Hi might be one for @danson67 Or anyone else in the know.

Looking for advice on converting a pair of wheelchair wheels from half inch 12.7 diameter axle to 12mm which the current wheels are. Are there any bearings to do the job or is it a case of getting 12.7 axles and filing down?

new wheels current bearings are in R8 2RS.

existing wheels are running 600 1RS.
does not seem to be as easy as getting some 12x28.58x7.94 bearings as nothing seems to exist.

any help greatly appreciated.

Thanks Chris
