The X-Glide chainrings newly developed, in combination with the Yaw front derailleur for optimum switching performance. The rigid sheets (5 mm, 7075-T6 aluminum, CNC machined) feature shift pins in a modern design, which was acquired by SRAM XX. The CNC machining allows precise control of each tooth shape, each climber and almost any switching function of the rear sprocket. Chainrings, chain and derailleur form an integrated system for optimal performance.
