SP31 Inner Wire
SP31 Inner Wire made by Nissen Cable.
A wire material is stainless steel.
31 wires, which are more than a usual 19 wires, are assembled by a method called “Warrington Type”, formed by high density wires and each wire has different diameter. More wires decrease spaces between them and enhance the rigidity of stretching direction, and at the same time earns high flexibility. A tensile strength is 10% higher than a usual product.
Engraving a surface to make a perfect circle and moreover it applies plasma plating. Compared to a wire coated with fluorine, not only making the pull of brake lever much lighter, but also having higher coating durability.
Please have an amazing experience of the highest quality inner wire in the world, which is matured by an exquisite skill.
Pre-tension processing has examined.
