I take triples apart, the first ring is not ramped @ least what I've seen.
The mid ring is ramped\pinned, the outer is ramped.
I THINK the important effect will be ramps on the big, not the small.
yeah, I figured the small ring wouldn't be that special, my only real concern was the alignment of the teeth on the small ring to the pins on the big having an acceptable or unaccetable effect.

I've also seem em in 144, 135 and 110 BCD.
The cranks maybe SR? I eyeballed them against an old shimano 600 drive side crank and they looked to be the same. it's entirely possible that I'm wrong, of course.
thanks for the advice, you two.
