Dia-Compe NB-1 Headset 1" Threadless - Silver
Only 1 left in stock
We have had good experience with Dia-Compe and often use the CB-2 on frames with the 1 1/8" standard. If you're building with a threadless one-inch fork, the NB-1 is an option with a classic silver finish and aluminum cups.
The sealed cartridge bearings provide smooth steering and a low-maintenance headset. The NB-1 fits a 25.4 mm steerer tube, a frame with 30.2 mm headset seats, and a 26.4 mm crown race. Check the frame and fork dimensions before installation, as there are several different one-inch standards.
