I assume that it was taken off an ex pro's bike, but have no idea who, where or when.Andrehttps://www.blogger.com/profile/10710286946127653189noreply@blogger.comtag:blogger.com,1999:blog-5896237156501813410.post-76995529341914580402011-05-11T02:26:42.088+10:002011-05-11T02:26:42.088+10:00hi all, i'm the seller. these brakes were on a...hi all, i'm the seller. these brakes were on a very tired colnago master that i bought. after taking everything apart and cleaning the whole record gruppo, i noticed the "prototype" brakes and then did some poking around and came to the conclusion that these are pretty special. i have no idea how they came to be on this frame. anyway, thanks for the publicity.corey sar foxhttp://www.foxgalleria.com/bicinoreply@blogger.comtag:blogger.com,1999:blog-5896237156501813410.post-26186006691998938152011-05-10T20:27:13.965+10:002011-05-10T20:27:13.965+10:00Hi Daus, certainly a valid point.

The fixing bolts for the brake blocks and the recessed caliper arms in which they sit are very reminiscent of the delta calipers. They are not seen on production models. Also the rocker (component BR-RE017 in the 1994 spare parts catalogue) is made of a bent steel plate in the production dual calipers that I have seen. This example has what appears to be a machined component (yes it appears exactly like the image in catalogue but the real item - at least from 1994 onwards - was a much cheaper looking steel plate). If they are counterfeit, then the seller appears to have done a pretty good job of it.wingnuthttps://www.blogger.com/profile/11016671831457597440noreply@blogger.comtag:blogger.com,1999:blog-5896237156501813410.post-77492201880096303852011-05-10T11:34:54.903+10:002011-05-10T11:34:54.903+10:00Although interesting, this item screams counterfei...Although interesting, this item screams counterfeit. Laser etching is easy to do on anything today versus 2 decades ago. Why would Campagnolo have taken the time to laser etch something......then?Daushttps://www.blogger.com/profile/08470166670899223380noreply@blogger.com
