I can no longer recommend American Classic with 8" rotors. The rotor tabs tore off 2 hubs. They use the same design and amount of material as their 142 and 135 hubs that I've used with 6&7" rotors without problem but 8" with DH loads tears the hub shell apart.Well put! I've found engagement to matter more on the bmx track than in DH. BTW, I'm reviving this thread because a couple hubs have been mentioned that have now had time to be tested. And things change. So...any revised opinions?
