Rex specialty grease for bicycle applications. Utilizes the same raw materials that Rex use in their high-fluor ski waxes. This unique approach gives great properties: Ultra-low friction and good lubricant film creation on metal-to metal surface contacts. The fluorocarbon compounds further enhance the water repellency of the grease. Made at the Rex factory in Finland, using medical-grade grease and paraffins unlike typical industrial greases. In addition to PTFE and fluorocarbon compounds, the grease also contains a special anti-corrosive additive that further enhances protection against rust in headsets and bottom brackets. Excellent for headsets and other bearings, bottom brackets, suspension linkages and bushings, axle threads and bolts. Tested year-around in harsh Finnish climate by elite Finnish bikers.
