    Cables and Casing

    Is there a correct size derailleur casing for early friction shift bikes? Modern cables and casings work great. But they are so skinny they look out of place. 2mm cables and 6mm casing for brakes are still available from moped suppliers new. So is there or was there a standard derailleur cable/casing size?

    If by modern, you mean the ubiquitous 4 mm stuff with plastic ferrules? Then sure, the 5 mm was standard for derailleurs for many years before the switch.

    Brakes, back in early canti days, Shimano at least, used some 6 mm stuff, but I don't recall derailleur being bigger than 5, and older than that, it was just the bare metal "phone cord" spiral stuff. Suntour used 4mm as OEM, in the 80's, for example....

    So back in the door brake and gear casing was the same.
    We still use the same standard in brake cables today.
    Just use brake outer cables and with modern gear cable inner (same as the old gear inner but better made) and your away.
    There are a few old Cycle Shops with old stock in New Zealand.

    5mm always seems like a sloppy fit in the brake lever adjusters on Eighties bikes.

    You can find some old shifter & brake housing from time to time online. The oldest stuff I could find measured 5.5mm OD, thickest shifting cable I could find was 1.4 compared to the normal 1.2mm.

    Brake housing I found was 6mm and 2mm cables I bought from bmxguru.

    The original stuff on my Ritchey was close to the same size, but super old with custom ends.

    Honestly using smaller housing isn't a big deal, if it wallows around to much you can always try and find a cable end to fit over the other cable end & upsize the ends. Or just hunt around for the right stuff, took me a while. But the bike turned out well.

    Just finished this yesterday, (Installed crank, levers, brakes & grips)
