As stated, 2 Continental Grand Prix 4000 650 C - $75 tires. They are black in color.
I bought these new in the box of a forum member last December, but didn’t try to mount them until a few weeks ago. I don’t ride my tri bike that often. I had a lot of issues mounting these to my Ksyrium Elite wheels. I’ll spare the details, but I’m not messing with them any more. One was never mounted, the other did get put on my front wheel and was ridden for a Oly race – that’s it. Both were taken out of their package, but I still have the boxes. $75 for both – pics on request. PM if interested.
