Shift your front derailleur into the middle or smallest ring, then wind your rear barrel adjuster in fully clockwise, then out one turn. Release the cable mounting bolt on the back of the derailleur. Step 2. Pedal gently, and push the derailleur until the chain moves up to the second-smallest cog, then stop pedaling.hift the front gears to the smallest ring, and the back gears to the largest cog. Fully wind in the low adjust screw. You should complete this procedure with a slack gear cable, so you can be sure that cable tension isnât overriding your low limit setting.
With the initial indexing done, you can now set the high and low gear limits. First, shift onto the smallest sprocket and then use a small screwdriver to tighten the H screw at the back of the derailleur. If you do this slowly you should feel the point where the screw touches the derailleur body.ith the derailleur in its relaxed position, the cable can be connected. Typically, the shifter will be set to the highest (small) gear and so the cable is under virtually no tension. (Low-normal, or rapid-rise, mechs will be relaxed in the lowest (large) gear, so the shifter should reflect this).
