Hello,
I'm running DA 8spd STI and am hunting for a 39T. I know that there are various versions of 7410 53T
rings, marked 'A', 'B', or even no mark I think. My 53 is the B version with the ramps. I need to
know if all of the 39T DA 8spd rings were the same or if they too came in 'A' and 'B' versions. Mine
is marked Shimano SG, B-39. Since the 39 doesn't have ramps did these ever change over the 7410
years? Should I only hunt for a B-39 ring for best shifting or will any 8sp DA 39 be fine?
TIA -rp ***NOTE*** Please remove -nospam- from address when replying ***NOTE***
