    6/7/8 speed chain on a friction shifted 9 speed cassette?

    So the title asks the question directly: can I use a 6/7/8 speed chain on a 9 speed cassette if I am using friction shifting? Related to this question I'd also like to know why chains have recommended gearings. Is it something to do with shifting, spacing, or something else entirely?

    Thanks!

    Width of chain / spacing of cogs
    This is Africa, 1943. War spits out its violence overhead and the sandy graveyard swallows it up. Her name is King Nine, B-25, medium bomber, Twelfth Air Force. On a hot, still morning she took off from Tunisia to bomb the southern tip of Italy. An errant piece of flak tore a hole in a wing tank and, like a wounded bird, this is where she landed, not to return on this day, or any other day.

    A too wide chain can rub against the adjacent cogs and be very intolerant of even the slightest misalignment. You can go the other way and use a narrower chain on a wider spaced cassette.

    If you want it to shift well use a 9s chain.
