Parafilm bike chain Lube goes on wet to penetrate ROLLERs and side plates, then sets up to a soft, pliable wax. Chain is encased in a protective layer and shielded from the harsh elements of dirt, grime & water. Special low melt point wax replenishes drivetrain by drip-feeding clean Lube from the inside layers outward, significantly reducing abrasive wear and eliminating corrosion. Smooth, quiet, trouble-free operation in all conditions. Waterproof. Long lasting protection for all cyclists.
