The Shimano GM02 Di2 E-Tube Frame Grommets are small components of Shimano's electronic Di2 shifting system for road bikes. They are designed to be used in conjunction with the E-Tube wiring system to neatly route and protect the Di2 wires as they pass through the bike's frame.
The grommets come in a pack of four and are designed to fit a variety of frame sizes and shapes. They have a simple snap-in design that makes them easy to install and remove, and they are made of durable materials that ensure long-lasting performance.
The Shimano GM02 Di2 E-Tube Frame Grommets are available in a range of sizes, which allows riders to choose the best fit for their particular frame. They are compatible with a wide range of Shimano Di2 components, including the shifters, derailleurs, and battery.
