Just got back from my LBS where I tried to get an adapter for an 8inch front rotor on my 2005 Vanilla 130 RLC (hayes disc system). The guy at the shop said I can't put an 8in rotor up front on that fork because it will create too much torque for the dropouts and QR axel. Is this true? I know it used to be a problem on older forks, but man, these dropouts look huge. Whats the deal?
