Just bought a used M6 with a brand new revox rear shock. The back tire was hitting the seat tube so Intense sent me new dropouts and told me to put a smaller tire on it. . The new dropouts say M6 135mm on them and I set the shock up for 30% sag. I can sink down on my flat driveway and still get it to rub. Is there a thread on here or can someone please tell me what the hell is going on?? After researching it seems to be a very common problem but I haven't been able to find a good explanation of how to fix it. This is probably old to most of you but It's new to me. Any help would be appreciated.
