1299 XXSL T Type Eagle 10 52 12 speed Cassette

The 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.Key Features:New-gen design is our lightest ever 10-52T cassette due to the ultra-lightweight, all-aluminum Spider CogFull X-SYNC for best-ever inboard and outboard shifting performanceunder load Optimized gear steps on low end55mm chainline compatibility for more moderate chain angle, longer wear and greater precision Setup Cog for fool-proof set upUtilizes well accepted and broadly available XD driverbody
