What customers say
The SRAM HS2 Disc Brake Rotor is highly praised for delivering superior braking performance and reliability. A dominant theme is the remarkable improvement in stopping power and modulation, boosting rider confidence on challenging terrain. Users frequently commend the rotor's exceptional heat management, which effectively prevents brake fade during aggressive riding. Once properly bedded in, the operation is notably quieter with reduced vibration. While slightly heavier than some alternatives, this trade-off is widely accepted due to the substantial performance gains. The consensus is that this durable component significantly elevates the entire braking system, making the investment worthwhile for enhanced control and safety.
Know before you buy
The HS2 is specifically engineered for better thermal management and increased stopping power. Its design features a unique brake track and heat-dissipating paint on the spokes, which helps keep temperatures lower during long, aggressive descents.
This model uses a standard 6-bolt mounting interface. As long as your current hubs are compatible with 6-bolt rotors, this will fit.
Yes, the updated brake track design is optimized for better pad contact, which significantly reduces vibration and noise compared to older rotor designs.
The HS2 is designed to work with most mountain bike brake pads, but it performs best when paired with SRAM’s high-performance compounds. Always ensure your pads are compatible with the rotor material for the best longevity.
The specialized coating helps the rotor shed heat more efficiently during heavy braking. By managing heat better, the rotor maintains consistent performance and prevents brake fade on steep or technical trails.
