Saw this booth at Dirt Demo and it caught my attention because it’s something I’ve never seen before. The idea of “proper chain lubing technique” is highly debatable such as religion and politics. With the photos below, I hope you can formulate your own opinions about this product.
The idea is to pour in your favorite lube in the bottle, press against chain, then squeeze bottle while turning the crank. They said that the bottle can handle stuff like White Lightning.
Though the bike is upside down, they recommend using gravity to apply the lube while squeezing.
