The Colombian Jarlinson Pantano bagged stage 15 at the Tour de France, the first for his Swiss team IAM Cycling.
His outfit are only professional Swiss team and the win comes the day before the race will visit Switzerland.
The 159km stage from Bourg-en-Bresse – Culoz, included the out-of-category, leg sapping Grand Colombier which peaks at 1500m.
A 30-man group broke away on the first of the six ascents of the day, up the Col du Berthiand. But Pantano and Saxo Tinkoff’s Rafal Majka distanced themselves on the finishing circuit, which included the climb of the Lacets du Grand Colombier.
Pantano was dropped on the climb but bridged the gap on the descent to Majka, where the two worked together to the finish line.
It was a relatively easy day for Team Sky, which quashed any dissent from rivals such as Astana’s Fabio Aru.
Pantano outsprinted the Polish champion to the line for his team’s maiden tour win.
For the yellow jersey, that remains on the back of Team Sky Froome, who retains the overall lead.
