Chris King components amaze me. I installed a CK 1" threadless headset in my Bianchi Pista back in 2005. I think in 2006 I overhauled it, though it didn't need it. Today I decided it was time, although it felt smooth as butter. Upon removing the top cap from the upper stack I simply marveled in disbelief... it was immaculate... there was still red lithium grease from the overhaul I performed three years ago. Wow. There wasn't a spec of debris to be found. The inside of my steerer tube was filthy of course, but the headset was impeccably clean! I'll be installing a CK headset on my singlespeed first chance I get.
