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 Alfine S700- Shimano Deore M615- Shimano Deore M6000- Shimano Deore XT M785- Shimano Deore XT M8000- Shimano Deore XT M8100- Shimano Non-Series Road R785- Shimano Non-Series Road RS785- Shimano SLX M666- Shimano SLX M675- Shimano SLX M7000- Shimano SLX M7100- Shimano XTR M985- Shimano XTR M987- Shimano XTR M9000- Shimano XTR M9020
