For a faster and more accurate change action, the larger center diameter upper sheave design keeps the space between change and cassette constant throughout all the crowns. X-Sync is the narrow tooth-width pattern machined by CNC, which is repeated throughout the entire plate, perfectly replicating the shape of the chain for maximum control. With Cage Lock system for easy removal and installation of the wheel. Characteristics: - Speeds: 11 - Long box - Weight: 220 g - Compatibility: X-Actuation, XX1 11 speeds - Roldanas: 12 teeth X-Sync
