Penz and Fischler pulled off the best time of the first run in Paramonovo, clocking 45.876 seconds, and repeated the trick second time out, this time posting 45.812, for a winning time of 1:31.688 minutes.
And with the final World Cup of the season doubling as the European Championships that ensured the doubles title remained in Austrian hands with the Linger brothers taking gold last time out in Sigulda.
It also ensured the Linger brothers ended the season with the overall World Cup title with Penz and Fischler’s win edging their nearest challengers for the title – Tobias Wendl and Tobias Arlt – down into second.
With Penz and Fischler the last pair out courtesy of their fastest first run, Wendl and Arlt, who posted 1:31.837, saw the World Cup taken away from them with a first-place finish turning out to be needed to overhaul the Linger brothers.
The Austrian pair could only manage sixth overall in 1:32.386 but did improve from 12th after the first run and it proved enough with second not enough for Wendl and Arlt in Paramonovo.
Toni Eggert and Sascha Benecken completed the podium in third for third overall in the World Cup with the Linger brothers ending the season with 730 points overall – Wendl and Arlt just 10 behind with 720.
