So, I am about to go for one, and put a down payment on it, but you guessed it, I have a few questions.

Any problems? Do you think the frame is somewhat resistant to rock hits? I haven't bashed my alu RX against rocks yet when going over technical descents, (came close) but who knows.

I don't care about having the frame scratched, but I certainly don't want it to fail catastrophically after a few dings......

BTW, I ride a alu RX right now.....
