曲柄組 - SRAM RED CRANKSET
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.
