Hey, Chattymatty.... I could never forget about the KingSting, although that thing rides the fence between mtb and BMX cruiser even more than the Sidewinder does. Both the King Sting and the Sidewinder, though, were severely lacking in the brakes dept, and were geared pretty high... I wonder if the Sidewinder would've done better just by having cantilevers.....Actually, with as many as there are still out there, I guess they sold fine.... but the guys who'd just bought a Spesh or any of the Japanese bikes probably showed up all the Schwinn guys on the trail, so there weren't as many repeat-buyers of early Schwinn mtbs as they would've liked.
Excellent point re: the California Cruiser/ Klunker 5.... Of course, by then, California Cruiser was an incorporated business or whatever, and Schwinn should've known better... but the "Klunker 5" debacle seems unfair, looking back at how the majority of the original klunkers were repurposed Chi-town Schwinns.
In other news, I put a 2.125" Kenda k80 mounted to a 7x knockoff into the rear of my collegiate. It was a bit tight, but it fit.... slightly more room than the same set-up had in my '79 Varsity frame. (I rode some light trails with the k80 in the Varsity.... no rubbing, but had there been even the tiniest hop in the rear rim, it would've....) The Collegiates seem to have the same basic front triangle as the 27"-wheel lightweights, but the rear triangle is slacker and longer, so I guess there's more wiggle-room if you run the rear wheel pretty far back in the drop-outs. NBD, though.... that particular Collegiate has a different fate than the faux-Sidewinder build. I'll PM you re: the frame you have, soonish.
Aray51, sorry for the thread hijacking; again, your Thrasher rules, nice score, I'm serious even if this probably reads as me just trying to do some CMA-work!
