Have a question that no one can seem to answer. Just recently got an 04 Epic Pro and it seems that everytime the rear shock compresses it starts ghost shifting. It wants to down shift into a harder gear at medium to heavy impact. Had it at the LBS and no one seems to know what is causing it. I weight 185 and have the psi in the shock set to 120 and the rebound at 12 clicks. Could this be cause by too much / not enough air pressure or too fast / too slow of rebound. I'm getting the recommend sag of 10 mm and rebound seems to be good but I'm still new to this F/S thing. This is my first F/S and it would be the prefect bike if I can get this small problem solved. If anyone as any answers please help, it's killing me on rough up hill rides.
