Simply put the Chris King 2Nut headset is the finest example of the classic 1" threaded headset you can currently purchase. The 2Nut headset is the original 1" threaded headset design that uses a standard locknut and a nutted adjustable cup. Spacers can be used in between the locknut and adjustable cup to increase stack height and raise rider position.
All parts or perfectly machined and polished to a high luster. The silver headset has a classic look while the black has the stealth black-on-black Sotto Voce look. The tolerances on the 2Nut are literally perfect and highlights include light in weight, smooth action & incredibly durability. Clearly the ultimate in performance for your 1" threaded fork and frame.
