ST-R9120 Funnel Adapter & O-Ring

Shimano is renowned for its high-quality bicycle components that enhance performance and durability. Their innovative technology ensures smooth shifting, reliable braking, and overall improved cycling experience. Choosing Shimano means investing in a brand trusted by cyclists worldwide.

A bleed funnel is essential for maintaining hydraulic brake systems. It helps remove air bubbles from the brake lines, which can compromise braking efficiency. By using a bleed funnel, you ensure that your brake fluid is free of air, leading to more responsive and reliable braking.

The brake lever is a crucial component that allows you to control your bike's braking system. Located on the handlebars, pulling the brake lever engages the brakes, enabling you to slow down or stop safely. A well-designed brake lever enhances comfort and control while riding.

An adapter, like the Shimano ST-R9120 Funnel Adapter, is necessary for connecting the bleed funnel to the brake lever bleed port. This connection simplifies the maintenance process, ensuring that you can effectively bleed your brakes without any hassle, ultimately improving your bike's performance.

An O-ring is a vital component that creates a tight seal between the funnel adapter and the brake lever bleed port. This seal prevents brake fluid from leaking during maintenance, ensuring that your brake system functions optimally and maintains its performance over time.

Many cyclists can perform basic brake maintenance, including bleeding the brakes, using the right tools like a bleed funnel and adapter. However, if you're unsure or uncomfortable with the process, it's always a good idea to consult a professional to ensure your brake system is properly maintained for safety and performance.
