The Sram HS2 is a completely redesigned brake disc with excellent heat management properties. This is achieved through a 2 mm thick design that can absorb more heat without losing braking efficiency. Combined with a slightly circular construction, it offers excellent stiffness, eliminating problems related to frequently warped discs. Additionally, the spider is coated with heat-dissipating paint, providing better cooling. The braking surface works perfectly with the pads, while its shape allows for quiet and efficient braking without excessive pad wear. The rounded edges reduce the risk of injury.
