Sprocket Strummer Superdura is designed with the latest innovations and our best technology. Compared to the Sprocket Strummer Ultralight, the Superdura model is lighter, made from stronger materials, has a sturdier construction, and features smoother shifting mechanisms.
On the small cog, CNC machining is performed on Steel material to achieve optimal weight efficiency without compromising material strength. Meanwhile, on the three large cogs at the back, CNC machining is applied to AL-7075 material to create a very lightweight while ensuring precise contact between the cog and chain. More detailed CNC processes are also performed on AL7075-T6 and Steel materials, resulting in smoother and more responsive shifting mechanisms by adding a special path for chain shifting between cogs.
