The third collaborative design made between Lugs Not Drugs and YellowBird. Again, we take inspiration from the Rotorelief series by Marcel Duchamp. This time we are offering a limited edition of 90 caps that are each numbered. The series of 90 consists of four colors. The first is a dark patina. It reads as BLACK. The second color is a DARK TEAL. It is a nod to those determined blades of grass that are already coming up. Spring is doing it’s thing. The third color in this group is IVORY. We wanted something light. I am excited to see how these ones look as the brass gets darker with age. Our final color is VIOLET. Again, spring is springing. This is a shade that just makes people smile. It’s good. (Just like all current NIGHTCAPS, they are designed to work with a 1-1/8” threadless headset. They also come with an American made titanium bolt)
