Slipped causing damage to spokes and itself. Went back to the rubber clamp style

This is my second one and it is going on my current build. These are easier to install then the original and once installed you can swap sprockets with just 3 bolts instead of 9. Win, win in my book. These things are awesome. I do recommend keying these to the hub if you can.
