Thanks for the info. I'm trying to convince myself at over 230 lbs that I can comfortably ride 28mm tires right now on the Centurion Sport DLX. I probably will hold off on another "skinny tire bike" especially concidering that there's a ridden hard and put away wet Trek 728 in the back of my car right now... Love me some first world problems....
PS
The diamond back is on facebook marketplace place in Easton PA if anyone is interested.
