Great Tire. Too Bad They Don't Fit
These are great tires. They ride well, corner great, and wear adequately. But I doubt I will ever buy another one. Conti tubular tires are sized just enough too small that they are next to impossible to mount. And I have mounted a lot of tires in my life. I had hoped the 4000 would be sized better, but no. Even after stretching them for a week at 140 pounds pressure they still fight you to a standstill when you try to mount them. I'm sticking to my Vittorias for tubies and Continentals for clinchers.I guess you could pay someone to mount them for you--but I am somewhat anal about knowing my tires are mounted correctly.
