Rob is a big time piece of shit! We bought 3 4mill cranks from him last year. My buddy snapped his in half after about 10 hrs on it. So we sent it back to Rob to fix since he has never seen that happen with his cranks! He gets the crank and tries to tell us it's not his and we reassured him it was! Oh ya that's mine he said "but those cranks are no good and I wouldn't run them"! That was his exact words and would rebuild them for $380!! I don't know about you guys but if a builder admits he screwed up and sold you a $500 PC of crap crank and says he will make it right by charging another $380 to fix. In my book that's a big time scam!! So in short don't by anything from RDZ!!! My 2 cents.
