Our most advanced aluminum crankset is also our most extraordinary. Precise engineering has produced crank arms that optimize the stiffness-to-weight ratio, with material placed only where needed. The integrated chainrings ensure flawless shifting across a range of gear ratios that meets your needs, with an overall weight reduction of over 50 grams compared to the previous generation.

X-Range™
Flattop
Flattop technology enables a narrower and lighter chain, allowing for quieter operation as well as increased strength and durability.
Yaw™
Yaw technology enables trimless shifting, as the derailleur cage follows an arc and is therefore at a constant angle relative to the chain. As a result, transitions are more direct and precise, delivering unprecedented front shifting performance.
