So I have a trek 1000SL that I'm trying to get tuned up for ride the rockies this year. It has Sora triple shifters and everything else tiagra (9speed), and the rear derailleur won't shift up or down. When I use the shifter, it still gives and takes tension from the cable, which makes me think it must be a derailleur issue and not a shifter issue. Would getting new cables/housing fix this or do I need a new RD or a whole new gruppo?
