Hi fellow folder users! I have started using a folder for commuting to work(mu uno), I fold it up when I get to work and carry it inside to store. The chain is now nice and clean, being new, but I wonder if it will become a problem as it wears and gets dirty. I've considered a chain guard, but wonder if anyone else has found one useful/necessary. I work in a hospital, so cleanliness is a concern.
Thanks, Mike
