CX is not very popular around my area, but I see the trend of XC racers going to 1x10 setup with Raceface rings a lot. The only concern to me was that when the chain is on the biggest or smallest cog at the back, I can feel the chain grinding against the chainring. I wonder how that will affect the overall longevity of the chain and chainring. And also loosing gear range also means you might have to dismount when you can ride over.
I'm waiting for the new 2015 XTR 11sp. I wish the mechanical version is compatible with road shifters so that I can run 11-36T with the clutch derailleur. If that can be done, I'm down for 1x11 setup.
