The GX Eagle 12sp DUB Boost Groupset offers you the same gearing range and technologies as seen on SRAM’s XX1 and X01 Eagle DUB models, but at a price that puts it within the reach of the masses! It’s designed to help you realize your bike's true potential and has been designed, tested and proven to deliver lightweight, durable and reliable performance on all trail types.

The chainset adopts SRAM’s revised and updated “DUB” bottom bracket system, which provides improved integration between the crank, spindle and bottom bracket. This particular groupset is also specifically designed for “Boost” Type frames so the chainset has a wider chainline, ensuring clearance with these frame's wider rear ends.

It has been fine tuned to deliver consistent performance every time you are out on the bike. GX Eagle DUB also provides outstanding power transfer and durability due to the highly advanced DUB bottom bracket system. Plus with X-Sync 2 chainring with its carefully engineered tooth profile, you’ll enjoy exceptional chain control and pedalling performance.
