SRAM XX SL Eagle Transmission Cassette (XS-1299)

The XX SL Eagle Transmission (T-Type) Cassette is the key to achieving the best-ever inboard and outboard shifting performance under load with Eagle Transmission. Its complete X-Sync design ensures that the harder you pedal, the better it shifts, resulting in unrivaled precision.

This is SRAM's lightest Eagle cassette to date, and it is built to last and provide maximum efficiency. The new-gen design is fully machined, with hardened steel X-Dome architecture for gears 4-12 and an ultralightweight, all-aluminum Spider Cog for gears 1-3.

Designed to work in conjunction with the XX Eagle Transmission Derailleur, the cassette, and derailleur are engineered as integrated and interdependent transmission components that make direct contact, ensuring perfect alignment on every bike. With a massive 520% gear range, the 52-tooth cog steps down with improved gear progression with 44 and 38-tooth cogs in the low end, outperforming the Eagle drivetrain's 10-52-tooth cassette. The Setup Cog is clearly marked, making installation simple and foolproof. Experience the ultimate shifting performance with the XX SL Eagle Transmission (T-Type) Cassette.
