    I have a noisy freehub on my 7-speed Shimano 105 hub.
    Looking to replace like with like, I have been checking eBay
    for such a hub, thinking that I would simply remove the
    freehub from the purchased item and be on my way.

    Thing is, I cannot seem to find such a hub. The ones that I
    found that are advertised as, for example, "Shimano 105 Rear
    HG Hub w Skewer 7 spd FH-1055 Grey ", appear on inspection
    (of the picture) to have uniglide freehub bodies. These are
    distinguished by the thread for the cassette appearing on
    the outside of the freehub rather than on the inside as on
    my current hub.

    Link to eBAY item: tinyurl.com225yd

    WHAT am I missing here? The hubs on eBay are described as
    FH-1055 hubs, which is exactly what is stamped on my rear
    hub. Yet the freehub on mine is threaded for Hyperglide and
    the ones on eBay are uniglide.

    Thanks for any help with explanation. I have already ordered
    the HG hub that is for sale at Harris, the one with the
    solid axle, in order to use the freehub from that one. Still
    I would like my confusion cleared up.

    If it makes any difference, this hub is the original one
    that came with my 1992 (?) red Bridgestone RB-1.

    Thanks, Eric Peterson

    At one point, Shimano made freehub bodies that are
    compatible with both UG and HG. I have one of those. With
    the HG cassette, the lock ring mates with the thread inside
    of the cylinder. The picture seems to show the inside
    thread. To be sure, you can ask the seller about it. GH

    It sort of looks that way to me too. I have 4 rear hubs
    that accept both hyperglide and uniglide. Techincally
    speaking, I suppose they hyperglide with backward
    compatibility to uniglide.
