These are the components on an older Campagnolo-equipped Trek a friend has. I'm trying to identify the groupset and possibly the vintage, but am not having much luck. I can't find a brakeset that looks like this. The closest is the Mirage line, but the only photos i've found of the Mirage line suggest they have a ridge down the face of each side of the caliper. Otherwise, it's pretty close. Any help appreciated! Even better if you can provide a link to some corroborating evidence.
