53/34... say, that's a nice jump, above what I thought was current max of 16 teeth, I was wondering if I could do that on my crank as noted above, I would bet it would need big ring with lift pins. Aftermarket 52 rings seeing now on amazon, good price, no lift pins, flat and no dish to the outside as current 50, my guess is those are for 1X cranks.
