Not for me..

I had a Di2 flatbar bike back in 2013 and while it was nice, I find that I like good old mechanical shifting better. I had that bike for 4 years and put 10's of thousands of miles on it and I never had any issues or expenses associated with it.. It was basically maintenance free other than I needed to go to bike shop for firmware updates and remember to charge the battery every 4 months or so.. I believe the system that was on my bike was actually called Ui2 from Shimano...
