SRAM Eagle XS‑1275 T‑Type Transmission 10‑52 Cassette - 12 Speed

BETTER SHIFTING. SMOOTH GEARING

The GX Eagle Transmission (T-Type) cassette delivers smooth, precise shifting—even under heavy pedaling. Its full X-SYNC™ design and 520% range provide better gear steps, while the 55mm chainline improves chain alignment and precision. The marked Setup Cog makes installation quick and easy, with a durable Pindome design for gears 1–8 and a single-piece mini-cluster for gears 9–12.

• X-SYNC for best-ever inboard and outboard shifting performance under load
• 520% range with optimized gear steps on low end
• 55mm chainline compatibility for more moderate chain angle, longer wear, and greater precision
