Strong and lightweight to cope with the demands of rigorous riding, this Eagle DUB chainset is designed to be durable and stiff, with every part of the crankset working together to ensure efficient and effective performance with every rotation. Utilising the aggressively toothed X-Sync 2 chainring, the aluminium-built spider keeps a superb hold on your chain and provides a smooth feel as you propel yourself to greatness.  The 7000 series aluminium crank arms allow for explosive power transfer as you rise uphill and sprint along the straight, with the wider BOOST design chainline allowing you to make the most of your larger frame and tyres to push your off-road rides to the very limit.  Technologies X-Sync 2: X-Sync 2 Eagle is the next evolution of SRAM X-Sync technology. The aggressive tooth design provides better chain retention for a smoother, more efficient pedal feel. With a focus on long wear-life, the X-Sync Eagle design reduces friction and the accumulation of mud, grit and grime. DUB Technology: The relationship between bottom bracket spindle and bearing is the core of DUB™ technology. It’s where stiffness meets durability. SRAM took it a step beyond conventional thinking and made everything simpler, by better integrating the relationship between chainring, crank, spindle and bottom bracket. It’s this clear system approach that equals better drivetrain performance.
