Thank you, and good eye! I'm glad somebody addressed that (kind of like an Easter egg)! It actually does not rub when you pedal, the top section pulls tighter and the bottom section just barely clears the tube. It had me worried, and does not fit on my stand, so I had to hang it up from the ceiling so I could see it better. I did have to grind away a bit of the kickstand mount for clearance though.One of my fav for the moment. Rat's must be brutal sometimes. I guess you have a problem with the chain, I hope you will fix it soon.
