Sram NX Eagle Boost 148 DUB crank DM X-SYNC 32 teeth 12-speed

The SRAM NX crank features an Eagle design and known performance, making it the latest addition to the Eagle Ecosystem. With SRAM X-SYNC-2 chainrings, the NX crank ensures optimal chain control. Each individual tooth has been precisely designed and manufactured for shape and strength, providing efficient, safe, and silent operation with SRAM chain links. DUB technology introduces an advanced bottom bracket and a completely new crank axle design, resulting in a unified approach to bottom bracket shell standards, better sealing against contamination, and full forward and backward compatibility. DUB sets a new benchmark in performance and durability.

X-SYNC 2 is the latest development of SRAM X-SYNC technology. The tooth profile of the chainring increases chain tension and efficiency while pedaling. The lifespan of the chainring is extended due to X-SYNC EAGLE technology, which reduces friction and dirt.

DUB represents the integration of crankshaft and bottom bracket, where stiffness meets durability. SRAM has simplified the design by better integrating the chainring, crank, shaft, and bottom bracket, leading to improved drive performance.
