Hot waxing is an increasingly popular method of lubricating bicycle chains. The solid wax does not collect dirt, keeps the entire bike drivetrain clean and repels dirt more effectively than traditional chain lubricants. BLACK DIAMOND HOT WAX combines Black Diamond's proven and effective additive technology with Rex's 70 years of waxing experience. Switching to hot wax makes cleaning your bike much easier and dramatically reduces wear on drivetrain components over extended use. Hot waxed chains leave no stains and do not require strong solvents for cleaning. On the contrary, they can be cleaned simply with warm water.
