Well the crank arrived today. Here's the good and the bad. First the bad. The Ofmega spindle (which actually came with the frame) is trashed. The Bearing surfaces are badly pitted. C'est la vie. Now the good - it's not some weird ultra skinny Ofmega/Avocet proprietary taper. I pulled out my 2002 Veloce crank and spindle to compare. They're the same. Same narrow end, same big end, same taper. So I believe that means it's ISO. That should make it easy to find an appropriate replacement even if that turns out to be a modern Campagnolo cartridge bottom bracket.
