User serviceable and likely to outlast a few frames. Chris King designed the first sealed bearing headset in 1976. Thirty-four years later, the King headset remains a benchmark for quality. No other bicycle component can claim the precision, performance and absolute reliability of a Chris King headset. Chris King sealed bearing headsets now feature the Sotto Voce logo mark in all available colors. Sotto Voce (sot-toh voh-che) is an Italian term used in music to denote a dramatic lowering of the tone. It literally means “under voice” but can be translated as “soft voice”.
