I have a rear wheel with a 12mm thru axle. Last night I was riding xc and the freehub blew out. The pawls will not engage at all. I've called azonic. I also haven't had time to take the hub apart yet. I would like to know if anyone has any pointers on rebuilding or maintenance. I use it on my DH bike, I just don't have my HT back form Rotec yet. I do some urban on it, but nothing real big. I mostly ride dh stuff at Mansell trails here in Atlanta. I've only had the wheel since last October.
