The Trek version appears to be a clone, albeit with the Trek logo stamped/molded in (see post #53 of the linked thread). My '94-is 950 has one, with Shimano cantis. I remember finding a document on it similar to the Suntour doc, touting it as the latest space-age advance in cantilever brake technology, or some such.

It was fun revisiting that thread, seeing some of the more creative designs. Someone should come up with one depicting Yosemite Sam saying "BACK OFF!", with the straddles going to the canti arms coming out of the guns in his two hands.
