chain maintenance for indoor trainer bike
Silly question, but I was wondering, if I've been riding my bike indoors all winter, is there any reason to clean/lubricate it periodically? Clearly, I'm not very knowledgable on the workings of lubrication and the rate at which it wears off.
p.s. I know sweat can be a factor, but actually it turns out I don't sweat onto the chain and such really. Don't know if that's a consideration here.
