Perfection is a shy and elusive target, crawling ever further back into the crevice between measurement and asymptote, between real and ideal.
That having been said, the bike now feels 99.9% dialed-in. That only took, what, almost a year? (To be fair, the thing that took the longest was the drivetrain, and I made one costly mistake there, with cascading consequences. I suspect that I’ll turn the next one, whenever and whatever it might be, around much more quickly.)
