Shimano B05S-RX Disc Brake Pads and Spring – Resin Compound

The Kool-Stop D175E is an e-bike-specific disc brake pad designed for Magura systems that see higher speeds and heavier loads. It uses an organic friction compound paired with a ceramic heat barrier to help manage heat during long or repeated braking.

This pad is a good option for riders who want smooth, predictable braking with better fade resistance than standard organic pads on modern e-bikes.

Key Features
• E-bike-specific organic compound
• Ceramic layered heat barrier to limit heat transfer into the caliper
• Designed to reduce brake fade under higher speed and load
• Consistent, controllable braking feel
• Steel backing plate for durability

Compatibility & Use Notes
• Pad Style ID: 41
• Compatible with:
– Magura MT Thirty
– Magura MT5 Next
– Magura MT7 Next
• Organic pad material
• E-bike compound
• Not compatible with other Magura pad shapes or non-listed calipers

Service / Ownership Context
E-bikes place higher demands on braking systems. Proper bed-in is critical for heat control and pad life. Inspect pad thickness regularly and replace before the backing plate is exposed to protect rotors and maintain braking consistency.

Fit & Use Signals
• You ride an e-bike with compatible Magura MT brakes
• You want quieter, more controllable braking
• You need better heat management than standard organic pads
• Not a fit if your Magura brake uses a different pad shape
• Not a fit if you prefer metallic or sintered pads
