I originally bought Omniums to work with one of my Panasonics, and I wasn't able to make it happen.
First of all, the spider is super burly and I was not able to completely seat the crank before interference with the chainstay occurred.
Secondly, even with the crank arm seated, my chainline was really out of whack; I was using a formula hub, which advertises a 36mm chainline, which is super tight. My frame supports a 41mm chainline, so even if I got it all said and done I was looking at about a 4-6mm difference, which is way too much for my comfort.
I eventually returned them and got a SG75 bb with a 109mm spindle.
I think these cranks are badass, but probably better suited for newer frames. I think that they should probably work out with your Pista. My advice is to search velospace for dudes running omniums on their pista's, get the rear hub info, and there you have your answer.
