Made from aluminium, this chainring delivers incredible efficiency thanks to X-Sync technology. The thickness of each tooth is CNC-machined with extreme precision to perfectly match both the inner and outer chain links, while the large squared serrated edges allow faster chain engagement than traditional triangular teeth, for optimal control and absolute efficiency.
Available in 14, 16 and 18 teeth, this chainring is designed to be used with a Bosch motor.
