E-Tube Di2 Wire

The Shimano E-Tube Di2 Wire plays an integral and important role in assembling your 6770, 6870, or 9070 Di2 group. Without it, you can't install your Di2 derailleurs, shifters, or battery. So, check the size chart on this page for length, and don’t worry about the rest. If you’re running Ultegra 6770 or 6870, or Dura-Ace 9070, this E-Tube Di2 Wire will connect up all the moving parts. Its connectors are the same, regardless of application, so all you have to do is choose the length that’s best suited.

        This is the wire you need to install your Di2 group. It's a critical component of one of the best gruppos ever made.

        Straight Forward

        • Familiarity: I've put it through the wringer

        Shimano's e-tube wires work flawlessly. After a few Di2 set ups over the past couple years I have had zero issues.

        Durable wire!!

        • Familiarity: I've put it through the wringer

        It's the only wire you can get for connecting di2 components, but the quality is there, great and very durable.

        shockingly durable little wire that connects your components

        A little long for the D-Fly

        • Familiarity: I've used it once or twice and have initial impressions

        Purchased this to connect the D-Fly until to the rear derailleur. it is a little long. It would be great if CC stocked the 250 mm or 200 mm lengths

        they have 250, but not 200mm - bummer!

        E-Z does it.

          Electronic shifting...it's a thing of beauty! You'll need a few of these to complete any Di2 setup. If you have any questions on what you need, please give our customer service "Gearhead" team a call!


          no issues

          connections seem very secure and fits great inside my bike. I would certainly purchase this item again!

          About as easy as it gets

          • Familiarity: I've put it through the wringer

          Even though the E-Tube wiring has been around for a while, I still hear fears of use and concerns about durability. I've had the good fortune to build, test and unfortunately crash E-Tube equipped bikes for a couple years now and between the ease of setup and surprising durability of the system, I'm constantly impressed by how well it works. Wireless is the future, but until then we're in good hands!

          • Familiarity: I've used it several times

          i am amazed how robust this wire is and how well it fits neatly inside the frame. i was kind of hesitant about electrical wire on a road bike. but shimano did a great job of building very robust protective shield around the major wires for protection. it is not easy to cut one of these wire's unless you deliberately set out to do just that. Good product and it looks like it will last a long time.
