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.
How do you run an Eagle 10-50 on a “garden variety Shimano” hub? I thought the 10 tooth cog needed an SRAM XD freehub. A “garden variety Shimano” hub shouldn’t take anything lower than a 11. I really do what to know how you do it.
