Compact 2-Port SD300 Junction for Modern Di2 Setups

Description

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.

Features
  • Optimized for SD300 E-Tube Systems: Specifically designed for Shimano’s next-gen Di2 components, ensuring reliable signal transfer and power delivery.
  • Compact In-Line Design: Slim profile easily fits inside handlebars, frames, or junction boxes for a clean, professional finish.
  • Lightweight and Discreet: Adds minimal weight while providing essential connectivity in advanced Di2 configurations.
  • Secure and Weather-Resistant Ports: Two SD300 ports deliver a tight fit with protection against dust, water and vibration for long-term durability.
  • Critical for Firmware Sync and Extensions: Enables wireless shifter integration and system updates, making it essential for custom builds and future-ready bikes.
