Gorilla Brakes Factory Racing Organic disc brake pads are engineered for riders who prioritise instant bite, refined lever feel, and ultra-quiet braking over pad longevity.

Pad Type Brake Series Caliper Model Riding Discipline

🔥 Compound: Factory Racing Organic

Factory Racing Organic is the fastest-biting and quietest compound in the Gorilla Brakes range. It delivers immediate friction with no bedding-in required, extremely smooth modulation, and minimal rotor abrasion. This compound is intentionally tuned for race feel rather than lifespan.

Feature Benefit
Ultra-soft organic compound Instant bite with near-silent braking
No bedding-in required Full performance from the first ride
Low rotor abrasion Minimal rotor wear
Race-focused tuning Refined lever feel and smooth modulation
Short service life Designed for performance, not longevity

Note: This compound wears significantly faster in wet, muddy, gritty, or winter conditions and is not intended for riders prioritising pad life or heat resistance.

  • 1 × Pad spring clip
  • Minimal, recyclable packaging
