I guess the other calipers were 39-49mm drop, or "short-reach" stíles, and these exage calipers are longer reach ones. 
Anyway, the exage calipers are really awesome, light as hell, and with decent pads they can bite!
Very nice frame and good job with the bartape as well.
Just, slam the stem lower!
Always nice to see UG blocks on the rear wheel, though I'd check your rear hub wheter you can change the freilaufkörper to a new HG compatible one.
Though these UG cassettes are made to last for ages.

the levers (brakes) very nice, they remind me of some modolo-model.
