Upgrade your braking performance with this 4-pair set of high-quality bike disc brake pads engineered for SRAM and Avid hydraulic disc brake systems. Designed for riders who demand reliability, durability, and quiet operation, these pads feature a semi-metallic copper-resin compound that delivers balanced braking power for both daily commuting and aggressive mountain biking. The advanced copper fibers enhance heat dissipation and prolong pad life, while the resin blend reduces noise and vibration for smoother engagement. This combination offers excellent modulation, allowing precise control on steep trails, technical descents, and urban environments. Whether you ride an MTB, hybrid, trail bike, or e-bike, these pads help maintain stable braking under varied conditions, including wet weather and high-temperature use. These pads are directly compatible with SRAM Avid systems such as Elixir E1, E3, E5, E7, E9, ER, CR, XO, XX, and DB-series brakes. Designed to match the critical width and height dimensions required for secure fitment, they provide dependable stopping power without unnecessary wear on your rotors.
