Looks really promising especially for those who need the range of a triple since this will be a great way to get the gear combos without the hassle. I've been using Rival for almost a year now and really like that gruppo, so when it's time to upgrade I'll definitely get Red. Next bike will be SRAM equipped as well, and not because I hate Shimano but I like SRAM's shifter ergonomics and adjustability, lower weight, and cheaper price.
