I have recently bought a second hand downhill bike from around 2005 with roxshox boxxer forks and it has the old thru axle with a quick release and wedge type mechanism. Its 20mm in diameter and has a total length of around 200mm if you include the quick release axle. The axle itself is knackered and I could really do with a new one but only realised when it was too late that they're impossible to find. Does anyone have any knowledge about any third party companies making them or do I need a new fork?
