This is why buying/riding the right bike for the right trail is important.
Some kid thought he'd be cool by putting a long travel, dual-crown fork on a Trek 4300 which is designed for XC. If youre gonna DH, then get a DH bike. If you dont have a DH bike but you want to ride DH, please dont put a DH fork on your XC frame and expect it to last.
The funniest part is the quote from his thread...
