    I swear I have seen it on this very forum, but cannot find the thread, but is it possible to simply remove the disc brake fro ma front mtb wheel and bolt on a cog?...therefore creating a fixed wheel?
    What else would need to be done to it?

    EDIT: Done some more research so some more questions:

    1. Will a bolt on cassette cog fit to any brake disc mount? If not then how can I check these are compatible?

    2. Can the brake disc mount be moved along the hub with spacers to get a better chainline?

    3. What is the standard spacing of a front mtb hub and the rear of an "older" steel bike?....if the modern spacings of the mtb hubs are more than the spacings of the newer bikes then am I knackered?

    4. What bolt on cassette cogs can I use? Or is drilling one going to be cheaper
    Anything I haven't thought about?

    Try Charlie the bike Monger . Website some where. Bolt on cogs are not hard to find. Even on ebay

    They're not cassette cogs or track cogs. They're fixed wheel sprockets pre-drilled with the correct pattern for a 6bolt hub.

    Yes, you put a few washers behind the sprocket to re-position it.

    A front hub is 100mm, I know that older 7speed MTBs used to have 130mm spacing and its possible that a 5speed MTB was only 120/126mm spacing, although i've never owned one. Modern hubs are 135mm.
    If the frame is steel then you can probably spring it in/out to fit either a new MTB hub or a track hub.

    I've forgotten where I purchased mine from, somewhere off ebay. It was about £15, so no its not really much cheaper to drill your own.

    Unless the disc wheel has a braking surface (losts of disc wheels dont) then you wont be able to mount a rear brake.

    Thanks for the help redbike - perhaps I should have mentioned that I plan to put this onto a road frame though? Not a mtb frame teeheee
