A handlebar attachment that can be clamped onto the existing handlebar of a bicycle or the like. The handlebar attachment permits the rider of the bicycle to assume an improved aerodynamic position while riding and places the rider in a position for permitting increased lung air intake. The attachment includes hand area elements, sliding elements and joint element for joining the hand area elements and the sliding elements. The assembly is attachable to existing handlebars with adjustable clamps.

1. A clamp-on aerodynamic handlebar attachment for a substantially straight handlebar that connects to a steering post of a bicycle forward of the bicycle seat, said handlebar consisting of a pair of bar portions one of said pair on each side of said steering post and having an axis substantially perpendicular to the frame of said bicycle to form said handlebar and establishing a straight handlebar portion on each side of said steering post with end portions at each end of said straight handlebar portions, said clamp-on aerodynamic handlebar attachment comprising: a) a pair of hand area elements, b) at least one sliding element, c) said hand area elements and said sliding element being joined at a joint so as to provide a free end for said hand area elements and a free end for said sliding element with said free ends of said hand area elements extending symetrically outwardly from said joint and said free end of said sliding element directed away from said joint and said free ends of said hand area elements, d) at least one adjustable handlebar clamp, said clamp including means for adjustably attaching said clamp to a bar portion on one side of said steering post, said clamp being adapted to slideably receive and adjustably hold said free end of said sliding element, e) said pair of hand area elements and said sliding element being an assembly adapted to be positioned with respect to and adjustably clamped on said handlebar by said clamp with said hand area elements forward of said steering post and positioned with respect to said handlebar and steering post with said free ends of said hand area elements directed toward said handlebar so as to permit a rider of said bicycle to rest the elbows of the rider on said bar portions forming said handlebar while grasping said hand area elements with the rider's hands. 2. A clamp-on aerodynamic handlebar attachment for a substantially straight handlebar that connects to a steering post forward of the bicycle seat, said handlebar consisting of a pair of extending straight bar portions one of said pair on each side of said steering post to form said handlebar and establishing a straight handlebar portion on each side of said steering post with end portions spaced from said steering post at each end of said straight handlebar portions, said clamp-on aerodynamic handlebar attachment comprising: a) a pair of hand area elements, b) a pair of sliding elements, c) a four way joint element, said four way joint element being adapted to: i) receive and hold said pair of hand area elements with the free ends of each hand area element in symetrical position with respect to each other with said free ends extending outwardly from said four way joint element and, ii) receive and hold said pair of sliding elements with the free ends of each sliding element in symetrical position with respect to each other and directed toward said handlebar of said bicycle, d) a pair of adjustable handlebar clamps, one of said pair being adjustably attachable to said bar portions on each side of said steering post, each of said clamps being adapted to adjustably slideably receive and hold said free end of one of said said sliding elements, e) said pair of hand elements, four way joint and pair of sliding elements being an assembly of said handlebar attachment adapted to be positioned with respect to said handlebar and clamped on said handlebar with said hand area elements forward of and directed toward said steering post and positioned by said sliding elements with respect to said handlebar and steering post so as to permit a rider of said bicycle to rest the elbows of the rider on said end portions of said bar portions while grasping said hand area elements with the rider's hands in comfortable normal hand/forearm alignment. 3. A clamp-on aerodynamic handlebar attachment for a substantially straight bicycle handlebar that connects to a steering post of a bicycle forward of the bicycle seat and consists of a pair of extending straight bar portions one on each side of said steering post and having an axis perpendicular to the frame of said bicycle to form said handlebar and establishing a straight handlebar portion on each side of said steering post with handlebar end portions spaced from said steering post at each end of said straight handlebar portions, said clamp-on aerodynamic handlebar attachment comprising: a) a pair of hand area elements, b) at least one sliding element, c) means for joining said hand area elements and said sliding element, said means for joining including means to: i) receive and hold one end of said pair of hand area elements with the free ends of each hand area element in symetrical position with respect to each other with said free ends extending outwardly from said means for joining, and ii) receive and hold one end of said sliding element with the free end of said sliding element in spaced relation with respect to said free ends of said pair of hand area elements and directed toward said handlebar of said bicycle, d) at least one adjustable handlebar clamp, said clamp including means for adjustably attaching said clamp to one of said bar portions of said handlebar on one side of said steering post, said handlebar clamp being adapted to slideably receive and adjustably hold said free end of said sliding element, said sliding element being adjustably positioned within said handlebar clamp to determine the forward position of said hand area elements forward of said steering post, e) said hand area elements being arcuately bent from said means for joining said hand area elements and said sliding element to position said free ends of said hand area elements above and directed toward said handlebar when attached, f) said sliding element being arcuately bent along a portion of its length between said handlebar clamp and said means for joining said hand area elements and said sliding element to position said means for joining above the axis of said bar portions of said handlebar, g) said pair of hand area elements, said sliding element and said means for joining being an assembly of said handlebar attachment adapted to be positioned with respect to and clamped on said handlebar with said hand area elements forward of and symetrical to said steering post and positioned with respect to said handlebar end portions and steering post so as to permit a rider of said bicycle to rest the elbows of the rider on said handlebar end portions of said handlebar while grasping said hand area elements with the rider's hands in comfortable normal hand/forearm alignment. 4. The handlebar attachment of claim 3 wherein said arcuate bend of said hand area elements is about 65° from the portion of said element attached to said joint. 5. The handlebar attachment of claim 3 wherein said arcuate bend of said sliding elements is about 37° from the portion of said sliding element attached to said joint. 6. The handlebar attachment of claim 3 wherein said hand area elements and said sliding elements are tubular. 7. The handlebar attachment of claim 3 wherein said joint of said hand area elements and said sliding element is constructed as a unitary element with openings for receiving said hand area elements and said sliding element. 8. The handlebar attachment of claim 3 wherein said joint of said hand area elements and said sliding element is a four way unitary element formed to position said hand area elements and a pair of said sliding elements in a predetermined alignment.
