卡式飛輪 - SRAM CASSETTE XG-1299 10-50T
The X-DOME™ Eagle™ cassette has no peer. It buried the last dangling shred of an argument in favor of a mountain bike front derailleur. And now, it’s 10-50 tooth gear range has open the door for an entire ecosystem of Eagle™ groupsets. Designed for use with our 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 the strongest cassette on the market. New shifting characteristics improve both inboard and outboard shifting, as well as chain retention. This cassette matches up perfectly in performance and color to XX1 Eagle AXS™ enabled componentry.

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.
The revolutionary machined design of the X-DOME" cassette uses the same grueling manufacturing techniques that produced the PowerDome" road cassette. With X-DOME⁻", nine of the cogs are CNC machined together out of a single block of billet steel, creating an incredibly lightweight, precise and strong cassette.
Eagle™ tech no logy represents our newest 1x drivetrain technology. Eagle™ is a lighter, simpler, more durable, and easier to use drivetrain. Eagle™ features all-new 1x comp orients, en gineered for eve n greater durability and performance while maintaining a significant weight advantage over other drivetrain solutions. Eagle™ technology also provides an expanded gear range of 500%, which is equal to 2x11 drivetrains.
X-GLIDER2 is next generation of SRAM X-GLIDE_U technology optimized for the EAGLE" 12-speed cassette. It provides quick, precise, power-on shifting performanee throughout the gear range, and increases chain retention on larger cogs.
