Shimano BP-J05A-RF Resin Disc Brake Pads

Shimano J-Type Resin Disc Brake Pads (BP-J05A-RF / EBPJ05ARFA)

Keep your mountain bike stopping with confidence using genuine Shimano BP-J05A-RF resin disc brake pads. Designed as the direct successor to the popular J02A and J03A models, the J05A utilises an advanced resin compound that delivers approximately 50% better durability than previous generations without sacrificing quiet, highly controllable stopping power.

Featuring Shimano’s Ice-Technologies radiator cooling fins paired with an aluminium backplate, these pads actively pull heat away from the caliper and rotor. This thermal dissipation minimises brake fade on long, steep descents, preserves pad compound life, and delivers smooth, predictable modulation across technical XC, trail, and trekking terrain.

Key Features

• Advanced Resin Compound: Delivers a smooth, quiet initial bite and reduced rotor wear with up to 50% greater durability than predecessor models (J02A / J03A).

• Ice-Technologies Cooling Fins: Integrated aluminium cooling fins channel airflow and quickly dissipate heat to eliminate brake fade during sustained descents.

• Aluminum Backplate: Lightweight construction provides excellent thermal conductivity and solid structural stability under heavy braking.

• Narrow Pad Shape: Purpose-built for 2-piston MTB and Trekking post-mount/IS disc brake calipers.

• Individual Retail Packaging: Comes individually packed in official Shimano retail blister packaging, including 1 pair of pads, 1 spring, and installation hardware.

Recommended Disciplines

• Mountain Biking (MTB): Cross-Country (XC), Trail, and All-Mountain riding.

• Trekking & E-Bikes: Ideal for high-demand commuting and trekking setups requiring reliable thermal management.
