Not the magent for sure.
As for spoke tension, I added value 1/4 of turn yesterday but really no difference. The "pinging" ,which sounds like spoke noise, made me think maybe the nipples are rubbing on the rim. So today after 50 miles we stopped and I added a drop of chain lube to each nipple. It seemed to quiet it a bit. Tomorrow is a rest day so I will fuss more . Otherwise I am just going to get a new wheel.
