Experience the best-ever inboard and outboard shifting performance under load with the X0 Eagle Transmission (T-Type) Cassette. As an integrated and interdependent component of the Eagle Transmission system, this cassette and derailleur contact directly, ensuring perfect alignment on every compatible bike. The X0 Transmission Cassette comes cloaked in an eye-catching Dark Polar finish and with electroless nickel plating that provides incredible resistance to corrosion and wear. The full X-Sync design is the secret sauce that ensures smooth shifts even under heavy pedaling. The 52-tooth cog steps down with improved gear progression with 44 and 38-tooth cogs in the low end, offering a massive 520% gear range compared to the Eagle drivetrain 10-52-tooth cassette. With full approval for E-MTB use, this cassette is built for a 55mm chainline, delivering increased durability and precision with milder chain angles throughout the full range, low to high. Plus, the clearly marked Setup Cog makes installation simple and foolproof. Full X-SYNC for best-ever inboard and outboard shifting performance under load Optimized gear steps on the low end 55mm chainline compatibility for a more moderate chain angle, longer wear, and greater precision Setup Cog for foolproof setup Features X-DOME with a lighter aluminum 12th gear Fully E-MTB approved Details: Model: CS-XS-1295-A1 Gear Range: 10-52t Cog Sizes 10-52t: N/A Freehub Interface: SRAM XD Material: Steel Weight: 380 grams SRAM EAGLE TRANSMISSION AXS COMPATIBILITY: The SRAM X0 Eagle Transmission Cassette is compatible with the following: Frameset: Any frame that fulfills the “UDH Specification” featuring a hanger-less interface can be upgraded.
