Founded in 1952, Rex is a ski wax manufacturer. Their production plant is located in Hartola, Finland. It is still a privately owned family business.
Their bicycle product line was launched in 2015. With the use of racing ski wax raw materials, their chain lubes have become a favourite among many national champions and die-hard cyclists.
In independent testing, Rex Black Diamond Chain lube has proven to be one of the most efficient lubricants in terms of friction and longevity. It is now also available as a solid base wax product.
