Description

The SRAM XX SL Eagle Transmission (T-Type) Cassette is a major reason why Eagle Transmission offers the best-ever inboard and outboard shifting performance under load. Thanks to its full X-Sync design, the harder you pedal, the better it shifts. Literally. Our lightest Eagle cassette in history lasts far longer and delivers more precision. Its new-gen design is fully machined, hardened steel X-Dome architecture for gears 4-12 and an ultra-lightweight, all-aluminum Spider Cog for gears 1-3. Engineered as integrated and interdependent transmission components, the XX Eagle Transmission Cassette and derailleur contact directly, ensuring perfect alignment on every bike. From its massive 520% gear range, the 52 tooth cog steps down with improved gear progression with 44 and 38 tooth cogs in the low end (compared to the Eagle drivetrain 10-52-tooth cassette). Featuring a clearly marked Setup Cog, install is both simple and fool-proof.

This cassette is not suitable for E-MTB.
