NISSEN CABLE CO, LTD (Nissen Cable) SP31 Special Stainless Steel Inner Shimano before and after load

Flexibility (Flexible): The normal inner cable is composed of 19 strands of stranded wires, but this product is composed of 31 wires.Therefore, it is more flexible and flexible than conventional products.When the handle is too tight, the installation will be smooth.The handle is also lightweight.

Durability (long lifespan): It is twisted denser than conventional products, so there is less gap between wires.Therefore, the inner cable has less stretch.Superior load capacity.(Improved breaking strength of the inner cable itself is about 10%) The re-adjustment is reduced after installation.Pre-stretch processing (to reduce initial stretching, eliminate gaps between wires and reduce stretching after installation)

Low Friction (light pull): The surface of the cable has been slicked to make it closer to a real circle and then coated with a special coating (electrodeposited coating).Therefore, it has lower friction than just slick processes and PTFE coatings.The coating is also difficult to peel, so it stays light for a long time.

By cutting the surface of the cable closer to the real circle to reduce friction, the use of different thicknesses on the inside reduces flexibility and internal wear and increases durability.
