So a co-worker of mine is selling me a steel Bontrager frame of unknown vintage. Does anyone know anything about Bontrager frames that they can share? I can't find much useful on what he made and when he made them on the web, and I don't know what this bad boy is. It's OX steel tubing, about 18", has wishbone style seatstay, and has a nifty little bolt-on anti chain suck device integrated into the chainstay. From what I've seen online, the Privateer didn't have a wishbone chainstay, so I'm stumped as to the model and year.
