SRAM HS2 Centerlock Disc Brake Rotor - 160mm, 2mm Thick, Improved Heat Management

Upgrade your mountain bike's braking power and heat management with the SRAM HS2 rotor. This isn't your standard thin rotor – it's a full 2mm thick (most are 1.8mm). That extra mass, combined with a special thermal paint on the spokes, helps it absorb and dissipate heat way better, which means more consistent power on long, steep descents without the brakes fading.

SRAM says it can provide up to 7% more braking power compared to their previous rotors. It uses the Centerlock mounting system (and includes the lockring) and is 160mm in diameter – a common size for front or rear wheels. A heads-up: because it's 2mm thick, make sure it has enough clearance in your bike's brake caliper before buying. If you're a serious rider who pushes hard on the trails, this rotor is built to handle the heat and give you more control.
