Hacking My Di2 For Endurance Racing

In 2015 I did the 4,200 km Transcontinental Race from near Brussels to Istanbul. Since that wasn’t quite long enough I also did a warm up by riding 2,800 km from Istanbul to the start line. Great holiday, but there was one unintended consequence: by the time I got to Greece (6,000+ km) my hands had stopped working. When I had to pay for something I’d hold out the money in my palm and apologetically ask people to take the money. I recovered quickly after the race, but decided that I’d upgrade my bike to Di2 with electronic shifting.

It was a great idea, but as anyone who is a reader of this blog knows, I’m never satisfied and I decided that I needed to modify the Di2 to put in shifting buttons both on my aero bars but also under the handlebars. This would give me three different options for shifting depending on where my hands were. This is a geeky post to show how it is done. Not only is it a lot less expensive than the $200+ for Shimano’s offering of bar end shifters, or $100 for a bulky ‘climbing’ shifter (parts cost me $40), but it’s a much tidier solution as well (especially compared to the climbing switch).
