曲柄組 - SRAM SX Eagle Crankset
FC-SX-1-A1

Multiple price-point options to allow you to hit the group price you need to build a better bike. Same chain retention performance as seen in all of the higher-level Eagle drivetrain cranks.

• All new fully featured Eagle crankset. Now offering more Eagle™ options than ever before.
• DUB technology option.
• Steel Eagle™ direct mount ring — as seen on NX Eagle™.
• For Powerspline cranks, use 118/73 Powerspline Bottom Brackets.

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 technology represents our newest 1X drivetrain technology. Eagle is lighter, simpler, more durable, and easier to use drivetrain. Eagle features all-new 1X components, engineered for even greater durability and performance while maintaining a significant weight advantage over other drivetrain solutions. Eagle technology also provides an expanded gear range of 500%, which is equal to 2x11 drivetrains.

X-SYNC 2
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
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.
