Owing to the fact that I've spent too much time gaming this year and have gotten fat, I've just broken one of the wheels on my nitro e220 chair. Does anyone know where I can get hold of a replacement wheel? I've searched about, including ebay and cant seem to find anyone doing them. Seems a bit of a pain , especially just before xmas, to have to buy a whole new chair when the only thing wrong with this one is 1 wheel.
