卡式飛輪 - SRAM RED XG-1290 CASSETTE
SRAM RED XG-1290 飛輪是我們突破性的 Deep Range™ 寬齒比技術中不可或缺的一部分。每個飛輪都配備了 10T 的檔位，且專為無線電變設計，提升了變速表現。
．齒間更加平滑的傳動比變化 - 至少提供 5 個單齒變化 - 同時提供了更寬的齒比範圍
．需與 XDR™ 棘輪座配合使用
．一體切削的鋼製 X-Dome™ 設計降低了重量
．所有 2016 年後的 ZIPP 的輪組均可更換 XDR™ 棘輪座

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 in the credibly lightweight, precise and strong cassette.
The XDR™ driver body is a universal mounting system for cassettes that incorporate cogs with fewer than 11 teeth. It allows for lighter and more versatile drivetrains without requiring new rear axle standards, cassette tools or hub redesigns. The XDR™ interface is 1.85mm longer than XD™ and is designed for road hub applications. XDR™ driver bodies are compatible with all XD™ cassettes when the cassette is installed with a 1.85mm spacer.
Road bikes are faster and more capable than ever before, and riders are expanding what's possible with drop bikes.X-Range is grading for today's road riding. We completely reimagined road gearing for wider range, more useful and smoother gear progression, as well as smarter shift settings- enables by AXS. With X-Range, you're always in the right gear.
