Yeah, was aware of that. Came out after I bought mine. :-(watch out for pumptracks
(check that mtbr link I posted if you didn't)
I've only had one fox fullface. One concussion on a pretty moderate fall and the thing literally coming unglued everywhere is all I needed to know about fox
I ride pumptrack with a pisspot or a XC lid, so no chance I can break the chin bar.
The Fox Flux XC lid is solid for years now. In contrast to the A1, the pads and silicon grippers did not come unglued. While the TLD was the higher quality helmet by initial feel, the Fox withstood the test of time better.
I assume a Fox DH helmet gave you the concussion? Did it crack during the crash? A friend had a concussion in his Fox MX helmet and it seemed to not have absorbed the impact. Maybe the design for different speeds theory holds water?
