CeramicSpeed SRAM pulleys with eTap arm
SRAM eTap chainrings are an innovation of the Ceramic Speed brand, which was developed in cooperation with professional triathletes and tested during the development process. They are designed to increase the endurance of the rider by saving energy (up to 2.4 watts). At the same time, they have 17 teeth, which significantly reduce the radius of chain wrapping, thus contributing to less friction. Pulleys with an eTap arm significantly extend the life of the derailleur.
They are made of high quality materials.
