Strength is how the X01 Eagle DUB crankset takes capability to places never before reached. It’s the strongest crank in the entire Eagle ecosystem, and it holds this status at a weight that is hard to fathom. Featuring industry-proven and rider-beloved DUB technology to radically simplify the relationship of spindle to bottom bracket, delivering unprecedented simplicity, compatibility and durability. The X01 Eagle DUB Crankset also comes with our Eagle Colorsystem, in the X01 master colorway - to go perfect with all other available cassette and chain colors – from Black to Gold to Rainbow, and now Copper. With a raw aluminum finish on the X-SYNC 2 chainring teeth – to keep looking fresh throughout its long lifespan. X-Sync 2SRAM X-Sync 2 Eagle is the next evolution of SRAM X-Sync technology. The aggressiv teeth design provides better chain retention for a smoother, more efficient pedal feel. With a focus on long wear-life, the X-Sync 2 Eagle design reduces friction and the accumulation of mud, grit and grime. DUB technologyThe unit consisting of crankshaft and bottom bracket is the heart of the DUB technology. Here stiffness meets durability. SRAM has gone a step further and made everything even easier and better. It's the system approach through the integration of chainring, crank, shaft and bottom bracket that means better drive performance.
