"Edit: Maybe they're not Gran Compes. Those look longer than 55mm reach to me and have a different straddle cable design. I'm digging them...whatever they are. Haha."
I thought those were Gran Compes as well. They look identical to what came stock on my early Univega Specialissima (before they went cantilever.) They are beautiful, and even with the original pads I still have no problem locking up a wheel in a panic stop. Those have Kool Stop salmons, so I'd say you'd be good to go.
