Hey, I just bought a 20" Dawg Primo frame and when I got it together the front derailluer cable rubs on the right rocker arm. It looks like that over time the cable will saw into the aluminium. I am using the stock XT derailluer. I think I'll end up putting a cable housing over it and call it good I was just wondering if anyone else has had this problem. I should add this is the 2005 frame.
