 產品敘述 
有時候,為了設計出更好的產品,你需要讓傳統延續.SRAM RED®AXS™功率齒盤就是一個傑出的例子。通過將傳動範圍從前端移到後端,我們得以使用恆定的13齒齒 差,貫穿於所有兩片式牙盤的規格,進而可以提升變速表現並給予車手他們真正想要的檔位。專為電子變速設計,SRAM RED®牙盤是牙盤設計的一次巨大飛躍。

特色與優勢
.Deep Range™ 寬齒比技術可以給予你更大的齒比範圍和更細膩的檔位變化,你隨時都能找到合適的檔位
.精確乾脆的前端變速
.DUD™ 軸心讓耐用性和簡潔度均獲得了提升可升級為功率計

EXOGRAM
Our Hollow Carbon Construction starts in the crank arm and extends into the crank's spider, maximizing the stiffness to weight ratio.

DUB™
The relationship between bottom bracket spindle and bearing is the core of DUB™ technology. It's where stiffness meets durability. We took it a step beyond conventional thinking and made everything simpler-better integrating the relationship between chainring, crank, spindle and bottom bracket. Ifs this approach to developing a complete system that equals better drivetrain performance.

 

X-RANGE
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.
