Love the colour scheme, all goes nicely together in my view. Only thing that lets it down are the STIs, they look out of place on a retro build to me.
I think ergos would look much nicer, particularly the earlier ones. But you'd have to redo drive train if you put ergos on there.
I chose 7800 STIs because they had silver levers which, apart from the cheap variants, were my only real option.
I was thinking of getting some gum coloured Hudz to put on the levers, but would that be too much? Or maybe I could drill the levers... Hmmm...
For what it's worth, I'd be careful about gum coloured Hudz - there's already a few different shades of brown and gold on there, it might look a bit mixed up if they're anything other than an exact match. Celeste could be interesting though...
Also, totally with you on the stamped Campag outers, are you thinking of a Middleburn replacement?
A really, really nice build though. I've got something similarly retro/modem in the works myself at the moment and this bike to me is a great inspiration. Great job!
