You don't need that knurled nut. Just use regular chainring nuts/bolts. You'll have to pull the Quarq off the crank arm, but it's easier than dealing w/ the silly knurled nut on just one bolt. I have to build 30-40 Quarq cranksets every year for the team bikes and that works fine.
I don't have the Quarq on mine, just the hidden bolt that is so close to the crank arm there's no room to put a wrench. Do you suggest removing the spider from the crankarm in order to mount the chainrings direct to the stand-alone spider such that I can get to all 5 bolts? If so, then I just need to figure out what it takes to remove the spider from the crank arm.
