  • geared hubs

    what follows is a response to a question i asked Sturmey Archer (UK geared hub
    makers from time immemorial) about three speed hubs with no freewheel, it may be
    of interest to those thinking of creating a geared uni ;-)
    NB. these are geared >hubs< not deraileurs.

    Dear Sir

    Sturmey Archer did manufacture geared fixed hubs. The "TC" two speed fixed or
    freewheel hub from 1936 to 1942, and the ASC three speed fixed close ratio hub
    from 1947 to 1959. Both of these hubs are difficult to obtain and neither of
    them will drive in reverse as the pawl system will not function in reverse.

    The ASC hubs are currently passing owners for around $300 in the USA.

    I hope this information assists you in your project. Check out the old and
    obsolete specialists listed on our Web site www.sturmey-archer.com one of them
    may have a hub that they are willing to sell.

    Regards,

    T. Wilkinson Customer Service Executive

    Re: geared hubs

    Trevor et al.

    It's possible to convert a S-A three speed hub to a 2-speed fixed gear. See
    http://www.sheldonbrown.com/awfixed.html The BikeSmith in Seattle also sells
    converted multi-speed fixed gear hubs. The problem with these is attaching
    cranks. Making a giraffe is one solution.

    In addition there is a fellow in Germany who is developing what he calls a
    direct drive hub See http://www.ginko.de/user/thomaskretschmer/website.htm

    And last but not least there is a two-speed bottom bracket called the mountain
    drive from Switzerland. see http://www.schlumpf.ch/en_Inhalt.html
