Sram has hit a home run with the Force 1 and Rival 1 groupsets, as far as I can tell. The simplicity of the system is entirely logical and I applaud Sram for its initiative.
Having 11-speeds frees the rider to enjoy riding more; no dropped chains, reduced chain slap, and stupid-simple gear choice.
It's not a "run out and buy" sort of development for me but I'll definitely be putting Sram Force 1 and Rival 1 on my short list for my next bike purchase or build.
