So here's the idea I had most recently.
Keep the Campy bb
Forget about the 52 ring
Put the Red Clover 42 on the outer position
Use the triplizer holes to put a 32 ring on the inner position
Run an Nx11-27 cassette, not freewheel, at the rear
This gives a gear range of 32-103 inches, where the original setup (52-42, 14-28) gave 40-100 inches
Would the triplizer bolts interfere with the crank arm? Hm...
