I had a problem on my Colnago right after I got it. The wheels are 70's Super Champion , which I have multiple sets , 700c , never had a problem. This set of wheels were a struggle to get the wire bead tires( Pasela , just like my others) on and off to repair flats I switched the Velox tape which is what I always used , to the stuff that Trek bike store sells . It looks like narrow electrical tape ( I think it comes in different widths) . I took the time to go around the wheel and carefully file down the holes over the spoke tips ( burrs) , cleaned the old Velox tape residue and it worked! I don't have to panic when I get a flat while riding . I can pull the tire off , replace the tube , and be on my way. I used be on the side of the road going through the alphabet of bad words while hoping not to break a plastic tire lever.
