The RISK RL224 / RL309 Hydraulic Brake Bleed Funnel Adapter is designed to convert compatible MTB brake bleed funnels for use with Shimano road hydraulic shifters.
This adapter allows riders and mechanics to use a mountain bike-style oil bleed funnel on compatible road hydraulic brake levers, making brake bleeding and oil replacement more convenient.
Made from lightweight aluminum alloy with anodized blue finish, the adapter features an M7×P0.75 external thread and M5×P0.8 internal thread. Each set includes 1 adapter and 1 O-ring.
The RL224 is the old version, while the RL309 is the upgraded version with wider compatibility for newer road hydraulic shifters.
