The release of Eagle 12-speed saw the widest gear range and arguably the best mechanical shifting of any single-ring drivetrain on the market. Price was a hurdle at first, but now Eagle technology has trickled all the way down to the NX level, making the substantial benefits available to more riders than ever. This NX Eagle DUB Crankset is made of 6000-series aluminum for durability, and uses SRAM's X-Sync 2 chainring for quiet operation, unwavering chain retention, and smooth shifting. This is the non-Boost version, with a 6mm offset chainring for bikes with QR or 12 x 142mm rear hub spacing. It uses SRAM's new DUB spindle, delivering better stiffness than GXP and a lower weight than BB30, and is compatible with almost any frame if you get the correct DUB bottom bracket.
