I'm sure this has been discussed before, but a quick search didn't bring up what I was looking for. I have recently bought two SDURO FullNine E-Bikes for my wife & I. I will get one new chain to keep on hand. Initially I will be washing the chains on the bikes when required. But eventually the pre-installed lubricant will be all washed out. So at this point the new chain will be fitted & the dirty one left to soak in cleaning solution. My question is: What is the lubricant the manufactures put in the new chains?
