The Ashima Air Thermal Disc Pads are designed for Shimano Road models M9100, R9170, R8070, R7070, 4770, and RX810. These organic brake pads feature a wave design backing to enhance air contact and include channels for better heat dissipation. They provide a powerful initial bite, low noise, a quick bed-in period, and excellent disc wear, making them ideal for dry conditions. For optimal performance, it’s recommended to replace the rotor when changing the pad compound.
