I have I have SRAM Attack Grip Shifters on my bike (with Shimano Deore XT rear and front shifters) and the actual hand shifting mechanism feels very tight. I have checked the shifter cable and it is tensioned properly so I know it is set up okay. It does shift throughout all the gears in the whole range of motion but it gets very tight feeling as I move through the gears..1 through 9 work okay in that order but if I try to go back from 9 through 1 the other way, it is super stiff feeling and is not natural feeling, I need to force it into each next gear.
Anyone have any ideas about what could be causing this or how I can fix it?
Thanks.
