Three days ago, this was perfectly round. Three days ago I added a new cassette to it, added the rest of the new drivetrain to the rest of the bike and resumed using my properbike for commuting. A mere three days and thirty miles later, it's doing this:
It is wibbling because four or five spokes flop lifelessly when plunked. Several more are sounding very low notes. I tried to take a clip of them but my camera needed to be recharged. Fortunately I fitted a Travel Agent to the brake at the same time as the rest of the bits so I'll be able to get by with a bit of waggle until it can be properly unwaggled, but...
Is this going to keep happening whilst I continue to use panniers?
I never had this sort of wheel-as-consumable problem in the past, despite carrying fairly heavy masses in a rucksack fairly frequently. My weight hasn't moved out of a five-kilogramme range for twenty-five years so it's not me, but then my weight can be unweighted over particularly bad bumps (or at least suspended a little through flexed joints) which a pannier cannot do, but I've been avoiding cobbles for the past few days just to ease the wheel in gently.
What sort of rims and nipples do heavy people who ride tandems use? Presumably they're not stopping every thirty miles to re-tighten one-ninth of their spokes.
What do other 13-ish stone people who sometimes carry panniers of shopping use?
