, so I decided to buy a new crank.

Enter my Shimano FCM311 front crank. I installed it with zero problems. A test ride and no popping, no creaking, no skipping. It is beautiful. But I have hit a snag and it is my chain line. When the shifter and derailer are in 1st the chain is on the 2nd ring, upshift to 2nd and the chain is on the 3rd and upshift again to 3rd and the chain falls off.

I figure I need a new bottom bracket. Any suggestions for a new 68mm BB that will restore my chainline?
