Our most advanced road bike aluminum crankset is also the most extraordinary. Careful engineering has produced cranks that optimize the stiffness-to-weight ratio, with material placed only where needed. The integrated chainrings ensure flawless gear changes across a range of 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 allows for adjustment-free 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, providing unprecedented front shifting performance.
