High temperature specification using their unique technology (RSX9, 12, 15 only)

The RSX9, 12 and 15 are made of stainless steel that has been subjected to proprietary technology and heat treatment, and can be used at a maximum operating temperature of 150°C. In addition, the high-temperature grease contained in the RSX9, 12, and 15 reduces fluctuations in rolling resistance due to the grease even when the temperature changes from room temperature to high temperature.
