Kittel and Renshaw both finished just under 45 minutes behind stage victor Geraint Thomas of Team Sky but still failed to make the cut.
Normally it's the competitors who are the centre of attention at the Tour de France, but it was a bike of a different kind grabbing all the headlines during stage 10.
Geraint Thomas's second consecutive stage win was greeted by booing and whistling at the climax of an ill-tempered stage during which Chris Froome was shoved by one spectator and the former Tour de France victor Vincenzo Nibali was brought down by a race motorbike.
But the Welshman and teammate Chris Froome were met by a chorus of boos and jeers at the finish as Team Sky's domination of the race continued.
The most serious of these incidents involved Vincenzo Nibali (Bahrain Merida) who fell as the result of two motorbikes and the crowd coming together.
Thomas dons the yellow jersey for a second straight Tour. "My back hurts. I had trouble breathing and now I don't feel well standing", the Italian said after the stage.
"It's unreal", Thomas said aftrewards.

Liverpool signs Brazilian goalkeeper Alisson from Roma
Liverpool are expected to finalise the deal for Alisson this weekend for a fee of €75million. In 37 Serie A games last season, he kept 17 clean sheets and made 107 saves, per Squawka .
The last Tour de France race leader to triumph on the Alpe was Armstrong, who was wearing the yellow jersey when he won a time trial in 2004. "I didn't expect it at all". When Dumoulin tried to ride away a short time later, Thomas marked the move.
Thomas now looks every inch a potential Tour victor, yet he still maintains Froome is Team Sky's designated leader and that he has not targeted final victory. 'I'm not sure what happened to Nibali, ' he said.
Thomas has publicly remained loyal to Froome in interviews. As long as we're not racing against each other, that's the main thing.
"I'll enjoy the moment and take it day by day".
Sky's rivals were intent on redressing the balance on the third and final day in the Alps.
Part of an early breakaway group, Dutch rider Steven Kruijswijk launched a solo attack up the Col de la Croix-de-Fer and crossed the summit above the tree-line with a six-minute lead over the peloton.
