Unparalleled chain lubrication Since 1988, finish line® has dedicated itself to advancing the science of bicycle lubrication. Our Halo™ range represents our greatest achievement involving the tribology of reducing drivetrain friction and mechanical wear.Halo Wet chain lubricant is engineered for unparalleled drivetrain performance and long relubrication intervals in both clean/dry and wet conditions.Halo Wet chain lubricant is engineered for unparalleled drivetrain performance and long relubrication intervals in both clean/dry and wet conditions. Developed in a laboratory with state-of-the-art chemistries and field tested by leading professional teams, it delivers ultra-low friction, superior mileage, and advanced water and rust resistance. Halo? Wet is a liquid formula that goes on wet and is immediately ready to ride.Halo Wet bottles come complete with finish lines new patent-pending smart luber. It helps deliver a perfectly lubricated chain without the mess and waste of traditional lubricating Halo Lubricants are applied with finish lines new patent-pending smart luber. The smart luber represents a paradigm shift in the way bicycle lubricants are delivered onto a chain. It ensures no link is missed, no mess is made, no lubricant is wasted, and no time is lost when lubricating a chain for maximum performance.Key pointslow coefficient of frictionmaximum chain cleanlinessimproved drivetrain efficiencyultra-low chain and component wear for extended component lifeextreme pressure resistance for maximum power output under high torque pedallingextended intervals between relubricationreduced chain vibration and noiseperformance ingredients gas-to-liquid (gtl) - is a hydrodynamic fluid film synthesized from natural gas. Its unique molecular structure minimizes drivetrain noise, dramatically reduces friction, repels water, and maintains viscosity in extreme temperatures.Spherical tungsten - features a proprietary hollow core to help reduce vibrational friction caused by high torque pedalling. Micron Sized and spherical shape helps reduce sliding friction by creating a rolling effect on the surface of the chain.Ceramic - boron nitride platelets cover the chain to form a protective non-stick coating. This ceramic coating works synergistically with spherical tungsten to substantially reduce wear and help extend the life of drivetrain components.Instructionsshake vigorously and apply to a clean, dry chain.
