This high-quality 12 speed cassette is part of the renowned Eagle series and it's lighter, simpler, tougher as well as easier to use. Engineered for increased strength, while keeping its weight to a minimum, it's also a great choice of upgrade for riders who want to enjoy smoother, quieter shifting operation on their trail adventures. MTB Cassette with X-Dome Technology The X-Dome Eagle cassette has no peer. It buried the last dangling shred of an argument in favour of a mountain bike front derailleur. And now, its 10-50 tooth gear range has opened the door for an entire ecosystem of Eagle groupsets. Designed for use with SRAM's proven, reliable XD driver body, this 12 speed, cassette offers an optimal 500-percent gear range. In independent tests the X-Dome architecture is proven to yield one of the strongest cassettes on the market. Updated shifting characteristics improve both inboard and outboard shifting, as well as chain retention. This cassette matches up perfectly in performance and colour to XX1 Eagle AXS enabled componentry. Technologies: X-Dome: X-Dome technology creates an incredibly lightweight, precise and strong cassette. The open design aids in mud clearance, giving you cleaner shifting performance and longer component life. Eagle: Eagle technology represents updated 1x drivetrain technology. Eagle is a lighter, simpler, more durable, and easier to use drivetrain. Eagle features revised 1x components, engineered for even greater durability and performance while maintaining a significant weight advantage over other drivetrain solutions. Eagle technology also provides an expanded gear range of 520%, which is equal to 2x11 drivetrains. X-Glide 2: X-Glide 2 is next generation of SRAM X-Glide technology optimised for the Eagle 12-speed cassette. It provides quick, precise, power-on shifting performance throughout the gear range, and increases chain retention on larger cogs. XD Driver Body: XD is a cassette driver body design that allows the use of a 10-tooth small cog and provides an improved interface with the cassette. Rainbow Colourway: Is perfectly matched to work with XX1 Eagle AXS. Updated shifting features create a smoother, quieter system with enhanced inboard and outboard shift performance. XD driver body compatible. Manufacturer's Part Number: 00.2418.098.000
