For the artist, the challenge of the solution is the inspiration to create. The crank arm—perfected in performance by SRAM engineers—is a utilitarian canvas begging to be transformed. Troy Lee, design artist, took to that canvas. And now, those of us who have seen can never unsee. It’s the crank, made more. Same same. But forever different.
The unit consisting of crankshaft and bottom bracket is the heart of the DUB technology. Here stiffness meets durability. SRAM has gone a step further and made everything even easier and better. It's the system approach through the integration of chainring, crank, shaft and bottom bracket that means better drive performance.
X-SYNC 2 Eagle is the latest development of the SRAM X-SYNC technology. The tooth profile of the chainring increases chain tension and pedalling efficiency. The service life of the chainring is longer because the X-SYNC-EAGLE technology reduces friction and dirt.
