Please check carefully before purchasing. If you are unsure about your brake model, you can pair it as long as the shape and size are the same. For medium to low temperatures (daily riding and light off-road), the braking response is sensitive and quick, offering strong braking power. The material has a balanced softness and hardness that will not damage the disc. Compared to universal semi-metal options, these pads are more heat-resistant and provide greater braking force.
