When Eagle was first released, the price was a considerable barrier. Over the last few years that has changed, with Eagle technology trickling all the way down to the NX level, making the substantial benefits of the 12-speed groupset available at the lowest price point to date. The NX Eagle DUB Crankset is constructed from 6000-series aluminum for durability. It uses SRAM's X-Sync 2 chainrings for quiet operation, smooth shifting, and infallible chain retention. This version comes with a 3mm offset chainring for 12 x 148mm Boost spacing. It has a DUB spindle that delivers better stiffness than GXP and a lower weight than BB30, and is compatible with virtually any frame if you get the correct DUB bottom bracket.
