Jerry Moos asked:
Anyone know what the BCD was on the Avocet/Omega inner ring? This was the crank where the crank spider arms were drilled for the inner ring fixing bolts, like the Campy NR triple.

Sutherland's 4th says the bolt circle is 74 mm, which means 43.5 mm from hole center to hole center.
