Hi all
I've searched this forum but couldnt find my specific question though I'm sure it's been asked before.
I bought a bottom bracket bash guard. It has a bracket that goes over your boom bracket thaking the place of a spacer. I'll include pics. My question is if I actually bashed into a rock or curb at speed would it hurt the bb? More importantly the threads in a aluminum bb shell? Bb are cheap, usually cheaper then a chainring. But destroying a bottom bracket shell wouldnt be. Has any one had any experience with this? Thanks!

This goes over the bottom bracket
