Compatible with TRP DH-R EVO, Trail EVO, Quadiem, and G-Spec 4-piston calipers — engineered for riders who prioritise ultra-quiet braking, refined lever feel, and immediate bite in dry riding conditions.
Gorilla Brakes Factory Racing Organic Pads use an ultra-soft, non-metallic organic racing compound bonded to a silver back plate. This compound delivers instant braking response, smooth modulation, and near-silent operation with no bedding-in required.
These pads are mechanically compatible with TRP gravity and trail braking systems. However, due to the extremely soft racing compound, pad wear will be significantly faster than other Gorilla Brakes compounds, especially in wet, muddy, abrasive, or high-heat conditions.
⚠ Important Usage Information

Didn't make a huge difference compared to Shimano H03A. Better bite but no change on the braking power (not yet tested on harsh conditions/long downhill
