Kristoffersen retook the lead in the overall World Cup standings, though conceded the giant slalom points lead to Kranjec.
First-run leader Luca De Aliprandini was ahead at the time checks when he skied out halfway down, sliding away on his right hip.
Fast-changing light on the storied Chuenisbaergli course again seemed to be a factor. The bright sunshine dives behind the surrounding mountains at around 2 p.m. local time, making the course darker and trickier for the first-run leaders to pick the best racing line.
The four men on the podium Saturday were all outside the top five going into the second leg, where the top 30 start in reverse order. None of the top five in the morning ended within one second of the winner.
Kranjec’s second career World Cup win extended a run of 10 straight top-10 finishes since his debut victory last season at Saalbach, Austria. He was also fourth in the 2018 Pyeongchang Olympics giant slalom, won by now-retired great Marcel Hirscher.
The wide-open race Saturday followed Marcel Hirscher sweeping the giant slalom and slalom races at Adelboden for the last two seasons.
Even without Hirscher leading its rival and neighbor Austria, Switzerland could not place a racer on the podium at its classic giant slalom, which featured in the original week of World Cup racing in January 1967.
No Swiss man has finished in the top three since 2008, and Loic Meillard could not end the streak Saturday despite being third fastest and only 0.11 back in the first run.
Meillard fell out of contention in the fading light to end 1.97 back in 17th.
The best-placed American was Ted Ligety, who won at Adelboden in 2013 during his years dominating the discipline. Ligety moved up from 14th to seventh, ending 0.95 behind Kranjec.
Tommy Ford, the giant slalom winner last month on home snow at Beaver Creek, Colorado, quickly crashed out of the first run.
A slalom completes the Adelboden meeting on Sunday.
