The cooling fins of the Jagwire Elite Cooling pads allow heat to dissipate from the brake system. The light top and side cutouts allow you to maximize the convective cooling air flow.The semi-metallic compound combines the best features of organic and sintered pads. It allows a better modulation of the braking and is less noisy than the sintered metal compound, also lasting longer and providing better performance in the wet than the organic compound.Graphene is used as a thermal conductor to allow the heat to dissipate, passing through the fins cooling. By transferring heat from the brake disc and braking surface, screeching and wear of the rotors is prevented.COMPATIBILITY:- Shimano XTR M9120- Shimano Deore XT M8120- Shimano SLX M7120
