I have Chorus 8-speed on my ~1998 steel bike, with front sprockets 52 and 39 teeth and a brazed-on front derailer, and a 26-tooth gear in back I'm trying to figure out how to change to a compact crankset for lower gearing. My questions are:
1. Are compatible compact cranksets available for this bike?
2. Would I need to change the front derailer? If so can I use the same braze, or would I need to go to a ring mount?
Thanks for any advice.
