Family bikes of Kaeru are equipped with chain guard. This said, all bike chains collects some dirt and need a chain clean up once in a while. It does not mean you have to get your hands dirty. Rockn’ Roll GOLD is the best product ever. It cleans and lubricates simultaneously. It is not greasy and it does not stain the floor if dripped on.
Think about LaMer or Clé de Peau for your bike, but for $8 for 7 onces approx.
You don’t have to remove the chain to clean it, and lubricates it in a way that the chain (after thorough wiping) does not attract dirt as other traditional oils.
