700cx32cm tires and it's a 64cm MB Cafe Noir flat-bar road bike that I've outfitted with a proper steel touring fork w/ and front rack.

In order to handle the additional weight I may also have to change to wheels with a higher spoke count as well. It came with 20f/24r spoke Shimano WH-r500 which have been just fine so far, only a few loose spokes here and there.
