For Sale: Shimano Dura Ace road Crank Arms

Nice, I have them as well.

If you want a perfect 42mm chainline on the outer ring, with 1/8" chainrings with these cranks, pair them with a Miche Primato track bb, 107mm. I would then machine off the inner ring tabs.

The Miche is ITA, the DA cranks are JIS, and therefore the cranks slide deeper onto the BB giving the perfect chainline. The trick is that the DA cranks are deep enough the BB does not bottom out, a perfect match actually.

This is actually really interesting and helpful info, I have just bought a pair like these and wasn't sure what to pair them up with...

Thanks for sharing!
Nice cranks and a good price too...
