Ensure all cable housings are correctly positioned and snapped into the frame's cable stops. Tighten the gear adjustment screws and then loosen them back by 3 turns. Shift the shifter to the middle gear. Then adjust the gear adjustment screws on the rear derailleur. First adjust the smallest cog. Release the shifter to the smallest gear. Check if the smallest cog and the guide pulley are on the same plane. Then adjust the large cog side. First loosen the L-side screw, then after the chain is engaged, tighten it until both cogs are on the same plane.
