I suppose I am not surprised to see so many 50 plusers rejecting the idea of electronic shifting. But if the question is asked in the racing forum, even the masters' racing forum, one gets a much more uniformly positive response. Excellent reliability, greater precision, battery life that is exceptionally long and gives plenty of warning of the need to recharge, the ability to move all the way up and down the block instantly if required.. . I've borrowed a Di2-equipped bike to try it and the advantages seem real and would definitely confer a benefit when racing.

So if I keep racing, as I intend, then Di2 or more probably Ui2, will definitely be in my future. I would have had it installed on the custom bike I'm currently having made, but I won't be racing that bike and I had a triple groupset sitting around that I had picked up cheap, so decided against it. I share some of the sentiments of those who say "yes, but the point of a bike is is simplicity", but really, I'm riding a carbon-fibre bike with aerodynamic carbon race wheels and twenty gears shifted by indexed integrated units. Or, on another bike, a Rohloff planetary hub gear with 14 gears that is a positive miracle of engineering. It seems eccentric to adopt every advance except the most recent. When I want simplicity I can always get on the fixed gear.
