Ofmega/Avocet also marketed an affordable 41T 144mm BCD chainring and their crank arms were machined to provide the proper chain clearance for these rings.
Correct, sir, as always!
What length/offset of ISO BBs are you using successfully on these cranks (double and triple)? I've got my pencil handy to write it down for future reference.
The 102 BCD annoyed me, but the 74 is great!
