The NX cassette gives riders every bit of the climbing range that the Eagle ecosystem affords with a simple upgrade to splined-drive body wheels. The PG-1230 is the only Eagle cassette designed to be durable enough to withstand the increased demands of E-MTB applications and a perfect solution to heavy-duty use and abuse. Eagle technology provides an expanded, optimum gear range making you fast on the flats, giving you control on the climbs and unleashing your speed on the descents. Eagle is a complete drivetrain system that was developed to be an integrated high-performance ecosystem. The engineering and testing that went into the development provide for maximum performance, safety, and long-term durability to ensure a great consumer ride experience. SRAM guarantees this performance when Eagle drivetrains are used as a complete ecosystem.
