The compact crankset adopts the Power-Torque system, which makes it possible to obtain very high values of torsional stiffness and efficient power transmission, without increasing the lateral bulk. Thanks to the oversize axle and external cups, the system is very rigid, but unlike other systems that are broadened in the ankle area because of the external cups, the Athena crankset does not make it necessary to change the pedalling position. More rigid and lighter, it transfers the force exerted by the athlete without wastage and with maximum ergonomics.
The XPSS (Extreme Performance Shifting System) chainrings improve shifting timing with front derailleur. The tooth design is designed to optimize 11-speed EPS operation. Shifting to "higher quality"; the new chainrings have 8 pins to lift the chain and 2 to lower it. This whole redesigned system makes shifting from one chainring to the other very fast and efficient. The result: faster and more precise shifting. The big chainring is assembled directly through 5 screws into the small chainring which is now threatened. This allows an easier assembly and makes the system lighter, more stiff and safe. The chainrings are hard anodized to get a greater resistance to wear and saline corrosion. Integrated Power-Torque axle. Requires Power-Torque BB cups.
Power-Torque bottom bracket cups are not included in delivery!
