Problem with chain when jumping to smallest gear

[devonserden]

Hello, I don't understand why the chain always skips the smallest gear when shifting back. I cleaned and lubricated it and also tried to align it but still couldn't solve the problem. Does anyone know the cause and how to fix it? Thank

Not sure what you mean

How can it skip the smallest cog?  Either it will be in the smallest cog or it won't shift there.  It can't skip it as it is not inbetween anything, it is at the end

If you literarily mean the smallest gear (least gear inches) then this is also true for the largest cog
