Adam Ondra has flashed Pirmin Bertle's Chromosome Y, 9a, in the Tribune sector at Charmey, Switzerland.

Both this route and its "sister route" Chromosome X, also 9a, were first climbed by Pirmin within 75 minutes of each other a couple of years ago.

Later the same day he made the first ascent of the direct version, Transcription, 9a, on his second attempt. The way I interpret it the two routes partly share the same line.

Adam has previously onsighted three 9a's and flashed one and in total he has now climbed 102 routes 9a or harder. Give or take... uhm rather just give.
