This is one of the earliest mountain bikes I've ever seen or owned. No brake mounts, so probably meant for sidepull calipers, or hub brakes possibly? Has a VDC sticker on it, and a CW head tube decal. Serial number is MT09, so low production and possibly a test or prototype frame? I know I have never seen anything like this, ever! The rear dropouts are plate style, but with Campagnolo forged dropouts welded onto them. I am still puzzled by the reverse sloping top tube, though. The slant is enough that if it had a level top tube originally, the fork would have to have had a separate mount, or else a VERY deep crown. I am really going to enjoy this one, and keep it around a while. The plan is for first gen Deore friction thumb shifters, and a set of Suntour Mountech derailleurs. The brakes, well it's going to be rough either way. I either will get some MX brakes, or some adaptor plates and run some of the reproduction Dia Compe U brakes. Getting some wheels built with hub brakes isn't in the budget right now.
