Even though a lot of you seem to resist the idea. We WILL be using it across all product lines within the next 10years or so. Its a natural progression like index shift was 20 years ago. Most people that have it that I've spoken to love it. Batteries last over a year. Right now it's just expensive.
Ultegra gets electric shifting in 2012.
