    Mount back wheel in the front

    Hi everyone,

    Quick questions for the experts.

    Can I mount a back wheel of a mountain bike (cheap supermarket one) on the front after removing the cassette?

    I'm trying to make one working bike out of two trashed ones.

    Thanks,
    - D

    In addition to a problem mounting it, the rear wheel is "dished" to one side to make room for the cassette. It won't wind up in the middle of the fork legs and will probably hit one side.
    To avoid injury, do not ride with your eyes closed

    The trouble with common sense is it is no longer common

    That isn't the reason it wont work.
    A properly dished wheel will have the rim centered between the jam-nuts (or what ever you have, cartridge bearings etc)) - If it were able to fit, theoretically, the rim would be centered just fine.

    The problem, is that the hub drop-out width is wider for the rear by about 35mm (typical:135mm rear; 100mm front)

    Also (typically) a rear hub has a 10mm axle and a fork's dropouts usually fit a 9mm axle.
    Honestly... ahh I give up

    sure you can, you just have to swap out your front fork to this

    Assuming it is a freewheel (not cassette) style rear wheel, you would remove the freewheel, and play around with the axle spacers and axle width.
