Picked up some super cheap wheels and freehub appears to be mangled! Binds when fully seated so assume it’s all those broken teeth.
Superstar sell a new freehub but for £50….but I thought I’d check the communal spares boxes first as that’s a bit pricey.

Anyone got a cheap spare?
Thanks Chris

The problem is a design one the hub axle is too flexy and you get the damage shown in the second picture

Sorry that doesn't help
