If your brake caliper uses Shimano L-Type or K-Type pads, these will fit.

Gorilla Brakes Factory Racing Organic Disc Brake Pads are purpose-built for riders who prioritise ultra-quiet braking, immediate bite, and refined lever feel over pad longevity. Using an extremely soft, non-metallic organic racing compound bonded to a lightweight silver backing plate, these pads deliver instant performance in dry conditions with minimal noise.

This is a specialist race-focused compound. Pad wear will be significantly faster than other Factory Racing options, particularly in wet, gritty, or abrasive conditions.

⚠ Important Usage Information

  • Optimised for dry weather road and gravel riding
  • Extremely fast wear in wet, muddy, or winter conditions
  • No bedding-in required — full braking performance immediately
  • Not designed for riders prioritising long pad life
