Description
This is a NISSEN SP31 inner wire. The wire is made of rust-resistant stainless steel.
The 31 strands, more than the standard 19, are formed using a technique called Warrington twist , in which strands of different diameters are densely packed together. The increased number of strands reduces the gaps between the strands, increasing rigidity in the elongation direction while also achieving greater flexibility. The tensile strength is also about 10% higher than conventional products.
The twisted wires are then ground to a nearly perfect circle and then plasma plated, which not only makes them easier to pull than wires with a fluorine coating, but also makes the coating more durable.
It also has a pre-tensioning process that applies force in advance to reduce initial stretching after installation on the bike.
Experience the high quality inner wire that is unparalleled in the world, refined with generous technology.
