卡式飛輪  -  Sram XG-1299 Eagle Cassette 10-50T
CS-XG-1299-A2

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.

X-DOME
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
Eagle 技術代表了我們最新的 1x 傳動系統技術。 Eagle 是一款更輕、更簡易、更耐用且更易於使用的傳動系統。 Eagle 具有全新的 1x 組件，具更高耐用性和性能，同時在重量上比其他動力傳動系統更具優勢。 Eagle 技術還提供了 500％ 的齒比範圍讓爬坡變得更加從容不迫，相當於 2x11 傳動系統。

X-GLIDE 2
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.
