Quick question for those of you who may know. I have a Trek 5900 from 2001.. It's nine speed Dura Ace all around. Question is this: will a new 10 speed or 11 speed crankset work with the rest of the groupset.. I would stay with the 53-39 set up. I would need a new bottom bracket with external cups also I believe. I would just like to update the look a little. There seems to be some good deals around for cranksets..Thanks for your time and information.
