Campagnolo Chainring for Athena CT - XPSS | 110 mm | 11-speed - 50 Teeth

5-arm aluminium chainring with compact 110 mm bolt circle diameter for Campagnolo 11-speed drivetrain systems. Suitable for Athena CT (Carbon-Titanium) cranksets, model year 2011 to 2014.

The chainring features the X.P.S.S.™ system for perfect interaction of all shifting components.

Extreme Performance Shifting System (X.P.S.S.™)

To get the best possible performance from Campagnolo shifting components, the Campy Tech Lab™ developed the X.P.S.S.™ system based on the perfect combination and integration of all the components of a drivetrain.

Each individual tooth has its own design depending on its position on the chainring and has been specifically matched to the corresponding chain. Since shifting performance is determined by the functionality of the entire group, the chainring, chain and front derailleur are designed to work seamlessly together.

The latest technologies were used to achieve a chainring design that not only enables lightning-fast and problem-free shifting operations, but also ensures optimal running of the chain under load. With the help of mathematical functions and advanced software, the movement of the chain was meticulously simulated down to the smallest detail.
