Boost frames feature a wider, generally 148mm rear hub, and require a wider chainline from the center of the frameset. For Boost this is 52mm. If you are building out a Boost frame and want to run SRAM's NX Eagle 12-speed system, this is the crankset you need. You will also need to get the correct DUB bottom bracket cups for your frame standard. NX Eagle delivers improbable value, performance and efficiency for mountain bikers looking to embrace the SRAM Eagle 1x12 revolution. The NX series may make some compromises in materials and weight, but the performance technology that drives all Eagle equipment levels. The SRAM NX Eagle DUB Boost Crankset is a great example, as it features the DUB bottom bracket and crank spindle standard, Direct Mount X-Sync 2 Chainring engineering, and 6000 series forged aluminum arms.

The DUB standard is a 28.99mm crank spindle diameter based system that allows SRAM to use a single standard for any bottom bracket shell. The frame dictates the cup style, which is the only variable SRAM must offer options for. The rider can still take advantage of the oversized spindle and lighter weight close to the 30mm diameter of BB30, but with virtually any current or likely future bottom bracket option.

The NX Eagle DUB Boost Crankset is only available with the Direct Mount chainring system, and is sold here as a complete crankset with a 3mm offset chainring. In this case the Eagle DM chainring is a stamped steel model, for a frameset with a 52mm Boost chainline. The X-Sync 2 chainring tooth profile improves on the original version, with better chain engagement, superior mud shedding and wear with the wide range and extreme angles of the 1x12 mountain drivetrain.

As part of an very affordable, innovative mountain drivetrain the NX Eagle DUB Crankset is the central component of propulsion, channeling your input through the chain and to the rear hub propelling you along the trail of the day. Have fun!
