here's the deal: i have these cranks. sugino gt's. they're five-bolt road cranks for two chainrings. i like them rather a lot.
however, i've now gone a stripped some teeth down on my chainring and would like to get a replacement. the question is: what's the bcd? it's not written anywhere on the cranks, my measurement ability is insufficiently accurate to come up with the right number and sheldon brown doesn't seem to have that info squirrled away anywhere.
