I'll start with this fairly tired example, pics from 10 feet because the paint is pretty bad and the parts group is a mish mash. But it is straight and the rust is just a bit of surface.
Thanks for the link, to be honest I had zero experience with Zeus until this bike came along, and I'm pleasantly surprised at how well this stuff works.
Addendum: found some pedals which actually fit these cranks (14mm) and got out today for a shakedown ride. Very light and racy geometry, but also quite stable. Rides like a top shelf Italian steel bike, which I guess isn't surprising.
