I have a 2003 XT M752 Hollowtech crankset (4 bolt). I just tried to replace my 32T middle ring (part of complete drivetrain replacement).
I ordered an XT 32T 4-Bolt ring, and it doesn't fit. The cutouts for the spider are too close to the BB (spider was just a bit bigger on the 752 than the 760). Turns out this is for the M760 Hollowtech II
a) Where can I find a 4-Bolt XT M752 chainring?
b) I know some of you are going to say "Go Ti" (not a bad idea b/c I'm 200 lbs and spend 95% of time in middle ring) but I'm not sure I'm really understand pros/cons of ti rings or ramps & pins. My main goal is the best shifting performance, not spending $40 to replace a ring once/year... Doesn't it make more sense to wear out the rings than the chain? If you wear the chain, you trash the cassette too don't you?
c) What other easily accessible brands are comparable in terms of shfting quality?
