Kittel and Renshaw both finished just under 45 minutes behind stage victor Geraint Thomas of Team Sky but still failed to make the cut.
La Rosire - Mark Cavendish's hopes of beating Eddy Merckx's record of 34 stage wins on the Tour de France were put on hold Wednesday when the British sprinter was sensationally eliminated from the Tour de France.
Sprint specialist Cavendish, who has 30 Tour stage wins to his name, crossed the line one hour, five minutes, and 33 seconds after stage victor Geraint Thomas, far outside the time limit that had been set at 31:27.
In front of him, lead-out man Renshaw, as well as Katusha-Alpecin's Kittel and his lieutenant Rick Zabel, had also missed the time cut but the other 161 riders to start the stage got in on time. He finished in a group 22 minutes after Thomas.
Thomas dons the yellow jersey for a second straight Tour. When Froome accelerated, I followed him, and I felt good, too, but then there was this slowing down, and I went down.
The Welshman took the stage win on the summit finish of La Rosière, riding way into the yellow jersey along with it.
But Thomas and Sky have played that down.
"It's just mental. I just can't believe I won the stage".
Sky's rivals were intent on redressing the balance on the third and final day in the Alps. When Dumoulin tried to ride away a short time later, Thomas marked the move.
