Chainline is 45mm? Fuck I've just bought the same frame and assumed chainline would be 42mm standard. I just hope the omnium tracks have enough thread for spacers.
Omnium (and all GXP chainsets) can only be spaced via the non-drive side as that is where the spindle is held captive - thereby reducing your chainline (except in case of inverse shim).
