Shimano B05S-RX (Resin)
The New Standard for Silent Stopping.
The Shimano B05S-RX is the direct successor to the popular B01S and B03S pads. Engineered for riders who value a quiet drivetrain and predictable stopping power, these resin pads feature a completely new friction material. They are designed to deliver smooth modulation and a high "bite" factor in both wet and dry conditions, making them the most reliable choice for everything from urban commuting to light trail riding.
Why the B05S-RX is the Ultimate Maintenance Upgrade:
- 50% Better Wear Resistance: Thanks to the 5th-generation resin compound, these pads last 50% longer than the B03S and a massive 110% longer than the original B01S, giving you more time on the bike and less time in the stand.
- Whisper-Quiet Braking: Resin pads are known for being much quieter than metallic alternatives. The B05S-RX is designed to eliminate the "howl" often associated with disc brakes, providing a silent and refined riding experience.
- Exceptional Modulation: The "wide" pad shape and flexible compound allow for precise control over your braking force. You can easily feather your brakes on tricky descents without the "on/off" feeling of more aggressive race pads.
- Stainless Steel Backing: The pads are mounted on a rigid stainless steel back plate, ensuring consistent pressure across the entire friction surface and preventing corrosion over time.
- Universal Compatibility: This is Shimano’s most common pad shape, fitting a huge range of Shimano calipers (Deore, Alivio, Acera, Nexave) and many 3rd-party brands like Tektro and TRP.

The Alegro Perspective: We call the B05S-RX the "peace of mind" pad. It’s the one we recommend most because it just works. It doesn't squeak, it doesn't chew up your rotors, and with the new 5th-gen compound, it lasts impressively long. It’s a small, affordable part that makes a massive difference in how confident and quiet your bike feels.
Silent Power. Extended Durability. Trust the Precision of Shimano.
