The SRAM NX crankset combines the style and performance of the Eagle ecosystem. Designed for X-SYNC 2 chainrings from SRAM, the NX crankset is designed for total chain control; each tooth profile is precisely engineered to work quietly, efficiently and safely with the internal and external links of the Eagle chain. DUB technology features a redesigned bottom bracket and a new axle design that together offer a more uniform approach to bottom bracket mounting, improved sealing and compatibility with the vast majority of frames. So everyone can enjoy a new measure of strength and performance.Details:6000 series forged aluminum cranksDUB technology offers a uniform approach to bottom bracket mounting, improved sealing and compatibility with the vast majority of framesSteel chainringChainring: 32 tooth BoostSpeeds: 12DUB axleCompatible with bottom bracket: DUB BSA73,DUB PF89.5,DUB PF92,DUB PF30 MTB73,DUB BB30 MTB73Chain line: 52.0 mmCrank length 175 Material Aluminum Number of ch...
