    Almost. S.G.D.G. is the acronym for "sans garantie du gouvernement" or "without government guarantee." In other words, the French Government granted the patent protection but is not responsible for...

    I prefer both front and rear, but its a fixed gear, so if you insist on only one caliper put it on the front since you can use your legs to brake the rear wheel.

    +1 this. Unless the bottom bracket needs to be completely replaced, don't bother removing the fixed cup. Clean it in place and pack with fresh balls and grease.

    This is the band and left shift lever to fit over this boss, but it's still missing the right shift lever hardware (could be salvaged from a standard set, though):

    I doubt that very much. That steel loses rigidity over time is a persistent myth, but a myth nonetheless. Far more likely is that frame fashion preferences moved on from steel tubes in classic...

    No, there are actually cable guides welded to the seat tube for that routing. I just worked on one of those last week and ended up bypassing the installed guides to get a decent cable routing that...

    Yeah, I guess it's a problem, albeit somewhat remote. Low spoke count wheels are probably more likely to jam, as a squirrel won't even begin to fit between the spokes of a 36 spoke wheel.

    Before they allowed derailleurs and support teams in the Tour de France, it was typical to use a fixed/fixed hub with two different size cogs and flip the wheel around when you needed the other gear....

    The Trek bonded aluminum frames used epoxy. Our recommendation for refinishing at the time was bead blasting the old finish to remove it. The original finish was Imron; not sure if that's even...

    I've never seen the "copper" color, and I agree the gold has a propensity to fade. My black ring is holding up well, though.

    The BB shell has the "new" Cinelli logo, so no older than around 1980.

    I see this a lot with department store bike assembly. Not only does it degrade the handling and increase shoe/wheel overlap, but often the cables are wound around the head tube so that neither the...

    To be sure, but even if the CR-18 extrusion was designed to be machined, the non-machined versions of the rim will still have thicker sidewalls than the machined versions, and thus could be expected...

    Is the CXP-33 available in a non-machined version as well? I suspect the CXP-33 extrusion was designed with extra thick sidewalls with the expectation that they would be machined.

    While I'm not fond of the look, unicrown forks are not only less expensive to build, they are also stronger and lighter than traditional forks.

    That may be the case with rims explicitly designed for machined sidewalls, but as far as I can tell, all CR-18 rims use the same extrusion (that's why they get the same model designation), so the...

    Yes, it's standard English thread. BSC = "British Standard Cycle." Bottom bracket shell widths can vary widely, and should never be taken as an indication of thread type.

    +1 this. IIRC, they used 1" seat tubes. A front derailleur from a Schwinn Varsity or Continental should work, as would an appropriate shim under the clamp.

    That's a pretty early one, with the super-short Tange lugs and custom-milled Ishiwata SCM for crown.

    I still use my first Duopar derailleur from 1978, when they first came out, on my commuter bike and its never given me problems.
