700c wheels - will they squeeze in an mtb frame?

I have a pair of 700c rims laced to Deore disk hubs - is it possible that they will fit a regular MTB frame that would normally take 26" wheels? I'd be using disk brakes not Vs so that wouldn't be an issue. I haven't bought the frame yet but just wanted to have an idea generally before I start bidding on e-bay! Any help would be much appreciated.

    I don't know if this will help too much, as i don't know what frame you're bidding on. But Mavic make a wheel called Speed City which has 700C rims, takes 700X25's and is used for turning MTB's into commuters and road training bkes.
    So possibly, yes.
    It's nice to be important, but it's more important to be nice.

    A mountain bike wheel with a 2.1 tyre and a 700C wheel with a 23mm tyre have the same overall diameter to within a few millimetres, so in general, this will work.

    However, though it's a bit tight with some forks and frames as it depends on exactly how much clearance the builder has designed in for the tyres. Those few millimetres turn out to be crucial. If a frame's intended to take the fattest MTB tyres possible you'll be fine, but a cross-country frame and fork with very tight clearances might only be able to take 700C wheels with the skinniest tyres.

    Yes it'll work fine. I've done it successfully to lighten up my wife's bike and make it suitable for her to do duathlons. It's only a 14" frame which is why the wheels look so huge http://www.pinkbike.com/photo/1292414/

    The tyres are 700x25 road tyres but she now has 700x38 cyclo-cross tyres on so she can ride tracks and trails as well and no clearance problems.

    Thanks to you all for your advice, I thought it would be possible but not with all mtb frames/forks - i guess that's the risk I'll have to take......

    I suppose your Deore hubs are 135 OLN?

    What risk are you refering to. It works. Here's the wheels fitted to my hardtail with the cyclo-cross tyres on http://www.flickr.com/photo_zoom.gne?id ... 914&size=o
