As y'all know I just bought a Soma Rush with a matching threadless fork in khaki green. I always use a front brake when riding fixed on the road, so I expect the fork to be drilled for a front brake, which it was. I also expect it the be drilled for a modern brake with a recessed nut, which it wasn't. Instead, it was drilled for an old school brake with a throughbolt and external nut / washer. It also lacked a flat at the front and was curved, requiring a concave / flat washer like old school forks. Fortunately I had a washer in my parts bin, since I have a lot of vintage bikes, and was able to bore the hole at the back to accept a recessed nut. However, I did not have a counter-bore bit, so the nut is not recessed. The stock nut was too short, and the longest nut I had in my parts bin catches only about 5mm of thread, so as soon as I can get to my lbs I'm going to get a longer one. Anyway, just another example of how unanticipated details can affect a new build, and you never know what surprise is in store.
