How can I properly adjust my bike gear shifter for optimal performance?
To properly adjust your bike gear shifter for optimal performance, start by ensuring your bike is on a level surface. Shift to the smallest chainring and cog, then adjust the cable tension using the barrel adjuster until the chain moves smoothly. Test the shifting by going through all gears, making further adjustments as needed. Finally, fine-tune the indexing by adjusting the limit screws to prevent chain rub.
