Professional lubricant for bikes based on wax, enriched with a friction modifier, which forms a thin, flexible lubricating coating. Once applied, the liquid penetrated into the inner side of the chian. The wax leaves a lubricating coating which repels dirt. Wax products contain less lubricating properties than oils (like extra dry lube), therefore it has to be re-applied regularly. 

Application 

Use dry wax on the chian and let it dry long enough. Dry wax protects the chain against dirt. For good maintenance repeat the treatment sufficiently. For mountainbike use.  Don't use dry wax at freezing temperatures.
