曲柄腿 - GX Eagle DUB Crankset
FC-GX-1-C1

Some riders test their limits more than others. For these riders, the GX Eagle DUB crankset allows them to go all in, every day they ride. The best aluminum crankset we make, engineered to deliver consistent performance every ride. Featuring our X-SYNC 2 tooth profile chainring for complete chain control. Each tooth's thickness is toleranced and controlled to work seamlessly with the chain's inner and outer links. DUB technology’s patented spindle design and bottom bracket provides a uniform approach to fitment, better sealing and forward and backward compatibility. Simply put, the forged aluminum GX Eagle DUB crankset is the no frills choice of riders who know.

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-SYNC 2
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。
