Adam Ondra is back in Czechia's Moravian Karst area, where he recently climbed Brutal Rider (V16). This time he's there to inspect a new route, one he's had his eye on for years.. In this video, Ondra demonstrates his process of bolting and cleaning the line, which he speculates could be 9c [5.15d].
At first, Ondra explained that he was just hoping the route would be possible. Upon bolting the line, he wrote, "The line turned out to be probably possible, and surely pretty hard!"
