To properly adjust the SRAM B screw for optimal performance on your bike, follow these steps:

1. Shift the chain onto the smallest rear cog.
2. Turn the B screw clockwise to increase tension or counterclockwise to decrease tension.

4. Test the shifting by cycling through the gears to ensure smooth and precise shifting.
5. Fine-tune the B screw as needed for optimal performance.
