I have a 24 speed bike that I ride in the middle ring almost all of the time. When I get to the second highest (second smallest) gear in my rear cluster the rear derailleur hits the chain slightly and when I go to the highest (smallest) gear it rubs a lot. Is this something to be concerned about and if so how do I fix this. The bike seems to shift gears just fine.
