Squirt is a wax-based lube. When compared to oil-based lubes, it noticeably decreases friction, noise and lasts longer. As an added bonus, you don't even have to clean squirt off your chain - just apply more whenever you need it! 

Squirt lube is one of our favourite chain lubricants. The alternative, which we prefer a bit more, is Smoove, which we sell here. Smoove is more expensive, but in our experience, it lasts longer and better reduces drivetrain noise.
