One indicator to check the adjustability of your SRAM DOT mountain bike brake levers is the model code abbreviation found on your brake lever. The letters "RSC" in your model code indicate adjustability ("R" stands for "Reach Adjust", "S" for SwingLink (which is a nonadjustable feature), and "C" for Contact Point Adjustment).
For more information, please check out our brake manual, visit our SRAM TECH YouTube channel, or reach out to the SRAM Rider Support Team.
