Tim P.wrote a review of Challenge Strada Bianca Tire - Clincher on March 26, 2019
Tried to use these tires with a set of rims that I have had no problems fitting tires to in the past. Once I had used every trick in the book and almost an hour to get one side of the tire on the rim it is almost impossible to get an inner tube under the tire as the whole tire was so tight against the rim - when not inflated the middle of the tire has less circumference than the edge! Again with a lot of effort managed to squeeze a tube under but with it so screwed up to get it in just blew as I pumped. Tried again a few times with the same result. It may be better with a 650 tube. If you are willing to give these a go do not use with carbon rims as either your rims or levers will break before you get the tire on. Same problem with the two tires I bought so presume this is not a one off.
