funny new post to post 180disc ones, two bolts instead of four, probly to save a couple of grams, that's pretty poo...
They've been around for 3 years or more. Much neater mounts imo.
Sorry tho mosey, no help there I know. Sucky situation, most of us have popped threads or filed a bit too much off something etc along the way.
I'd be scared the bigger disc would exert more pressure and snap the forks lol.less force from a 180mm rotor, so it's ok. If you need a new mount and bolts just PM me, I have a box full and don't use PM forks these days, got spares I can send you foc.
