I agree, that is a very nice change. My 2013 Domane Trek road bike is a standard Shimano 105 compact 50/34 up front, but a not too bad 12-30 in back. Gets me by for our hills, up here, but just. If I'm running out of gas, so to speak, or fighting a stiff headwind to get up one of my "special" hills (they all have names, now ), I find myself wishing for one or, even better, two more gears to help.

Speaking of advertised specs being off, my new Salsa Warbird was advertised as having a 46/36 up front, but when I looked, it was actually a 34 on the small ring. Had planned on changing it to an even smaller ring, but instead went from an 11-30 in the back to an XT 11-32. Still very close to the Domane at the low end, 34 and 30 versus 34 and 32, but even that one extra gear makes a difference.
