Saint-Gervais - Tom Dumoulin's fantastic Tour de France ended in pain and disappointment on Friday as the Dutchman quit following a crash.
Dumoulin injured his wrist, putting a question mark over his Olympic participation next month.
Having won two stages and finished second on Thursday's uphill time-trial, Dumoulin was enjoying a dream Tour, but it all went wrong 60km from the end of the 146km Alpine 19th stage.
The time-trial specialist was sitting comfortably in the peloton but innocuously lost control of his bike and crashed, injuring his wrist.
He was seen to by race medics and visibly in pain was forced to quit.
It comes at an awkward time less than three weeks away from the Olympic time-trial competition in Rio, in which he would be among the favourites.
