Sitstart in the back of the roof with a thin crack right hand, climb the overhang to the left, catch the big hold (lip) of the roof and mantle up above.Update (March 2021) from bleau.info: the undercling under the roof has broken off but the initial grade of 6b will probably not be revised.If you are short or have a small span with your arms like me, you can go a little further left before going for the lip above. There is a nice crack to hold onto which I used!
