In the BMX world the integrated headset is king. It's almost indestructible, virtually fool-proof to install, light weight and even a sealed one is relatively inexpensive. We use integrated headsets on all of our higher end bikes and swear by them so much so that we decided to introduce our own.
Includes top bolt and star fangled nut. The headset is sealed and meets Campagnola spec 45º/45º.
