S1NEO was/(still is?) a sponsor of Pervis. He bsically endorses them as a bike brand, and they sold that Chinese frame as their top track model with his "signature" on the top tube. Any of the road bikes that he was riding to warm up, or on the road were supplied by S1NEO.
If you guys noticed, he raced with many sponsor labels on his equipment, and this was because until the twilight of his career, he wasn't one of the French team's top aces. He showed promise as a junior at the World Champs, but because he wasn't that big of a guy, with a light build, he didn't end up putting out a lot of power when it came to racing in the big leagues. For years he languished in their 2nd tier of guys, never receiving the fully supported ride the others did. Because of this he sought out sponsors to cover the cost of many of his World Cup trips to compete at that level. It was only later in his career did he become the giant killer that Kenny was already. Someone in Francois' camp had cracked the code when it came to all out speed for the little guys. His contracts with his sponsors were still in effect, so you can see the names and labels all over his gear. Great investment on their part if you as me.
