Abstract: A handlebar/stem attachment interface with minimal frontal area comprises a handlebar body and a stem between which is disposed a threaded element to screw or unscrew the stem. By such arrangements, it is convenient for the user to replace the handlebar as desired, and the smooth even configuration of the handlebar body can further reduce the drag coefficient of the bicycle while increasing the riding rate.

Abstract: Uneven parallel bars commonly used by female gymnasts have a resilient pad mounted on the lower of the bars for protecting vulnerable parts of the gymnast's body from injury during extensive contact with the lower bar. The pad has a cylindrically shaped tube constructed from a covered core of a resilient material, and is provided with a slot extending along the entire length of the tube. By shaping the slot to the cross section of the lower bar for mating with the latter, the pad is retainingly received on the lower bar. Further, straps can be provided on the tube for securing the pad to the lower bar.
