After its first release we could already hear the groans of the riders accustomed to the ever-changing standards in the mountain biking world. But before you go just listen to us. Focusing first on bearing durability and sealing and then designing the spindle diameter to meet those needs SRAM was able to develop a new crankset which is no less light and tough than systems with 30 mm spindles but provides increased system durability with 24mm spindles. It's a really simple concept which takes SRAM Eagle DUB cranks to the top of the market thanks to the optimal combination of lightness efficiency hard pedaling and reliability in all twelve gears.
