That shifting is the reason I love eTap. With a "blip" I can do all my shifting right handed. It's amazing.

I don't think the two button front shifting was to get around anyone's patents, it was just a way to get shifting for front and rear with just two buttons available to the user. There are only so many ways you can control three different things (rear up, rear down, toggle front) with just two buttons. With autorepeat already assigned to a long press, chording is pretty much the only thing left.

As it is, the old eTap did allow you to shift the front with a single button. The problem was that button was either on the side of the derailleur, or on the BlipBox controller, so you couldn't do it from their brake levers.

From what I hear, the new AXS app allows you to assign a front shift to a single button if you add a blip to your levers, getting around the two button limitation.

Fortunately, Campy beat SRAM to the 12 speed road bike system and the cassette fits on the same hub as 9/10/11 speed. For me, the only thing I'd gain over my modestly priced Chorus 11 group is an 11T cog, that I don't need. My 50/34 with a 12-32 does a great job on very steep hills and mountain roads. I expect a Chorus 12 group, next year. I could convert my 11 speed bike to Record 12 with only the shifters, derailleurs, chain and cassette for under $1000.
