The SRAM PG-1210 Eagle cassette represents the ideal entry point into the Eagle ecosystem for all mountain bikers seeking performance, durability and universal compatibility. With its 11-50 tooth, 12-speed range, it offers an exceptional 454% spread that allows you to tackle steep climbs and fast descents without ever missing the right gear. Designed to fit standard 8/9/10-speed HG freehub bodies, it eliminates the need for an XD driver and installs on the majority of wheels on the market.

Technical Highlights

• PowerGlide II Technology: Optimized tooth profile and shift ramps for fast, precise and reliable shifting off-road, even under high load.
• Replaceable E-MTB cogs: The first three cogs (11-13-15 teeth) are individually replaceable, extending the cassette's lifespan without complete replacement — ideal for E-MTBs and intensive use.
• Wide compatibility: Compatible with all SRAM Eagle 12-speed derailleurs (SX, NX, GX, X01, XX1, S-Series) and Eagle chains. Not compatible with SRAM Transmission T-Type.
• Robust construction: All cogs in hardened steel offering excellent wear resistance, black finish for a discreet and modern aesthetic.

Range and Progression

The PG-1210 cassette offers a 11-13-15-17-19-22-25-28-32-36-42-50 tooth range, providing harmonious progression across the entire spectrum. The 50-tooth large cog provides ultra-low gearing for technical climbs and steep terrain, while the 11-tooth small cog ensures comfortable top speed on flats and descents. This 454% range equals that of a classic 2x11 drivetrain, while maintaining the simplicity and reliability of a 1x single-chainring configuration.

Compatibility and Installation

The PG-1210 mounts on standard HG (Hyperglide) freehub bodies used by Shimano/SRAM 8, 9 and 10-speed hubs. It installs directly without spacer on HG M hubs (MTB 7-10 speed, MTB 11-speed), and with a 1.85 mm spacer on HG L hubs. This universal compatibility makes it accessible to all setups, including entry-level and mid-range wheels, without requiring investment in an XD Driver body.

Uses and Applications

• All-Mountain and Enduro MTB: Ideal range for linking steep climbs and fast descents on mixed terrain.
• E-MTB: E-MTB homologation and replaceable cogs designed to withstand high torque and accelerated wear of E-MTBs.
• Cross-Country and Bikepacking: Wide range allowing optimal cadence on varied terrain, ideal for long rides and bike touring.
• Budget-friendly upgrade: Affordable solution to upgrade to 12-speed Eagle without changing wheels or hub.

Maintenance and Durability

The rebuildable design of the PG-1210 is a major asset: the first three cogs (11-13-15 teeth), subject to the most wear ("speed limit gears"), can be replaced separately. This modularity reduces long-term maintenance costs and limits waste. Regular cleaning, proper chain lubrication and periodic wear inspection ensure lasting performance.
