    Hose clamps work. Do I see pieces of old inner tube under the clamps? That’s what I used. The Surly Karate Monkey utilizes that bent seat tube trick also.
    (Thirty-plus years later) This bike looks like a sprinter indeed.

    Call me Crazy, but I see a candidate for an Over The Top Old Ten Speed Conversion.

    And why am I suddenly hungry for pie?

    thanks for the kind words. You do see the inner tubes under the clamps to protect paint. I hid them the best I could but don’t mind them poking out a bit so people can see them if they look hard enough. I was concerned when I acquired the bike where to put the water bottle cage; thankfully it worked on the seat tube. I wanted to avoid the screening on the downtube.

    I don’t plan any conversions of it anytime soon, I like it the way it came from Chicago, although I am wishing it had more gears to go faster. Alas, it’s a great bike to ride.

    Pretty cool, in great condition, and not common at all, Daniel! The chrome fork looks like it just belongs there!
    Found it at http://www.trfindley.com/flschwinn_1971_1980/1974_15.html and http://www.trfindley.com/flschwinn_1971_1980/1975_09.html
    Ah, yes, those were the good old days: when, to Schwinn, anyway, ‘lightweight’ meant 36# (with chromed-steel rims and a one-piece ashtabula crank)!
    “Sprint” is aptly-named, since it probably only does that well. I’m going to guess its short production life was due to the typically-relaxed seat tube angle, making it a wheelie-machine when climbing hills (in the saddle).
    Depending on Daniel’s geometry (while considering “knee-over-pedal” guideline), a couple of things could be done to minimize the effect: first of all, try sliding the seat forward, and then, if still not enough, rotate the seat rail clamp hardware 180 degrees (especially if a longish stem may have the bars too far forward for a shorter rider).
    The so-called ‘short-coupled’ geometry even briefly showed up on Schwinn’s expensive 1975 Touring Paramount, too: http://www.trfindley.com/flschwinn_1971_1980/1975_06.html
    While super-short chainstays improves rear triangle rigidity for high-performance track and road racing, short chainstays on a bike meant for loaded touring could be considered too rigid for stability, long-range comfort, and potentially have a larger-footed rider’s heels strike rear panniers. When compared to race bikes, a classic touring bike would also have a longer, more stable/comfortable wheelbase due to increased fork rake and relaxed head tube angle).

    I need to edit my post: Electro forged frames were not fillet brazed, the higher end Sports Tourers and Super Sports were.
