    Greetings...what are the frame differences between a 26" x 1 3/8" camelback and the 27" wheeled versions? particularly in the rear triangle...can one take a taller and/or wider tire than the other, or are they essentially the same?

    Would prefer real world comparisons by someone that has, or had, both!

    Thanks,
    Jason

    I have both and took some physical measurements. I was surprised to discover that there were noticeable differences between the two--the Speedster frame is more generous in its proportions. My rough findings follow...

    Speedster:
    BB shell to rear dropout -- 18 3/4 inches
    BB to seat stay top -- 16 inches
    Chainstay clearance near tire -- 2 inches easily

    Varsity:
    BB shell to rear dropout -- 18 inches
    BB to seat stay top -- 14 inches
    Chainstay clearance near tire -- about 2 inches

    Remember these are rough measurements but enough to illustrate that there are variations, despite the visual similarities.

    Thanks for the measurements @RustySprockets !

    I’m glad you asked about this too @RustyGold , I’m supposed to pick one of these frames up tomorrow, and don’t know what model it would have been originally.

    No problem. I can provide more accurate measurements, if you really need them. But for now, it's sufficient to say that there is little chance of mistaking a lightweight camelback for a middleweight one.

    Is it safe to assume that the frame that can take 27" rims is a middle weight frame and the one that uses 26" rims is a light weigh frame?

    Actually, it was the other way around. The 27-inch wheel was/is a relatively narrow, high-pressure road bike tire commonly found on their "lightweight" ten-speeds.

    The Schwinn 26-inch S-6 tire was a proprietary size (ISO 597) that wasn't exactly chubby, but it did deliver a more cushioned ride. There are only one or two varieties of tire still manufactured in that size today.

    We can debate whether a Schwinn Varsity, at 30+ pounds, qualifies as a lightweight. But, in those days, it was one of their popular offerings.

    What Rusty said :grin:. They are both 'lightweights' as far as what the Schwinn catalogs printed.
