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.
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.
DIFFERENTIATED CHAIN UPSHIFT AND DOWNSHIFT ZONES
