About SRAM NX Eagle PG-1230 12-speed cassette
The SRAM NX Eagle PG-1230 cassette provides a wide 11‑50T gear range across twelve speeds, delivering low‑cadence climbing power and high‑speed efficiency. Each of the twelve sprockets is made from steel and riveted to an aluminum spider, offering durability for heavy‑duty use and the high loads typical of e‑MTB applications. Gear steps are optimized across the entire range, ensuring smooth transitions whether on steep ascents or fast descents. The cassette is designed for splined freehub bodies and is compatible with Shimano 8‑, 9‑, and 10‑speed cassette bodies, allowing straightforward upgrades within the SRAM Eagle drivetrain ecosystem. Its construction meets SRAM’s durability standards for off‑road and e‑bike riding, making it a reliable choice for cross‑country, trail, all‑mountain, and enduro disciplines. Recommended pairing is with an SRAM Eagle chain, and the cassette ships as a single unit without additional packaging.
