well on my bike theres 3 big gears, and 7 smaller ones on the back wheel. On the 7 back gears, when i switch to the 6th its already on the 7th (the smallest one); when i switch to 7 it stays the same, and when i switch back to 6 it still stays the same! any suggestions (besides taking it to a shop for a tune-up)?
