This week's video comes from the Frankenjura where Moon climber Buster Martin is working the Wolfgang Güllich route, Action Directe 9a. First climbed by Wolfgang in 1991, the pocket pulling test piece was awarded the grade of 8c+ which, like Ben Moon's route Hubble which was climbed the year before, marked a serious step up in sport climbing standards around the world. Now some years later, both routes have been given 9a and Moon athlete Buster Martin is vying to become only the second climber after Alex Megos to have climbed both legendary routes. Can he stick Action Directe's famous mono dyno move? Watch below to find out!
