Green Press Fit Retaining Compound - 10ml

A Press Fit Retaining Compound is a specialized adhesive designed to securely bond non-threaded parts, like bearings and bottom brackets, in your bicycle. It fills gaps between components, creating a strong bond that prevents movement and noise during rides. Using this compound ensures that your bike parts stay in place, enhancing performance and safety.

The Bottom Bracket (BB) connects your bike's frame to the crankset, allowing the pedals to turn smoothly. A press-fit BB is inserted into the frame without threads, relying on a tight fit to hold it in place. This design can reduce weight and improve stiffness, making it a popular choice for performance-oriented cyclists.

The AP-1 Adhesive Primer is a preparatory product that cleans and prepares surfaces before applying a retaining compound or threadlocker. Using this primer enhances the bond between components, ensuring a stronger and more reliable connection. It’s highly recommended for optimal performance and to prevent parts from becoming stuck together.

Threadlockers are adhesives specifically designed to secure threaded fasteners, like screws and bolts, preventing them from loosening due to vibrations. Unlike retaining compounds, which are used for non-threaded parts, threadlockers are essential for maintaining the integrity of threaded connections in your bike, ensuring everything stays tight and secure.

Sealed Bearings are designed with a protective casing that keeps dirt and moisture out, which is crucial for maintaining smooth movement and reducing friction in your bike. By using sealed bearings, you enhance your bike's performance and longevity, as they require less maintenance and are less likely to fail due to environmental factors.

While Press Fit Retaining Compound is excellent for securing non-threaded parts like bearings and bottom brackets, it is not suitable for all components. It’s specifically designed for parts that require a strong bond without threads. Always check the manufacturer's recommendations for each component to ensure you’re using the right adhesive for the job.
