Someone has sent in a report about the lower-off bolts on Clue, So? (4c) at Trevor Quarry.
"The lower off bolts at the top of the climb were over 50% worn through from rope, the in situ crab was also very worn".
Sounds like a lot of people may have been top-roping direct through the bolts. It is the easiest route on the wall and sees a lot of ascents so it may just be general wear and tear but it is probably more likely to be from excessive top-roping.
A good reminder that only the last ascent of your group should actually thread the belay. Any top-roping should be done through quickdraws. If you are climbing with people who can't thread belays then either teach them to do it, or climb the route again yourself at the end of the day.
As for this belay, if anyone is in the area then a report back would be good and maybe take a replacement crab for the one that is said to have worn through.
