The big issue I have with electronic shifting is the lack of triples crank options that are not custom blends of road and mountain components with a hacked cpu. Gear range and ratio gaps is a big deal for some who have ridden well set up triples for decades.

I look at the Dia Comp guidonnet levers and the first thing I think of, which is the same for highly shimmed drop bar levers, is the amount of cable pull before the levers bottom out against the bars. Back in the day these types of levers didn't have cable pull concerns to anywhere the same degree of today's brake calipers/linear pulls do.

As I said before bar end shift levers are a great option. They free up the brake lever choices from having to handle the shifting too. Andy.
