First of all, thanks for the fast reply.
I took a couple of pictures just now for clarification.
I don't really know how it happened, I do know that I tend to hit my hub guard on my way into a grind so that's why I thought it was due to the plastic guard not being supported all the way.
1st piece that broke off
2nd piece
Does the new (or older, in this case) tooling prevent this from happening?
I really wouldn't mind getting a different hub guard, I understand that sometimes a part isn't made for everyone.
The hub itself is great though, I love that thing.
Thanks
