11-speed chainring with an asymmetric fixed dimension of 110 mm, which is the same as Shimano's Dura Ace 11-speed blades/crankset.

The gear change is optimized for the Dura Ace series, so it will run just as well as a blade from Shimano.

Teflon coated.

Nice black color that allows you to change the appearance of your crankset.

Made in 7075 Aluminium.
