Is that something you think you could tolerate? If it meant you could have a light, strong full size folder with full size wheels that folds into a space the size of a trekking backback?
I've ridden bikes where I have either thin bags on the top tube or tied stuff on there and I think after about 80mm I tend to knock my knees on whatever it is. I could tolerate 100mm, but I think 140mm would be wide enough to be very annoying.
