    Hi,

    Apologies if this is a frequently asked question...

    I'm upgrading the wheels on my old bike. The current rear wheel is a clunky
    old lump of steel with a poor quality five-speed screw-on freewheel. The new
    rear wheel has a 105 cassette freehub, which I understand takes an 8 or
    9-speed HG70 cassette.

    What type of chain do I need with this? I know what the HG signifies, but
    beyond that the arcane letters and numbers that go with chain specifications
    might as well be runes as far as I'm concerned. Any advice much appreciated.

    And will I need to replace my chainrings too?

    (other matters: I have checked the dropout spacing and it's 130mm, so no
    problems there. As for shifting, I have friction levers, so that is not an
    issue either. Rear mech should be fine with the new set-up too.)

    thanks,

    d.

    Any modern chain for 8 or 9 speeds (depending, of course, on which
    cassette you get). Do yourself a huge favor and either get a chain
    with a quick-link (Sram and Wipperman chains come to mind) or buy a
    quick-link separately. Modern chains can't be broken and re-joined
    with the pins they have; you join them with special pins, or just
    use quick-links (which make it easy to remove for cleaning).

    Not likely. Try it first, you'll know if you need to.

    Aha. Thanks for the tip. And your other comments.
