The bolt issue must be solved

Nobody can for sure know if Adam Ondra made use of the bolt. It just might be that the judges made a wrong call and that Ondra should have been in the final. If Ondra was not called out, Mickael Mawem would not have made it to the Top-8 and Sean McColl would not have qualified to the Olympics. If a similar bolt incident would have happen in Tokyo 2020, there would have been a big scandal as possibly the podium ranking would have to wait like an hour before being official. Climbers stepping on bolts is something happening quite often so it is a problem that has to be taken care of. One possibly solution is just to ask the industry to develop an anti-friction cover that could be squeezed on top of the hanger. Alternatively, the hangers could possibly be made much smaller. If such solution is not possible, the route setters should clearly mark any hangers that the climbers need to pay attention to. Lastly, all hangers that are not in use should be removed from the wall.
