Abstract
The set of bicycle headsets that are threadless and/or have pressed frame cups/races can be locked to prohibit the nominal rotation of the headset and bicycle handlebars about the bicycle's steer tube by this invention. This invention uses standard threadless headset components in addition to three newly invented components: The upper head tube race with spin-lock grooves, the external ring lock, and the headset spacer with spin-lock grooves. The locking configuration is achieved by mating male pins on the interior surface of the external ring lock with female spin-lock grooves that are on the exterior surfaces of the upper head tube race with spin-lock grooves and headset spacer with spin-lock grooves. There are a sets of spin-lock grooves that, when the male pins are mated accordingly, provide the locked and unlocked configurations of the headset.
