The American company Specialized designs and manufactures many cycling components, clothing items and bicycles. One of their hard-tail mountain bikes is the Rockhopper, which has been on the market for over 20 years. The rear derailleur on the Rockhopper operates and is maintained like the derailleur on most other bikes. A rear derailleur is the bike part that changes the gears on your bike's cassette, the group of gears mounted at the axle of your rear wheel. If your Rockhopper's shifting feels sloppy or sluggish, it's time to adjust your rear derailleur.

Instructions

  1. 1

    Mount the bike into your bike work stand so the side of the bike with the rear derailleur is facing out.

  2. 2

    Locate and identify the limit screws on your derailleur. These two screws are near the derailleur cable. The top one is the high-gear limit screw and the bottom one is the low-gear limit screw. These screws may be marked with an "H" and "L," but these marks can wear away over time.

  3. 3

    Pedal the bike by hand and use the left-hand shifter to shift onto your largest front gear. Continue pedalling the bike as you use the right-hand shifter to shift into the hardest rear gear (the smallest cog on your cassette). If the chain won't go onto the smallest cog, proceed to Step 4. If the chain goes over the smallest cog and falls off the cassette, go to Step 5.

  4. 4

    Use the screwdriver to turn the high-gear limit screw to the left a quarter turn. Pedal the bike again and shift back and forth from the smallest cog to the second smallest cog. Continue turning to the left a quarter turn until the chain goes onto the smallest cog smoothly.

  5. 5

    Use the screwdriver to turn the high-gear limit screw to the right a quarter turn. Pedal the bike again and shift back and forth from the smallest cog to the second smallest cog. Continue turning the screw to the right a quarter turn until the chain goes onto the smallest cog smoothly without falling off the cassette.

  6. 6

    Pedal the bike by hand and use the left-hand shifter to shift onto your smallest front gear. Continue pedalling the bike as you use the right-hand shifter to shift into the easiest rear gear (the largest cog on your cassette). If the chain won't climb onto the largest cog, proceed to Step 7. If the derailleur pushes the chain over the largest cog and off the cassette, go to Step 8.

  7. 7

    Use the screwdriver to turn the low-gear limit screw to the left a quarter turn. Pedal the bike again and shift back and forth from the largest cog to the second largest cog. Continue turning to the left a quarter turn until the chain climbs onto the largest cog smoothly.

  8. 8

    Use the screwdriver to turn the low-gear limit screw to the right a quarter turn. Pedal the bike again and shift back and forth from the largest cog to the second largest cog. Continue turning the screw to the right a quarter turn until the chain goes onto the largest cog smoothly without being pushed off the cassette.
