SplitStream TriBars / Triathlon Handlebars

During the cycling portion of a triathlon, athletes often switch between two different sets of handlebars depending on the terrain. SplitStream handlebars simplify the process by combining the functionality of separate handlebars into one unit. A hinge mechanism at the center reconfigures the handlebars between a wide configuration for accelerating, decelerating, climbing and turning through corners and a compact, elongated position that optimizes aerodynamics for flats and straightaways. Unlike other triathlon handlebars, the brakes and gears are available when the handlebars are in either position.
