Dude lay off him, he's only lookig for help and all you can do is have a dig at him. I suppose you could get one of them 74 Kings tensioners, but i'm not sure how good they are, as i've heard different reviews on them. I had this same problem myself and everytime i missed a sidehop or something my hanger bracket would go, so i got a modsock. Of course it would be a cheaper option to get a tensioner but you rally ca hit the hell out of the modstock frames andif your wheel moves (not that it does) you can move it back and into tension easily. I know for a fact by how my riding is that i would have broken several of those tensioners by now. If you did get a modstock then you wouldn't necassarily have to get a King BMX hub, but they are ridiculously cheap from AspireVeloTech. You could even get a Profile BMX hub which i think retail at around £160. Or another option would be to get a mod spaced fixed hub and use a front freewheel like a Tensile or an ENO.
