In a joint research and development project with the University of Helsinki, Rex successfully transformed the hot black Diamond wax, from records, into liquid form. With the new Rex Black Magik drop wax, the advantages of applying hot wax are obtained, such as extreme cleaning, low friction and effective protection from wear, combined with the ease of use of lubricants in a bottle. Black Magik is generous in the use and its composition fits perfectly to the mixture of Black Diamond 11+1 wax blocks. Black Diamond hot wax has been tested to be hot wax for leading chains on the market, both in dry conditions and, above all, in wet conditions. Black Magik is also the perfect and 100% compatible complement with Rex Black Diamond hot wax, and offers the same performance too. Unlike most skiolins with the emulsion of the competition, Black Magik has an identical composition to hot dissolving. It does not collect dirty or accumulate in the derailler's pulleys and in the pulleys.
