Was able to update software with no issues. ### ⭐⭐⭐⭐⭐ Di2 *by M***N on January 8, 2024* Works perfect ### ⭐⭐⭐⭐⭐ Used to update Di2 firmware *by B***N on September 23, 2023* This, paired with a "SHIMANO EW-JC302 Di2 2-Port Junction Black, One Size", allowed me to connect to the battery via the unplugged front derailleur cable. Once connected, the shifters become "wired" and can be updated individually. You may also want to grab a TL-EW300 Cable Tool to make the process a bit easier. ## Frequently Bought Together - SHIMANO 2Nd Gen E-Tube Di2 Wire - SHIMANO 2 PORT JUNCTION EW JC302 SD300 PORT X 2 - SHIMANO Cycling Y7HE40000 TL-EW300 Cable Tool - Replacement Spare Parts for Bike --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/288286866-shimano-2nd-gen-e-tube-di2-wire-ew-sd300-1600mm](https://www.desertcart.jp/products/288286866-shimano-2nd-gen-e-tube-di2-wire-ew-sd300-1600mm) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-03*
