Shimano Di2 Upgrade Project: Giant TCR Road Bike Dura-Ace Di2 Conversion

This week I upgraded my older Giant TCR from mechanical Shimano Dura-Ace 9000 to Dura-Ace Di2 9070 (the electronic equivalent). I sourced the groupset from a Facebook ‘Triathlon For Sale’ group for a lot less than retail. This video covers the process I followed for the upgrade. It’s not a full A-to-Z how-to but it’ll give you a good overview of what it takes to do this update yourself on a budget.
