Shimano 105 Di2 Install | Full Mechanical-to-Di2 Conversion (Specialized)

In this video, I convert a nearly-new road bike from Shimano 105 mechanical to 105 Di2, including a dull strip down to the bare frame and installation of an SL7 stem conversion. This is a full workshop install, not a quick overview. I cover the details that usually get glossed over, including internal routing, brake setup, and final Di2 configuration. What’s covered: Stripping the bike to a bare frame SL7 stem conversion and new handlebar Installing Shimano 105 Di2 from scratch Internal hose and Di2 wire routing Brake hose cutting, olive/barb install, and bleed Junction placement and battery install Firmware updates and Di2 setup Final adjustment and checks If you’re planning a mechanical-to-Di2 conversion, or you want to see how this job should be done , this will walk you through the entire process step by step.
