Durable, reliable, clean, what more can you ask for?

Easy to use, snap in place securely, and durable.

It's easy to install and it makes sure your derailleur shifts when you want it to.

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

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

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

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

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!

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

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!

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.
