The 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 a smoother shifting mechanism.
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 light weight while ensuring precise contact between the cog and chain. More detailed CNC processes are also carried out on AL7075-T6 and Steel materials, resulting in a smoother and more responsive shifting mechanism by adding a special path for chain shifting between cogs.
