    Dust caps.

    If it originally came with one, yes...

    They do a minimal job of keeping dirt out....note the use of the word minimal.

    4000+ wheels built since 1984...


    1. I do not claim to be an expert in bicycle mechanics despite my experience.
    2. I like anyone will comment in other areas.
    3. I do not own the preexisting concepts of DISH and ERD.
    4. I will provide information as I always have to others that I believe will help them protect themselves from unscrupulous mechanics.
    5. My all time favorite book is:

    They're called hub dust caps, and not readily available except for the most expensive hubs. If your hub is fairly common a local shop or bike coop might be able to find a used one in the "junk hubs" bin.

    If it's a freewheel hub, it's less critical since the bearing is recessed fairly deep behind the freewheel. If you don't have one for the right side, you can improvise one with a piece of thin metal or rigid plastic cut out and trapped between the freewheel and hub.
