I have a Super Mondia Special 1973 that takes a pretty wide tire. Who ever owned it prior to me changed it to 27" tires and I put some Michelin 27" x 1 1/4" Pro Tek tires on it . When inflated they check 1 3/8" wide! and they clear but not by much. It has Reynolds 531 tubing and nice Nervex lugs. I use it if I have to go over any gravel or dirt . If this bike still had its 700c wheels I am pretty sure your tires would work. I do have to deflate the rear tire to get the wheel off .
