The Shimano EW-JC302 is a compact 2-port inline junction designed for SD300 E-Tube systems. It enables easy extension of wiring between Di2 components, offering a tidy and efficient solution when additional cable length is needed—especially in internally routed frames.
Designed for Next-Gen Di2 Systems: Fully compatible with Shimano’s SD300 wire standard, this junction is built for use in newer 12-speed Di2 setups. It ensures consistent signal transfer and power distribution, helping maintain the precision and reliability Shimano electronic drivetrains are known for.
Compact and Lightweight Build: Weighing just a few grams, the EW-JC302 is practically invisible once installed. Its slim, in-line design fits neatly within handlebars, downtubes, or junction boxes, making it perfect for clean, professional-grade builds where space and aesthetics matter.
Durable and Secure Connections: Equipped with two SD300 ports, the junction offers a snug and secure fit that resists water, dust and vibration. It’s engineered for long-term reliability on road, gravel, or MTB bikes—where exposure to the elements is part of the ride.
Beyond extending cable length, the EW-JC302 also plays a critical role in connecting wireless shifters or secondary components to the main system for firmware updates.
