I recently picked up a nice used road bike from eBay. The gearing is kicking my rear. It is a compact double with 39/50 front and 25/12 back. On a climb the slowest i can comfortably pedal is 9mph. Way to much for me. I would like to get something around 5.5-6 for steeper climbs.
First the Group set is a 2006 Dura Ace. Should I drop the front inside ring or change a back ring. Is it possible to change the rings on a cassette? Secondly, what is a good source for buying the appropriate rings?
Thanks in advance.
