The French rock jock cued up a knee pad to soften the crux and gave the route a personal downgrade to 5.15a/9a+. Did the young crusher throw shade at the GOAT? Not a single shadow.
Work smarter, not harder. That was Sébastien Bouin’s strategy on Adam Ondra’s 2013 route “Iron Curtain” (5.15b/9b) at Norway’s Flatanger cave.
Utilizing a knee pad to help lighten the load on his shoulders during the crux, Bouin clipped a letter grade off the climb in his personal estimation. But make no mistake: his assignment of the route’s difficulty intended no disrespect to Ondra. The world’s best rock climber showed Bouin the ropes at Flatanger in the first place.
In a lengthy Instagram post by Bouin, he explained how he first got psyched on “Iron Curtain.”

“Back in 2013, I sent an email to Adam asking him if he will go to Flatanger during that summer. I was searching for a partner to climb with. I wasn’t expecting any answer; we didn’t know each other yet,” he wrote. “The following day, I had an answer, proposing a date to pick me up from the airport.”
At the cave, the duo and fellow climber Erick Grandelius fixated on “Iron Curtain.”
“The line looked so hard and beautiful. It was the first route [Ondra] crushed during this trip,” Bouin recalled. “I had the chance to belay him during the FA, and it was impressive. He was doing a crazy gaston move for the crux. This was savage.”
Anybody who’s watched Ondra climb knows that description of his style is more than fair. But to solve the route for himself 9 years later, Bouin took a less resistant path. Arriving at Flatanger this summer, he decided to leave himself “open” and follow inspiration. The approach led him straight to “Iron Curtain” and the first repeat of the route after a few attempts.
“It took me 14 tries to do it and five climbing days. I used kneepads to send it. I think the line is easier with kneepads. You can do the crux a bit differently. It’s still quite hard but less demanding on the shoulders and more of a conventional boulder problem,” Bouin explained. “The rock is so perfect, and the line is so cool.”
