Ofmega spindle replacement
This Ofmega spindle has seen better days and is pitted on the bearing surfaces. Since Ofmega spindles are not exactly common items I'm looking for a substitute. This is where it gets a little confusing. According to the Sheldon Brown Bottom Bracket Size Database (
https://www.sheldonbrown.com/bbsize.html#ofmega), Ofmega uses a unique size and nothing else works:
Ofmega (Avocet)
Ofmega cranks, including those branded "Avocet" use a non-standard spindle, thinner than either J.I.S. or ISO spindles. As far as I know, nothing else works.
But according to my admittedly rather crude measurements, it has the same taper size as a late model Campagnolo spindle I have laying around which would make it ISO I believe. I'll make some better measurements when I get home tonight but I'm wondering if this might be a Campy clone. That would certainly make it easier to find a replacement. Does anyone have any experience with this?
