I met a gent on my cycle home Friday, who mentioned he had three chains for his bike. I said I thought it odd to have a chain for different types of route (my first thought) He explained that he "rotates them once month and they last longer"
I suppressed my initial response "don't they rotate as you cycle?" but that meant he moved on to another subject.
My question - what does he mean and does it help chains last longer? Does giving the chain a rest help prevent it stretching?
