    Dahon Bottom bracket

    Hello,

    I ride a Vitesse D7 (wonderful small bike), it is one year old and did a lot of kilometers. I'd like to anticipate a bottom bracket failure.

    Is it a standard BB ?
    Can it use something like Shimano BB-UN53/54 Bottom Bracket square ?
    In this case, what are the dimensions ? (I had this kind of BB on one of my hybrid bikes and it exist in various lengths 107/110/113/118mm and two case width (68 and 73mm)

    Thanks in advance

    Luc

    It is a standard square tape bb, obviously you'll have to get the correct axle width.

    Looking through my spares box it appears my old vitesse D5 HG takes a 68mm shell width bb.
