Shimano has had electronic shifting since its DI2 series. Not that there’s anything wrong with SRAM ...
Anyone with a cellphone can tell you battery life is an issue. While wireless shifting is interesting I think
a smooth shifting under load and some feedback on what the shift is more important.
I also had a bike that didn’t want to die, a steel alloy Fuji 21 speed, 3 chainrings, lots of duplication in the gears and heavy.
I like the idea on 11 or 12 gears and only one shifter.
I do not trust electronic shifting. Race teams are staying away from it.
