Mountain Bike Road Bike Disc Brake Pad Middle-Sized Central Lock Disc 160mm 180mm Stainless Steel RT30 Lock Disc Brake Pad
RT30 Central Lock Disc Brake Pad for Mountain and Road Bikes 160mm 180mm

This middle-sized lock disc brake pad is a direct-replacement component for cyclists who need a reliable, no-fuss brake disc. Designed for mountain bikes and road bikes, the pad uses a central lock mounting system for easy installation and secure fit. The stainless steel construction offers dependable braking performance without the added weight of heavier alternatives. Available in 160mm and 180mm outer diameters, it allows you to choose the right size for your wheel and riding style. The 1.8mm thickness provides a consistent braking feel whether you are commuting, riding trails, or training on the road.
Features and Construction

The brake pad is built around a simple, durable stainless steel disc. The central lock interface ensures compatibility with many modern bike hubs, making it a practical upgrade or replacement part.
Material and Build
Made entirely from stainless steel, the disc resists corrosion from moisture, mud, and road salt. The 1.8mm thickness offers a balanced combination of rigidity and weight, contributing to steady braking performance without excessive rotor flex.
Size and Practical Fit
You can choose between the 160mm and 180mm diameter versions. The 160mm disc weighs 170g, ideal for lighter road or cross-country setups. The 180mm disc weighs 188.6g, providing extra braking leverage for heavier riders or more demanding terrain. Both sizes share the same 1.8mm thickness and central lock pattern.
Uses and Placement

This brake pad is suitable for front or rear wheel positions on bikes equipped with a central lock hub. It is a versatile choice for both on-road and off-road cycling.
Event or Professional Use
For competitive cyclists or event riders, the consistent braking feel and low weight make the 160mm version a good option for road races or cross-country events. The 180mm version offers additional heat dissipation and stopping power for downhill stages.
Everyday Home Use
For daily commuting, recreational riding, or gravel loops, either size works well. The stainless steel finish is easy to clean and does not require special maintenance beyond standard brake care.
Benefits and Buying Value

The brake pad offers straightforward value as a replacement part that matches original specifications. Its simple design reduces the chance of compatibility issues.
Reuse and Low Maintenance
The stainless steel disc does not require frequent replacement under normal use—only when worn or damaged. Cleaning with a mild degreaser and a soft cloth keeps the braking surface effective without special tools.
Why Choose This Product
This disc brake pad gives you a direct, central lock replacement without the complexity of multi-material or lightweight composite rotors. The choice of two diameters lets you tailor your braking performance to your bike and riding style, all at a reasonable weight and with reliable stainless steel construction.
