The Athena 11s crankset makes use of the Campagnolo Ultra-Torque system:

• Supersize design. The chainring has a new design that increases its rigidity for greater power transfer;
• The outer chainring is equipped with 8 pins, which facilitate the ascent of the chain in many more points with respect to other chainrings on the market;
• Synchronisation of the Ultra-Shift chainrings. The new 11s chainrings have been designed in such a way as to have two sectors specialised for ascent and two for descent, which makes shifting much faster and without hesitation;
• Ultra-Shift design of the teeth. The teeth of the inner chainring have an asymmetrical profile to facilitate the descent of the chain from the outer chainring;
• Weight: 869 g (aluminium version).
• FC10-AT
