Damn chain line. Yeah, the cranks have about 1-2mm of play in them and the drive train is loud. The new chain probably didn't flush right or something. Hopefully its the cranks. It's going to be awhile before I am comfortable sprinting on the bike again. I just hope the fear of crashing goes away quick. I was going downhill at about 25mph, broke my acromion and surgery consultation next week. Thanks for replies.
