It comes in Centerlock and IS 6-bolt versions.
The all-new SRAM HS2 Rotor is a mountain bike-specific rotor designed to improve brake performance while reducing noise and increasing heat dissipation. Featuring a new brake track pattern for increased pad traction and recessed spokes with thermal dissipating paint, the HS2 is a more powerful, quieter rotor with best-in-class heat management.
They come in Centerlock or IS 6-Bolt interfaces and 160, 180, 200, and 220mm diameters at $50, $55, $60, and $65, respectively. Note that the Centerlock version does not include the lockring.
Note the recessed spokes with darker thermal dissipating paint
The HS2 rotors have a 2.00mm thickness, compared to their Centerline predecessors, 1.85mm. The increased thickness, additional braking surface area (smaller cutouts), and special heat-dissipating paint on the spoke arms are supposed to provide cooler running rotors.
According to SRAM’s testing in Garda, the new HS2 rotor ran up to 40°C cooler than the previous Centerline rotors.
- Superior heat management
- 7% more power
Thoughts => Obviously, making a thicker rotor with more surface area will help dissipate heat and offer improved power. I am not sure if the spokes thermal dissipating paint and recessing will help with any of that, but it sounds intriguing? Will all this new design off more power, less heat, and noise? Real-life testing will be the only basis to see how it all works.
