Disc rotor fouling brake post mount....

Hello folks

Building up a new frame (Orange Crush - parts swap from a P7). On fitting the rear wheel (Deore hub), I found that the brake disc (Shimano XT) fouls the post mount - not a lot but even not a lot isn't right!

This seems to mean that I need a deeper retaining nut for the cones on the non drive side (and vice versa) or an extra washer and a tighter fit for the wheel in the dropouts. This seems a bit odd though - I'd assume that the placement of the post mounts would always allow clearance for the discs as these are surely fixed standards. Is this just something that occasionally happens (and if so, how is it normally dealt with?) or is it a frame problem. I can't see that it is a problem with the wheel. The P7 used an adaptor on the rear and it worked perfectly well.

Advice appreciated!
