I have a '03 Cannondale R600 with a Tiagra Front Derailer and Cannondale PX3, 30/42/52 crankset, i want to get rid of the Derailer now and the crankset a little more down the road. I want to upgrade to a ultegra front derailer. Can i just buy the unit and install it? Or will i have compadability issues. Also when i replace the crankset will the same go also. I know i will have to replace the crankset and bottom bracket when i do that one. Any help and info is greatly appreciated. Also can anyone reccommend a good seat.
Upon searching the web i found the Ultegra will only support a max of 52 teeth and the Dura Ace will support up to 53. My Bike has 53 so i guess i am stuck with the better ($44.98 from performancebike.com). My shifters will work ok with the Dura Ace?
The Tiagra shifts lousy, i have had it tuned up and readjusted numerous times, i only have350 miles on it. The Crankset upgrade is for no other reason for now then weight and a slight performance difference.
