dynamos on big forks

Discussion in 'Technical Chat' started by Julian Bradfield, Nov 5, 2010.

  1. After the recent thread about the IQ Cyo, I was contemplating it -
    but I don't want to fit a hub dynamo.
    However, I wondered: how does one fit a tyre dynamo to a bike with
    carbon cross forks, which are much wider than traditional forks?

    My sidewall 'mos always went on the back.

    It's just a question of appropriate mounting. For carbon forks you'll be
    wanting to be very careful anyway, as the conventional bolt up clamps
    could result in a messy and painful failure.

    Hub dynamo is the best option, but if you _really_ don't want to,
    something bolted to the seat stay is likely to be a good option, and
    more likely to be achievable with easily available kit.

    There was the Zinken Dynashoe bracket for mounting a dynamo on the
    canti brake stud, which I have on an old MTB and works well. But seems
    discontinued now. Might find one somewhere online.

    Or SJSC do a different type of bracket.


    Or similar looking one from Basta:


    Or mount on the seat stay.

    FWIW, the Cyo will happily run on DC of the appropriate voltage and
    polarity (specs in the manual) if you want to be arsebackwards and build
    a battery pack for it.

    I have done exactly this and it works marvellously.

    You could try a bottom bracket dynamo, I guess.

    I've got an unused Zinken Dynoshoe still bagged up which I could sell
