Claim Text:
1. A bicycle or scooter compression clamp adapted to bind a handlebar stem to a fork tube using a headset bearing such that the headset bearing can be preloaded via tightening of a compression mechanism, comprising: a longitudinal compression sleeve body; a first bore of a first diameter disposed at an end of the body, adapted for engaging the handlebar stem; a second bore of a smaller second diameter disposed at an other end of the body, adapted for engaging the fork tube, wherein the first bore and the second bore are substantially inline and coaxial to each other and meet within the body to form a circular lip defined by a difference in the first diameter and second diameter; a compression washer having a diameter greater than the second diameter, disposed upon the lip; a compression bolt with threads coupled to the compression washer, the threads within the second bore of the body; a fork tube gripping element adapted to couple to the compression bolt and the fork tube inserted within the second bore of the body, such that as the compression bolt is tightened, the fork tube is axially pulled towards the compression washer to preload the headset bearing; a longitudinal slot along the entire body, providing a gap from the first and second bore to an exterior of the body; and a rotation preventing tightening mechanism disposed about a portion of the body on opposing sides of the longitudinal slot, such that as the tightening mechanism is tightened, the longitudinal slot is compressed and the handlebar stem and the fork tube are secured to the body and prevented from rotating separately from the body.
