You folks never fail to disappoint! Thanks so much!!
It was at a verywonderful bike cooperative in Corvallis, OR, outfitted with '92-ish Mavic
631 stuff - 53/39 cranks (the "star fish" style, yes), bottom bracket, derailleurs, downtube shifters, and wheels (7 speed
cassette); most of which I sold on eBay to offset the price of the bike. (There's quite a market for some of those parts, turns out.) The
bike had the feel of being original but I wouldn't want to assume anything. It came with a SunTour Superbe headset and Superbe brakes
(single pivot) that "might" be original. The SR handlebars have an '83 date code, as does the SR seat post (27.2mm). It's got a serial number
of K317947 with a larger "7" underneath it. It's set up for recessed nut brakes, two sets of water bottle mounts, fender (but not rack)
mounts. Other than the Bridgestone decals, the frame is marked as CrMo 4130 Bridgestone Quadruple Butted Tubes. Overall it feels similar toan RB-1 or Rivendell Roadeo in terms of geometry and stance.
Did someone buy this bike in '83, and then
update it in '92/'93 with a nice set of Mavic racing parts?
I rebuilt the bike with a mishmash of parts I had on hand - basically making it more suitable for my fitness and the terrain here in the
Portland area. Thanks again for the help!
