I will never go back to a triple gearing system ever again. I just switched my hybrid from a 3x9 to a 1x11 system a few months ago. I use it mainly on rails to trails, canal trails and so forth. I don't go fast with it or do any overly steep climbing. Having a 11-42 11 speed in rear and 36 chainring has been great for my riding on this bike.

My two mountain bikes...yea...won't ever switch away from a 1x system. So much easier to quickly shift and not have to work about two derailleurs to get to an optimal gear.

But for a Diverge, I can see wanting a 2x system to get the speed when the rider is on a road and yet able to drop down to the smaller chainring on steep hills.
