SRAM Introduces Their All-New HS2 Rotor 2

A completely new design and increased thickness for improved heat management and a quieter ride.

SRAM Introduces Their All-New HS2 Rotor

SRAM has released their new mountain bike specific HS2 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.

HS2 Rotor Details

  • Thicker 2.00mm rotor 
  • Superior heat management (40°C less than Centerline, per Garda test)
  • 7% more power
  • Available in 6 bolt and Center Lock (lock ring not included)
  • MTB specific
  • Sizes: 160mm, 180mm, 200mm, 220mm
  • Material: Steel
  • Price: $50-65 USD

The past few weeks we've had the chance to grab a handful of brake and see how SRAM's new HS2 rotors perform. So far the changes in performance have been subtle but beneficial when compared to SRAM's current Centerline rotors. For reference, all of our ride time has been spent on dual 200mm rotors with Code RSC brakes and metallic pads.



The most notable improvement the HS2 rotors provide compared to the previous SRAM Centerline rotors is the lack of any vibration noise due to the 2.00mm thickness. Most riders have had a rotor that vibrates and hums from either braking forces or trail chatter. The latter being the most frustrating as you aggressively shake your rotor and check rotor bolts to find no obvious noise culprit exists. The increased thickness of the HS2 rotors have greatly improved stiffness and helped eliminated most rotor noise. This includes both rotor humming under heavy braking as well as rotor vibration noises when pedaling over rough sections of trail. While we did not bang the RS2 rotors against any rocks while riding, we would bet the added material should improve rotor durability against impacts. Similarly, it's worth noting that updates to the brake track pattern should extend brake pad lifespan due to increased heat management. So far we have not ridden the rotors for long enough to witness any signs of wear or experience improved brake pad longevity.  


The HS2 rotors have an entirely new design with some of the rotor spokes utilizing thermal dissipating paint for heat management. Have our Code RSC brakes performed exponentially better at managing heat and brake fade when compared to the Centerline rotors we were riding previously? We would be lying if we said a huge difference was noticeable. However, we trust the testing SRAM performs and a 7% increase in power, while marginal, is happily welcomed. We did not have issues with overheating or brake fade with our previous SRAM rotors and thus far have experienced the same consistent, sharp bite and lever throw with the RS2 rotors. What we know for sure is the flat black dissipating paint looks pretty badass contrasted against the shiny steel braking surface. Overall, the RS2 rotors have managed heat with ease, providing plenty of stopping power while the increased noise cancellation and durability of the 2.00mm thickness has been the standout improvement over previous SRAM rotors.
