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?

I thought knc were reusable a few times and Shimano not.
I bought 2 kmc chains for £20 and then decided it can be a consumable item.
KMC make both, re-usable and the other sort. The reusable variety have an R in the product code, and “re-usable” on the packet!In the photo, the dark one is reusable, the silver one is not.
I’m sure someone has based a scientific paper around chain wear, if not there is a potential PhD for someone
Not quite a PhD, but there was an engineering student buying used cassettes on EBay in 2018, who I corresponded with, as he wanted to know the maintenance regime the original owners had used. After detailed examination of wear to cassettes, he said his findings showed that big brand solvent-borne lubricants didn’t do a good job at all, leading to direct metal-to-metal contact, and thus added wear. I seem to remember that he concluded that light machine oil was the best chain lubricant. I’ve used sewing machine oil ever since!
