BITD I ALSO HAD ACORNS and ogk,s,areo zytecs and earlier on simplex's,had some motomags on a 6 ton puch murray,and i also had some white z rims with z hubs,thing was though i got shut of them all as they came on bikes i broke or bought to sell as i was riding them for my favourite skyway t2's.
iirc i had ogk; and the hub slipped sideways,i never seen that mentioned but they honest moved around on the spindle. that was one reason i'd say they way pony lol.
