To adjust Shimano gears for optimal performance, start by ensuring the bike is on a level surface. Shift to the smallest chainring and cog. Use the barrel adjuster to fine-tune the cable tension until the chain moves smoothly. Next, shift to the largest chainring and cog, adjusting the high limit screw to align the derailleur with the chain. Finally, shift through all gears to check for smooth transitions and make any necessary adjustments.
