For a clean, smooth-pedaling drivetrain, look no further than Finish Line's Ceramic Wax Lubricant. Its ceramic bonding technology allows you to greatly extend your re-lubing intervals for maximum durability and convenience. In fact, every time you apply the lube, it builds on the ceramic coating and the result is a chain so slippery even dirt has a hard time sticking! Think efficient. Think quiet. Think Finish Line! - With each application the ceramic coating is enhanced, ultimately providing the durability of many oil-based lubricants - No wetness or stickiness so dirt and grime will not be attracted or absorbed by the lubricant - Helps avoid abrasive wear allowing parts to run more smoothly and last longer - As the white ceramic particles embed themselves on the chain they will displace grime, causing a grey or black film to form on top of the wax coating. Over 2-3 applications this will lessen or cease. This discoloration is normal and will not compromise performance.
