Germany's Tony Martin took the lead in the Tour de France on Tuesday by attacking late on stage four on an ill-fitting bike that he borrowed on the fly from one of his teammates.
On the last of several cobblestoned sections, Martin got a flat tire. Normally he'd just grab his spare bike from his team's car, but the car was stuck in traffic behind the select group of about 35 riders he was racing with.
Martin's teammate Matteo Trentin was with him at the time of the puncture and told him to just take his bike.
Trentin's bike is a few centimeters larger than Martin's and the brakes are reversed — the rear brake is on the left side of the handlebar and the front on the right.
But it didn't matter as Martin pulled out one of the biggest wins of his career after attacking with 3.3 kilometers to go to the finish line, just holding off Paris-Roubaix winner John Degenkolb by 3 seconds.
With the win he donned his first yellow jersey, one of cycling's most coveted prizes.
He said it was "super difficult" to pull it off as he was trying to deal with the borrowed bike and his rivals for stage victory.
"I think I put out more watts than I ever did," said an exhausted and emotional Martin.
Martin, a three-time world time-trial champion, now leads the Tour by 12 seconds over previous leader Chris Froome, the Kenyan-born UK rider who won the 2013 Tour.
"Pure happiness! All the pressure and all the sadness from the last days has come off now," said the Etixx-Quick-Step rider, AFP reported. "It's a really emotional day and stage for me, I'm super happy for that. Everything went well and I'm super happy for this team."
The Tour started on July 4 in Utrecht, the Netherlands, and finishes in Paris on July 26.
