We are going to be starting a series within our shop journal called BBD (BUILD BREAK DOWN). We will be covering full and partial custom builds. We are hoping to do this for every custom build. So we hope you'll like it!
Oct. 30th, 2017 - Cervelo S5 Di2 6870
This customer brought us a repaired Cervelo S5 frame and wanted to do a simple Ultegra 6870 Di2 build. Instead of having the typical Di2 build where you have the Junction Box A on the stem with exposed eTubes, he chose to upgrade to the new Shimano DI2 EW-RS910 3-Port e-Tube junction. This junction box allows you to install it in the frame or in the bar end of your handle bars for optimized integration. It also looks really good too.
EW-RS910 hanging out during mock-up. It will be inserted and secured where you typically put your bar end plug.
The cockpit is wired up before installing it back onto the bike. e-Tubes are ran through the bars.
We test the system to make sure everything works and shifts before securing the cables and wrapping the bars.
We use heat shrink tubing to wrap the brake cable and e-tube together which goes directly into the frame.
Bars are wrapped - This upgrade gives you a very clean look without compromising functionality.
