The Deda Tribar Basebar is a carbon one-piece aero bar built specifically for time trial and triathlon racing — a clean, UCI-compliant platform that handles both hand position and extension mounting in a single unit. The wing-profile center section meets the 3:1 UCI ratio and carries ITU triathlon approval, so it's ready for competition out of the box. The geometry is straightforward and purposeful. A 130mm-wide, 31.7mm center section gives your stem and aero extensions a secure clamping surface, while the bar transitions outward into flat hand rests designed for starts, slow-speed handling, and turns. At 42cm outside-to-outside with no drop and a 145mm reach, the fit equation is simple. Full internal routing for electronic groupsets keeps cables out of the airstream, and at 210g the bar adds little to the overall build.
