SRAM Avid X0 Trail Brakes are designed to slow you down in a hurry and nothing contributes to that more than the pads. These SRAM AVID Organic Disc Brake Pads provide strong braking power that's best suited to dry riding conditions and ensures quieter braking when compared to metal sintered pads. For hot Australian conditions, you will definitely get more bite and smoother braking with Organic pads, though for extended downhill trails where your brakes run very hot, the Metallic pads are the better choice.
