Bullhorn (or pursuit) handlebars, as shown on this @statebicycleco steed, curve up and forward. They are often paired with dedicated clip-on aero bars when used on the road, and are also popular by themselves on track, single-speed, and fixed-gear bicycles.
This style of handlebar is named after the discipline of track racing where it was originally used, and has the common nickname of “Bullhorn bars” for their appearance.
Improvised bullhorn bars may be constructed simply by cutting the drops off drop bars and then mounting them upside down so that the remaining start of the drop provides a slight upward hook for resting the hands, although this does not provide as much forward extension (reach) or lowering (if desired, normally for time-trial based use) as purpose made bullhorns. These are sometimes called “Flopped and Chopped” or “Flipped and Clipped” bars, and if this is to be done, care should be taken to properly remove the sharp edges from the cuts, and to properly tape and plug the bar ends for safety purposes.
