Electronic shifting will evolve like index shifting evolved. People questioned why we needed index shifting in the mid-1980's I can shift fine without index shifting. Index shifting will be a pain in the @$$ to keep working. We all worked through that & lived to tell about it. Suntour didn't & Campagnolo almost didn't but that is another story. Electronic shifting will probably take years to work out all the bugs & find it's own direction. I don't want to be the first guy to buy the stuff. Imagine the possibilities!!! Seamless gear changes. Shift buttons built into your gloves. 20+ cog cassettes or 5 front chainrings. I think it will happen & we will be better off for it! Just take a look back at history.
