We do that with the 2x11. Our everyday gearing iis 52/36 and 11/25., which is fine for us for moderate climbing.


We have an 11-36 for the back , but rarely use it.


Looking at the gear steps, the Eagle setup can cover the same range as the 11-36 setup, and the jumps are bigger but not all that bad..


I have 1x11 on my MTB. I think its more of an advantage on an MTB given that you don't have to worry about making a front shift under load on rough terrain when sudden changes in a single track trail present themselves. Even then, I'm not totally sold on 1x11 for a MTB. My current MTB gearing I need more top end, which would require a large chain ring, but then I'd have to also put on a larger rear cassette yo keep the low end where I need it. The new systems with 10 tooth small cogs help in that regard.


To me, the bigger issues with 1x are the weight of the huge rear cassettes ( my assumption is a total 1x system can actually be heavier than a 2x); the aesthetics of an insanely large rear cassette, the wear of the big cogs if you make them out of Ti to save weight, the inefficiency of the small 10 tooth cog.


I haven't ridden my 1x enough yet to really come to a conclusion how well I like it, and whether any of the above is an issue in practice.
