Chromosome Y 8c+ (9a) flash by Alex Megos
Alex Megos, who the last week flashed his second 9a, reports on Insta that he has flashed Chromosome Y 8c+ (9a) in Charmery. The beta he got from Alexander Rohr. "I do agree though with most repeaters and I also think it's rather 8c+."
Later he tried Pirmin Bertle's harder version, Meiose giving a personal 9a grade. In total. the German has now done 101 routes 8c+/9a and harder which is second-most in the world after Adam Ondra. "The way @pirminbertle climbed it, it is 9a+. That's not the way it makes sense to me though as it eliminates some holds that are totally in reach and in the line too."
So what about calling Bertle's version Meiose eliminate 9a+?
Yeah maybe. It just isn't very clear what's allowed to grab and what's not. I know the way I climbed it is easier than what Pirmin did but I could still clip all the bolts and I was always in reach of the line of bolts.

Ondra flashes 3*8C in two weeks
โI stopped focusing on competition bouldering after last yearโs World Cup in Prague, partly because I can already feel it on my body, especially in my shoulders. The modern competition style, with a lot of jumping from one hold to another, is very demanding for the shoulders.
