ATHENA™ Power-Torque™ 11 Speed aluminum crankset
The most evident changes are immediately noticed on the first shift. The new design of the chain up shift and downshift zones makes shifting extremely fast and precise.
The axle of Athena™ is the brand new Power Torque System™, which makes it possible to obtain very high values of torsional stiffness and efficient power transmission, without increasing the lateral bulk.
The crankset is also available in the carbon fibre version that is more than 100 grams lighter.

FEATURES & BENEFITS
- OPTIMAL POSITIONING OF THE BALL BEARING SEAT: Reduces friction to the minimum, reduces mechanical stress, and protects the ball bearings from water and dust to assure consistent performance over time.
- OPTIMISED U AND Q FACTORS: space optimised between ankle and crank - maximum lateral and torsional stiffness.
* The nominal weight refers to the lighter specification among the available options. The weight of the hubs does not includes the quick-release.
The nominal weight does not take account of the sometimes considerable quantities of grease used in the assembly of the products.
