SRAM's Eagle technology has revolutionized the way mountain bikers ride. It has provided an ultra-wide gear range, 12-speeds, and the simplicity of a 1x drivetrain. The SRAM NX Eagle Dub Groupset provides all you need to make the jump to a 1x12 drivetrain. It comes with a SRAM NX Eagle rear derailleur, trigger shifter with a clamp, a SRAM NX Eagle Dub crankset with a 32t X-Sync chainring, a 126 link 12-speed chain, an XG-1230 11-50t cassette, and a chain gap gauge. The only thing you would need to use this groupset is a SRAM Dub bottom bracket to fit your bike's bottom bracket. With this groupset, you'll have no issues riding on every terrain.
