The beginning isn't hard. Like 5.9. Then it's getting really hard, no feet, very tiny holds in a overhang. The crux is in the 2/3 of the route, where it shift to the left. The 2 last bolts are easier though.
Me and my friend tried this route without knowing the grade. With a lot of work, my friend did complete it. I have to admit that I only went to the top to pick up is gear by cheating.
