Purchased for use with Shimano 105/11 speed transmission. For use, we spray the silicone spray "Tsuru to" inside the cable. When making confirmation at the time of cable processing, it is making the same as made by Shimano. Since it is not a full outer cable wiring, the influence is also little, but the difference was not felt in the shift performance after mounting. It is somewhat cheaper than the Shimano product as a price, it is possible to reduce the cost.
