Original equipment pads for no-compromise disc brake performance. These pads are compatible with the new 2018+ SRAM Code Brakes and SRAM Guide RE Brake Calipers. We highly recommend using Metallic pads in all SRAM Code Brakes for the best possible performance! Only use Organic pads if you&';d like to make your brakes more quiet, but do expect slightly less powerful braking power.
