For fork upper tubes, our proprietary Kyokote process is second to none. The Kyokote process is equal in low friction performance to Kashima, but exceeds Kashima performance in heat transfer and toughness. Kyokote is a polymer impregnated hard anodize. The aluminum tubes are hard anodized, then impregnated with a special teflon polymer blend and sealed resulting in a hard, low friction surface (coefficient of static friction less than 0.05) with high thermal conductivity and excellent toughness. Unlike Kashima, Kyocote is done locally for quick turn around and available in both black and clear (clear typically comes out grey-gold in color).
