Transfers aren't usually announced until after August 1, according to the UCI rules on the matter, but it's no secret that many teams have been chasing Sagan's signature and those of his Tinkoff teammates, with the team folding at the end of the year.
It has been rumoured for weeks that Bora are in pole position to sign the current world champion, with new title sponsor Hansgrohe and bike brand Specialized rumoured to be footing the substantial bill.
"I understand he signed with Bora," Tinkov said in an interview with ITV. "I will gladly follow Peter on TV, or over the net, and if I come some time to the race when Peter comes out of the Bora bus, he will not hesitate to take a photo with me."

And the sum paid for the man who's won three stages so far at the Tour de France isn't insignificant, with Tinkov saying the German team is paying Sagan more than the lucrative deal he's on with Tinkoff.
"According to my information, Bora paid him even more. I mean, that's the market," he said. "I know for definite he got more. I'm not going to disclose the number. But he signed for much more money than I paid him - that's a fact."
