The NX Eagle DUB 12 Speed Boost Groupset offers the same features, technologies and gear range as seen on SRAM’S top-end XX1 and X01 Eagle drivetrains. However, the difference with NX Eagle is that it falls within the reach of more rider’s budgets. It also adopts SRAM’s revised and updated bottom bracket system called “DUB”, which provides improved integration between the crank, spindle and bottom bracket. This particular groupset is specifically designed for "Boost" Type frames so the chainset has a wider chainline, ensuring clearance with these frame's wider rear ends.

Chainset - The NX Eagle DUB Boost chainset is engineered to deliver Eagle 12 speed performance and styling that everyone can enjoy. In addition to the excellent chain retention that’s provided by the X-SYNC™2 chainrings, this chainset provides outstanding power transfer and durability due to the highly advanced DUB bottom bracket system.
