WOW!
That was an angry answer, but thank you very much anyways.
that was really helpful.
I think I was just too lost with all the homework I had to do, that I didn't know where to start.

anyhow, before doing the geometry I just googled other track frames average seems to be around 68mm BB drop.
here's one example

compare that to the 58mm on the Gazzetta.
Gazzetta gives you an extra 10mm space for longer cranks.

Very nice.
My 167.5mm Sugino Cranks should work out for this frame then.

Thanks again!!
