Sprocket Strummer Superdura is designed with the latest innovations and our best technology. Compared with the Sprocket Strummer Ultralight, the Superdura model is lighter, uses stronger materials, has a sturdier construction, and features a smoother shifting mechanism.
On the smaller sprockets, CNC machining is performed on Steel material to achieve optimal weight efficiency without compromising material strength. Meanwhile, on the three larger sprockets at the rear, CNC machining is applied to AL-7075 material to create an extremely lightweight design while ensuring precise contact between the sprockets and chain. More detailed CNC machining is also performed on AL7075-T6 and Steel materials, resulting in a smoother and more responsive shifting mechanism by adding dedicated paths for chain movement between sprockets.
