Does the front derailleur have limits to which size chain rings can be used?
I have a groovy old 1988 Schwinn Prelude and for the most part it does just what I need. However there are some steep sections of excellent paths nearby that are a bit to much. Fitness is decidedly a factor ;)
I currently have a 2x6, I assume stock parts but I cannot be sure. Chain rings are 52-40 and cassette is 14-28. The aggressive old style. There aren't many options for changing the cassette, but I was thinking perhaps I could put a compact or even a gravel/mtb chain ring set on.
I use exclusively the 40t ring. I can count on one hand the number of times I've used the 52t. I mostly commute and go for leisure rides, so the racing set up is impractical. Can I simply switch the chain rings out for a 42-34 for example? Or will the front derailleur be unable to function properly?
The derailleur is mounted with a bolt on band so it is maybe possible to lower it on the seat tube slightly to accommodate the new rings.
