evo.com | SRAM Groupset > Cue that high pitched bird that's at the start of all those nature scenes: 12 speeds! SRAM's Eagle technology has finally made it to their NX level, meaning you don't have to be a dentist to own the current state of the art. Shifter, crankset, cassette, chain, and rear D: all designed together to work as a complete system. Just grab a DUB bottom bracket and your bike is ready for all-mountain domination. From XC to enduro racing, Eagle has proven itself a simple and reliable drivetrain for all riders, letting you shift quickly through a wide range of gears. With a 32t chainring and 11-50t out back, your bike is ready for any terrain. The SRAM NX Eagle DUB Boost Groupset is for bikes with Boost spacing. PowerGlide II Cassette technology optimized for offroad. More reliable. More durable. Better performing, thanks to an optimal tooth profile and shift ramp design for quick and positive index shifting. Go climb a mountain. Flow Link Ultra-smooth chain inner-plates are completely devoid of square edges, resulting in a chain that engages the cassette and chainring with far less friction, for quieter performance and better wear life. The design allows a narrower overall profile that can withstand greater angles, and also allows for a flatter outer-plate, which means more consistent chain riveting and enhanced overall strength. DUB(TM) Technology Compatible with all existing BB sizes and frames. X-Actuation(TM) Developed specifically for SRAM 1x(TM), X-Actuation(TM) keeps shifting sharp and consistent across the entire cassette. Cage Lock(TM) With Cage Lock(TM) technology in the rear derailleur, wheel removal and installation-as well as chain installation-becomes faster and simpler. Just push the cage forward to create slack and lock it into place. | SRAM NX Eagle DUB Boost Groupset 2023 - 175mm Cranks
