This was my first ebay buy--I wasn't patient enough to find the right size bike locally. It still shocks me that a world class 35 year old bike costs less than a crappy new department store bike. A lot less if you're willing to cobble it together with used parts yourself.
Made in Wisoconsin, the 600 has basically the same "sport" geometry as the 500, although I think the chainstays are just a little longer. It's made with Reynolds 531 steel instead of 501-- technically an upgrade, but I can't really feel much of a difference. In '83, the downtube shifters were clamped on instead of brazed like they were in '85, so the downtube shouldn't have any weak spots.
I built it up to be fixed gear, of course, using a lot of parts from my old Trek. I added fenders and picked up some cheap bullhorns and cork tape at Mr Michael Recycles Bicycles, a true St. Paul treasure. I'm in there all the time scrounging parts.
I think this will be my new daily ride. My other new whip, well...for some reason it seems to be just a little too special and possibly temperamental. More on that later.
When this bike was made, I was tooling around on my first ten speed, a Huffy Sante Fe, which is hardly collectible. These vintage Treks are quite collectible, tho. Many now live in storage or on display and aren't used much. I plan to put plenty of miles on this Trek in all kinds of weather. After all, bikes were made to be ridden.
