Shimano BP-G05S-RX / BP-G05A-RX Disc Brake Pads

Shimano G-Type 2-Piston Resin Disc Brake Pads (G05S Steel / G05A Aluminium)

Restore quiet, highly controllable stopping power to your bike with genuine Shimano G-Type 2-piston resin replacement disc brake pads. Serving as the modern successor to the widely popular G02A, G03A, and G03S models, the updated G05 resin compound delivers up to 50% better wear resistance than previous generations without losing the smooth modulation resin pads are known for.

This listing offers two backplate options in individually sealed retail packaging: the robust G05S-RX (Steel Backplate) for maximum durability, and the lightweight G05A-RX (Aluminium Backplate) for improved heat dissipation and reduced weight.

Backplate Options

1. G05S-RX — Steel Backplate (Durable & Value-Focused)

• Backplate Material: Steel

• Characteristics: Extremely tough structural backing designed for everyday riding, commuting, and general trail use. Offers high strength and consistent piston engagement at a great value.

2. G05A-RX — Aluminium Backplate (Lightweight & Heat Management)

• Backplate Material: Aluminium

• Characteristics: Saves weight while active thermal dissipation helps draw heat away from the braking surface, reducing thermal fade during longer descents.

Key Features

• Upgraded G05 Resin Compound: Offers approx. 50% greater wear durability compared to G03-series pads, giving you more miles between pad swaps.

• Quiet & Modulated Braking: Organic resin formula provides excellent bite right from cold lever pulls with minimal noise or rotor shudder.

• Aluminium vs. Steel Choice: Select Steel (G05S) for robust everyday use or Aluminium (G05A) for lighter weight and enhanced cooling performance.

• Individual Retail Set: Includes 1 pair of pads (for 1 caliper), 1 pad spring, and 3 split pins (cotter pins).
