A good choice for riders servicing a compatible Shimano 2-piston brake who want quieter braking, smooth modulation and improved pad life over earlier G-series resin pads.
The Shimano G05A-RX is a replacement disc brake pad set for compatible 2-piston Shimano calipers. Its 5th-generation resin lining is designed to reduce braking noise while providing smoother modulation, helping you apply braking with a more controlled, predictable feel.
The updated resin friction material offers 50% better wear resistance than G03A and 110% better than G02A, making this a sensible upgrade or service replacement for regular road, gravel, cyclocross and mountain bike use where quiet operation and control matter. The alloy back plate keeps the pad construction lightweight.
This pack contains one pair of pads to equip one brake caliper, supplied with the spring and split pin. It is the narrow-type G shape and has no radiator fin, so check your caliper model against the compatibility list before ordering. Compatible examples include Shimano BR-M8100, BR-M8000, BR-M7100, BR-M7000, BR-M6100, BR-M6000, BR-MT600 and BR-U8000, among others.
