SRAM XX1 1x11 Discussion

But the SRAM advantage is having the greater range of the 10-42 cassette which Shimano does not give you.

Which chainring did you select (28T -> 38T)?
Do you have several of them?

The standard 32T works fine for me.

Thanks. When ordering parts few weeks ago, I used an online gear ratio calculations to compare with my current Shimano M970.
http://www.gear-calculator.com/#KB=28&RZ=10,12,14,16,18,21,24,28,32,36,42&GR=DERS&KB2=22,32,44&RZ2=11,12,14,16,18,21,24,28,32&GT2=DERS&UF2=2160&TF=85&UF=2295&SL=2

The not very brave 28T came at the same ratio for the low speed, while loosing the 3 top speeds.
Being unsure I took that one to try first. I'll see mounted how it goes.
