From Climbing: „On January 31, after 20 days of projecting and a mere week before leaving for a six-week trip to Europe, Adam Stack made the third ascent of Tommy Caldwell´s Kryptonite at the Fortress of Solitude near Rifle, Colorado. Originally graded 9a by Caldwell, Kryptonite´s grade came under scrutiny after François Legrand´s aggressive cleaning produced a hold that second ascentionist Yuji Hirayama said makes the route 8c+. Stack, however, chose to avoid the manufactured hold, calling his redpoint method Kryptonite au naturel and confirmed the 9a grade.“ Without having actually seen the debated hold, it´s impossible to pass any judgement in this case. One can of course argue that „if the hold´s there, it´s part of the route, but if the hold is chipped or just extensively cleaned… well.
