SRAM GX Eagle DUB Lunar Boost Groupset

With crisp shifting performance and a durable aluminium construction, the SRAM GX Eagle DUB Lunar Boost Groupset delivers confidence-inspiring reliability and is suitable for a wide range of mountain bike applications. From harsh enduro races to slick cross-country climbs, this groupset is renowned for its exceptional performance, ensuring it is a prime choice for any discerning cyclist. Featuring an exceptionally wide 520% gear range this groupset aids performance across all gradients, providing you with the gearing you need to perform at your best. 

As the highest-end SRAM aluminium crankset available, the GX Eagle arms see a premium finish and a durable design that is built to last. The DUB standard is compatible with any DUB bottom bracket and has enhanced weather sealing to reduce ingress from water and dirt. The X-SYNC 2 Boost chainring features aggressively designed teeth, which offer improved chain retention and reduced noise over traditional configurations, as well as a longer lifespan. The XG-1275 groupset channels technology from the highest end SRAM models, and is compatible with the industry-recognised XD freehub standard.

The GX shifter has a positive, tactile feel that oozes quality with every engagement. Paired with the sleek GX rear derailleur it provides smooth and precise shifting, offering performance reminiscent of SRAM’s flagship groupsets. A roller bearing clutch mechanism prevents unwanted chain-slap for a near-silent ride even on loose terrain, and the locking mechanism sees easy wheel removal when required.
