topstone has a poorly designed rear thru axle dropout, seen countless problems with them
didn't know about this. a mate is looking to buy one, what's the issue?

The frame insert is a one screw affair with means it's not terribly secure anyway but coupled with the through axle it struggles to engage threads reliably and ends up cross threading or being impossible to line up etc and I've seen at least 3 mullered ones where both axle and dropout are screwed. It also doesn't really do its job of breaking on a crash very well and instead the mech tends to die- granted it's not unique in that. You can buy aftermarket CNC hangers that fit better but the last one I tried had too much ano on the threads so it had to be tapped straight away to be useable.
