曲柄組 - NX Eagle DUB Crankset
FC-NX-1-C1

The SRAM NX crankset delivers Eagle™ styling and performance to the newest addition to the Eagle™ ecosystem. Designed for SRAM's X-SYNC™2 chainrings, the NX crankset is engineered for complete chain control-each tooth's profile is precisely engineered to work quietly, efficiently and securely with the Eagle™ chain's inner and outer links. DUB™ technology features a better-engineered bottom bracket and a new spindle design, which together allows for a more uniform approach to bottom bracket fitment, better sealing against contamination and forward and backward compatibility. Now everyone can benefit from a new measure of performance and durability.

• 6000 series forged aluminum arms
• DUB™ technology features a uniform approach to bottom bracket fitment, better sealing against contamination and is forward and backward compatible.

BOOST
“ BOOST”是標準輪組和動力傳動系統的規範，它為幾何車架提供更多機會，它具有更短的鏈條、粗勇的避震樞軸、更廣的齒片規格可選擇以及更大的輪胎間隙和更寬更硬的輪組。

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-SYNC2
SRAM X-SYNC™2 Eagle is the next evolution of SRAM X-SYNC™ technology. The aggressive teeth design provides better chain「etention for a smoother, more efficient pedal feel. With a focus on long wear-life, the X-SYNC™2 Eagle™ design reduces friction and the accumulation of mud, grit, and grime.

DUB
軸心和軸承之間的關係是 DUB™ 技術的核心。這是剛性和耐久性之間的均衡。我們超越了傳統思維，使一切變得更加簡單，並更好地統一了盤片，曲柄， 軸心和中軸之間的關係。正是這種簡單的系統，擁有更好的傳動性能。
