If you think that team owner Oleg Tinkov would not approve of his rider's antics, think again, because the Russian was right there to give his man a handshake as he got back on his bike.
The bike swap clearly didn't affect Sagan's racing, as he sped back into the peloton and sprinted to second place on the stage, behind Team Sky's Elia Viviani.
