SRAM GX Eagle DUB Lunar Groupset

Featuring much of the same technology as their highest-end groupsets, the SRAM GX Eagle Boost DUB Lunar Groupset delivers a premium drivetrain experience in a durable, aluminium package. As the benchmark for trail performance, this groupset sees a 10-52t cassette to supply a phenomenal 520% gear range - perfect for steep, technical climbing and the descents that come with them. An ideal choice for any mountain bike build, the GX groupset is commonplace amongst a range of disciplines, from lightweight cross-country builds to burly enduro sleds. 

The GX Eagle DUB crankset is the highest-end aluminium crankset that SRAM produces. Built strong to pair well with modern low, slack and long geometry, its durable aluminium build ensures pedal strikes are a worry of the past. The DUB standard resists ingress from dirt and water, and the aggressive profile of the X-SYNC 2 chainring supplies supreme chain retention and near-silent running. Compatible with the industry-recognised XD freehub standard, the XG-1275 is suitable for a range of wheelsets and is lightweight in its design to reduce unsprung weight. 

Full-featured and versatile, the GX Eagle derailleur and shifter combination sees razor-sharp shifting across the entire 12-speed range. With a tactile feel that mirrors that of more expensive models in the SRAM ecosystem, the shifter offers a positive, direct feel with every engagement. Complete with a roller-clutch and convenient locking mechanism, the derailleur reduces chain-slap for a quiet ride on rough terrain and offers simple wheel removal.
