[header] How to lubricate a bike [title] Choose a wet lube if you ride in the rain. [step] If you live in a rainy environment or frequently ride on wet, muddy trails, go for a wet chain lube. It's thicker, so heavy downpours and mud won't wash it away. 
If you live in a drier climate, choose a thinner chain lube marked for dry conditions. [substeps] You can find wet and dry bicycle lubricants online or at a bike shop.
