Yep, I like that SRAM is thinking past the limitations of cables. I always did wonder why Shimano had an The one concern I have is that the chainring shift method precludes use of the system for adaptive cycling by athletes who lack the use of both hands, and will make shifting on the repair stand a little annoying. And what happens if you throw a chain? Okay, I guess that's three things. But Di2 is already there with the programmability and demonstrated ability to hack into unforeseen functionality. It's pretty usual for SRAM road to be focused primarily on quote-unquote normal users in the performance-oriented market.
