Now that the triple seems all but dead in the mid to high range groups what is everyone using?
During 2020 I built up a bike with a SRAM Eagle 10-50T twelve-speed cassette on garden-variety Shimano XT disc hubs driven by a 40T thick-thin single chainwheel. SRAM Eagle GX rear (one and only) derailleur. Shifting on the drop bar is handled by a Microshift BR-SR-M12 indexed bar end. The 1x12 well-spaced indexed ratios go from a 21 g.i. low to a 104 g.i. high.
I've been assured that this 1x12 gear range is ridiculously inadequate for touring. The Trek 520 is triple geared 20-108 g.i. The Surly Disc Trucker is triple geared 21-110 g.i. So, you know, whatever.
