By way of background, I have a Chris King PF30 BB for a 30mm spindle crank installed in my gravel bike.
On a long gravel ride the other day, I was on a bumpy climb, and I dropped my front chainring on a downshift. According to the guy from Quarq, the chain must have hit my DFour91 spider in just the wrong way - it really did kill the power meter spider. I believe he said it was a freak accident, but he had heard of this thing happening, so I don't know how unusual this is. Anyway, that Quarq had a 30mm spindle. They have ceased production of that model in favor of Quarqs with their DUB spindle, and I am getting one of those as my warranty replacement.
CK stopped making its PF30 BBs and their associated adapters some time ago, before DUB was launched. The CK rep I talked to said I could try their DUB fit kit for their T47 BBs. That has the 30mm to 28.99mm reducer I need, plus spacers to preload the BB properly. He could not guarantee that this would work. So, do people on the forum have any alternative adapter kits they can think of, or should the CK kit work? (It's their DUB Fit Kit B.)
As a side note, I got that DFour91 with aluminum crankarms from Competitive Cyclist. The crankarms themselves aren't compatible with the spider, so Quarq is sending me new arms. The aluminum Quarq arms worked but they looked pretty cheap, and I'm pretty sure Quarq is all carbon arms now, so I guess I get an upgrade. But if anyone needs a pair of 165mm aluminum Quarq arms with a 30mm spindle but no spider, feel free to PM me, they're yours for the cost of shipping.
