If your brake caliper uses Hope E4 or RX4+ pads, these will fit.
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. Using an ultra-soft, non-metallic organic racing compound bonded to a lightweight
backing plate, these pads are tuned for dry-condition performance across road, gravel, CX,
and trail riding.

🔥 Compound: Factory Racing Organic
Factory Racing Organic is the fastest-biting and quietest compound in the Gorilla Brakes range.
