When SRAM first released the Eagle 12-speed group, it took all of the good things about 1×11 drivetrains and took it up a step. Improved chain retention, less maintenance, simpler shifting, and quieter operation all improved the ride experience but with the addition of the 12th cog, the gear range used to be brought to the level of a 2x setup without the troublesome mis-shifts of a front derailleur. NX Eagle is the most recent expansion to the Eagle ecosystem and lowers the barrier to entry by having the lowest cost yet for an Eagle drivetrain. The NX Eagle DUB Groupset includes all of the necessary components for a 1×12 upgrade, excluding a bottom bracket. This groupset includes the crankset, cassette, chain, rear derailleur, shifter, and b-gap adjustment tool. The crankset comes with a 32t, 6mm offset chainring for non-Boost bikes with QR or 12 x 142mm rear hub spacing. It uses SRAM’s DUB spindle, with a view to work with any frame so long as you get the right kind DUB bottom bracket (not included). The derailleur and shifter perform comparably to the top-tier Eagle groups, but there’s a difference in weight and the materials comprising the shift levers. The cassette’s range is 11-50t, so you still get the bailout gear that make’s Eagle so pleasant, but with one less tooth at the small cog in comparison to the other Eagle cassettes. This allows the cassette to work with normal freehubs, no need for an XD driver.
