Hi, just got my new road bike and rode it three times (About 100km). Now I was wondering how many times should you clean your bike chain. Mine looks like this and it makes a crunching sound whenever I pedal (there's some kind of sand on it). Should I clean my chain now, or can it wait?3yr ⋅ Cycling-Tom ⋅ r/bikewrench
