Profile Racing’s U.S. patent (#6,874,385 B2) is titled "Bicycle Handlebar-Fork Clamp Assembly." The H.I.P. Stem utilizes a removable piston inside a clamp joining a bicycle handlebar to a fork tube. The key element of the Profile Racing H.I.P. invention is a three-piece clamp assembly. A rear housing has a vertical bore for receipt of a fork tube and a horizontal bore enclosing a movable piston, the piston being slightly longer than the horizontal bore. A front housing has a rear concave portion that together with a front concave portion of the rear housing grips a bicycle handlebar when the front housing is attached to the back housing by multiple bolts connecting the front housing and a front portion of the rear housing. As the bolts are tightened, the piston is moved backwards to tightly engage the fork tube.
