Shimano FC-M739-4 chainring compatibility
I have an old mtb equipped with a Shimano FC-739-4 crankset. The middle 32t chainring has some really worn out teeth; the chain starts slipping under very light load. My question is: what are other compatible chainring for this chrankset?
I'm asking this because I did buy a compatible-looking 32t chainring, but it ended up sitting too close to the 3rd ring, squeezing the chain.

Besides the OEM replacement ring I can only suggest trying chain ring bolt spacers to increase the c-c dimension. Andy
