When SRAM first released the Eagle 12-speed group, it took all 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 was brought to the level of a 2x setup without the troublesome mis-shifts of a front derailleur. NX Eagle is the newest 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 the necessary components for a 1×12 upgrade, with the exception of 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, which will work with any frame as long as you get the correct DUB bottom bracket (not included). The derailleur and shifter perform comparably to the top-tier Eagle groups, but there is 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 on the small cog compared to the other Eagle cassettes. This allows the cassette to work with normal freehubs, no need for an XD driver.

When SRAM initially launched the Eagle 12-speed group, we were absolutely blown away by its massive 500% gear range–the same you’d find with many 2x drivetrains–all without dealing with the added weight or annoying miss-shifts of a pesky front derailleur. The catch was its astoundingly high price, which relegated this fancy drivetrain to the likes of magazine testers and premium builds from the leading bike manufacturers, but left us regular trail riders to sit aside and wait for a budget-friendly option to emerge. Seeing the need for an affordable entry into Eagle’s numerous benefits in gear range and 1x shifting efficiency, SRAM created the GX Eagle 12-Speed GXP Groupset for the needs of dedicated riders saving every last dollar for a reliable and efficient 1×12 groupset for their trusty trail bike. The GX Eagle 12-Speed GXP Groupset contains everything you’ll need, besides a GXP bottom bracket and an XD driver body, to hook up your trail rig with a crisp-shifting drivetrain across the widest range of usable gears possible on a 1x setup. This specific group is specifically tailored to non-Boost axle spacing with the included direct-mount crankset featuring a 49-millimeter chainline, as well as accommodating GXP bottom brackets with the 22/24-millimeter stepped GXP spindle. This GX Eagle 12-speed Direct-Mount Crankset is made from 7000-series aluminum for high levels of strength without blowing the bank on fancier carbon construction. The plate-sized XG-1275 Cassette steals the show with its unbelievable gear range helping you power up steep climbs without ever wishing for a front derailleur or seeking out just one more gear. This cassette uses stamped steel cogs placed together with stainless steel pins, with the 50-tooth cog retaining its aluminum construction for weight savings. This construction technique makes it possible to keep overall costs down while retaining a durable cassette that shifts beautifully across its 10 to 50-tooth range. This cheaper pri…
