I'm a newbie to a bike with gears. Been riding a single speed. I now have a Giant Sedona (Comfort Mtn) which has Grip Shift Twist Shifters. Thougt I understood that when I have the left in 2, I shold be able to shift to 4-6 on the right grip However, it is smooth only on 4 -- when I shift up to 5 it grinds a little, when I go to 6, it grinds still more. Does this need an adjustment. Thanks.
Forgive me for not knowing the correct lingo yet. :confused:
