曲柄組- XX1 Eagle DUB SL Crankset
FC-XX-1-C1

True competitors are always looking for a performance advantage - a relentless pursuit of equipment that is lighter, stiffer, stronger and more durable. To create the best drivetrain possible, we re-examined and re-engineered our crankset design. Our all-new XX1 Eagle™ CARBON TUNED™ crankset is our lightest, stiffest and strongest to date. DUB™ technology enhances this by simplifying the relationship of the spindle to the bottom bracket, and redefining the measure of durability. DUB-powered cranksets mean simplicity, compatibility, and durability.

• DUB™ technology delivers the lightest, stiffest, strongest crankset available
• All-new SRAM CARBON TUNED™ crank technology provides extreme stiffness and light weight
• All-new chainring technology is designed specifically for Eagle™ chains and drivetrains
• The X-SYNC 2™ chainring provides significantly quieter performance, with better mud clearing and extraordinary durability

CARBON TUNED
Strength and stiffness where you need it, lightweight like you want it. Proprietary SRAM carbon lay-up design increases thickness and stiffness in critical stress areas. Tapered, terraced, carb on architecture ensures the greatest weight savings without compromising strength.

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-SYNCT Eagle is the next evolution of SRAM X-SYNC⁻¹* technology. The aggressive teeth design provides better chain retention for a smoother, more efficient pedal feel. With a focus on long wear-life, the X-SYNCW2 Eagle™ design reduces friction and the accumulation of mud, grit, and grime.

DUB 五通軸承
DUB 技術的核心，在於五通中軸與軸承的配合方式，此部位正是剛性與耐用度的關鍵要素。我們進一步超越傳統思維，並將所有紛亂的規格化繁為簡，更有效地整合了齒盤、曲柄、軸心和五通軸承之間的關係。透過這種方式，開發出性能更加優異的完整傳動套件系統。
