SR 21 COMPOUND
Technical Description
The SR21 is a high-friction sintered metallic race brake pad engineered for maximum braking torque and extreme performance applications. It shares the same endurance-focused sintered construction as SR11 but delivers a significantly higher friction level and more aggressive initial bite. The compound maintains stable performance across a wide thermal range, making it suitable for high-load race environments where maximum stopping power and fade resistance are critical. Like SR11, it uses transfer-film technology to minimize rotor wear while sustaining consistent braking under extreme conditions.
