I don't know about 1+3/8 27" tire but check to be sure there's enough room for them to fit. I converted an old Cannondale with Shimano 600 stuff to 700C so I could use tires wider than 1+1/4" about 35mm. IIRC the 700C tires I TRIED to use were 38mm with knobs ie they were street tires; but they would rub the chainstays.


In (many) years past I used 1 3/8" tires on the bike and they just
barely fit. It was necessary to shave off one outermost row of knobs
on cyclocross tires to fit, but that was enough.
