That's what I thought but I can't find anything with any playhttp://www.ebay.co.uk/itm/Arrow-Exh...3d48260&pid=100005&rk=1&rkt=6&sd=121911074645
another set here if no hawkeye spots them
@tom-e can only be a bearing id say if the wheel has side play in it,if the axle nuts tight it shouldn't move,you can tell by rotating the bearing with your finger,any rough bits or notchyness means they are on their way out

Supposed to be going down to Brighton at the weekend and won't get a chance to strip the rear wheel before then.
