This is Sram's NX Eagle™ Groupset. The NX Eagle groupset brings the performance from the top of the line XX1 Eagle groupset to a bigger variety of riders. This complete groupset includes; trigger shifter, rear derailleur, crankset, cassette, and chain.
NX Eagle Trigger Shifter:
The NX Eagle Trigger Shifter features ZeroLoss technology which means when you press the lever to shift, the cable is instantly engaged. Another feature of the NX Eagle Trigger Shifter is its X-Actuation™. X-Actuation retains the shifters sharp and precise shifting across the whole cassette. Sram's MatchMaker™ X Integrated mounting system allows you to mount this shifter on Sram brake levers.

NX Eagle Rear Derailleur:
This Sram NX Rear Derailleur features the X-Horizon™ 1x-specific design with the X-Sync™ 14-tooth lower pulley wheel to help make the smooth shifting and pedaling feel that the Eagle line is known for.

NX Eagle Crankset:
The NX Eagle Crankset features the X-Sync™2 chainring, which are designed to help with chain retention to make pedaling more smooth and efficient. The X-Sync2 design also helps increase the life of the chainring by reducing friction and wear. The crankset uses DUB™ bottom bracket technology. The DUB technology delivers a better, more consistent fit between the bottom bracket spindle and bearings. The better fit creates a better seal, so the trail stays out of your bottom bracket.
The NX Eagle PG-1230 Cassette offers the climbing ratios and performance that the Eagle line is known for, but with the advantages of using a splined-drive body. The first 8 cogs of the cassette are made of lightweight stamped steel, while the 4 biggest cogs are made of high-strength steel with an aluminum spider. The cassette also features PowerGlide II technology which means the cassette is designed for off-road use. The cassette is durable, reliable, and the optimized tooth profile delivers positive and quick shifting. The cassette is even strong enough to reach the durability needs of E-MTBs.
The NX Eagle Chain uses Sram's Flow Link™ technology which reduces friction and noise thanks to its ultra-smooth chain inner-plates. The chain features the PowerLock® link, which is a tool-free way to connect the chain together.
