Bullhorn handlebars were born of necessity. A set of drop bars were flipped upside down and then cut off. All base bars since were a riff on that simple solution and little thought went into them. Until now. Spearheaded by the restless Gerard Vroomen, a Cervélo co-founder, the 3T Revo LTD reinvents the base bar.

The easiest way to describe the Revo base bar is a reverse bullhorn. Its 40cm wide, measured center-to-center. The 31.8mm center-section base bar has a forward-sweeping and dipping wing, with a drop of 46mm. But at the ends of the wing, the 83mm long hand rests are behind the wing, rather than in front, giving you a reach of 72mm. This is both for aerodynamics and comfort.

More importantly, you get more security with the wing in front of your hands. There’s no way your hands can slip forward and off, even if the bar is covered in water or sweat. Accelerating, sprinting, descending, cornering on choppy pavement, and your hand will stay put without fear. Adding to both aerodynamics and comfort is the slight triangulation at the back end of the base bar. Easy to grip with your smaller fingers.

Any internal-clamp brake or brake/shift lever will still fit in front of the bar, so you will have the brake lever in an ergonomically comfy position.

Atop the base bar are the mounts for extensions. 335mm long High-modulus carbon-fiber S-bend bars are included in the package, as are 10 and 20mm spacers. Stack height to the armrests can be as little as 30mm and as high as 97mm, depending on how you utilize the stack spacers. The width between the armrests can be as little as 220mm, as measured from outer edge to outer edge, and as wide as 340mm. And the reach of the pads can be set anywhere from 20mm ahead of the base bar center, measuring from the front pad edge, to 70mm. And the pads can be canted for greater comfort.

Total weight, without cutting down the extensions, is as little as 700g, without stack spacers, and as much as 830g. It is UCI-compliant

The 3T Revo LTD aerobar changes the direction of base bars forever.
