At this point, you’ve likely “made the leap,” to swipe SRAM’s marketing parlance. Whether you modified a 10-speed cassette with a One-Up-style expansion cog, or adopted early and wore out your first cassette, the SRAM XX1 X-DOME Cassette is the pinnacle of one-by technology. By trading freehub bodies for drivers, SRAM was able to put a tiny, 10-tooth cog on the end to balance out the monster, 42-tooth cog on the low end. This ensures that the balance of granny grinding to flat-out-flying is maintained.
