Shimano L05A-RF Disc Brake Pad and Spring
What Brake Systems Use the Shimano L05A-RF Disc Brake Pad?
The L05A-RF is a resin compound disc brake pad with alloy cooling fins for Shimano's hydraulic flat-mount road and gravel disc calipers using the L-series pad shape, specifically the BR-R9270, BR-R8170, BR-R7170, and related flat-mount calipers from the current 12-speed road Di2 generation. The resin compound provides smooth, progressive modulation with low noise across dry and wet conditions, which is the preferred performance character for road and gravel riders where controlled feel and quiet operation take priority over maximum bite. The L05A-RF delivers approximately 50 percent more wear resistance than the previous L03A generation, extending service intervals without any compromise in braking character.
The alloy radiator cooling fins on the RF version's backing plate function as a heat sink, drawing thermal energy away from the pad and caliper piston during braking. This is particularly useful on longer road descents or loaded gravel rides where sustained braking input would otherwise build heat in the system and begin to degrade lever feel. The fins also help extend overall pad life by reducing the thermal cycling the compound undergoes ride to ride. Each package contains one pair of pads with springs. The L05A-RF is the correct finned resin pad for the current 12-speed Shimano road Di2 flat-mount caliper lineup, and it is also compatible with the Dura-Ace R9270 and Ultegra R8170 calipers in that generation.
