Want better braking? Of course you do. If it’s a matter of simply running a better rotor for improved performance, sign us up. That’s what SRAM is claiming to offer with their newest brake rotor, the HS2.
Meant specifically for mountain biking, the HS2 claims to offer 7% better power. That increase comes from things like a new brake track design that is said to “increase pad traction.” It looks like it would also be quieter as well.
The rotor itself is now thicker at 2.00mm, which when combined with the special heat dissipating paint, leads to a rotor that runs cooler when compared to the previous Centerline model. According to SRAM’s testing in Garda, the new HS2 rotor ran up to 40°C cooler. Additionally, the edges of the rotors are rounded.
