Great website Terry. It is very informative and easy to follow.
Slight thread hijack. I was looking into getting a di2 groupset for my rim brake bike, but after reviewing your website I am like ***. For Rim brake I have to run internal wires from from shifters to the battery, then from the battery to the derailleurs? Also, if I don’t have internal wire capable handlebars, I need a junction box….***.
Shimano di2 is not wireles as I thought. It easier to get r8000 components and run mechanical like the old times.
