Fast on gravel, comfortable on long days — the PRO Discover Aero Carbon handlebar is built for riders who refuse to choose between speed and control. Flared compact drops widen your stance on rough terrain while the aerodynamic tops let you tuck in and push pace on smoother sections.

Highlights

  • UD T700 carbon with Dyneema: Lightweight, stiff layup delivers genuine weight savings (265g at 40cm) without sacrificing durability on rough ground.
  • 12-degree flare: Widens your grip in the drops for improved leverage, stability and confidence when the surface gets technical.
  • Compact 100mm drop, 72mm reach: Easy, natural transition to the drops and a riding position that's accessible on long days in the saddle.
  • 4-degree forward sweep: Reduces wrist pressure and fatigue on extended gravel rides.
  • Internal routing: Channels for electronic shift wiring and hydraulic brake hoses keep the cockpit clean and snag-free.
  • Aero-shaped tops: Flat, wide tops encourage an aerodynamic position and give stable placement for long paved sections.

Built for fast gravel

The Discover Aero Carbon is designed around PRO's gravel-specific testing standard — a bar shape that performs from fast open roads to loose, technical singletrack. The downsloping profile and flared drops work together to give you a planted, confident position without forcing you into an aggressive race crouch. Whether you are chasing a gravel stage or piling on kilometres in the hills, the geometry rewards all-day effort.

Light and integrated

The UD T700 carbon layup reinforced with Dyneema keeps weight at 265g for the 40cm variant while providing the stiffness needed when you are sprinting or hauling hard on the bars. Internal channels route Di2-style electronic shift wiring and hydraulic disc brake hoses inside the bar for a tidy finish that also protects cables from trail debris. The bar is also compatible with PRO Compact Carbon Clip-On aero extensions for riders who want a time-trial or triathlon position on the same cockpit.

Compatibility & Fit

This variant is 40cm wide (measured centre-to-centre) with a 31.8mm stem clamp diameter, suiting any stem with a standard 31.8mm bar bore. Internal routing is designed for electronic (Di2-style) groupsets and hydraulic disc brake hose. Intended for drop-bar gravel and adventure road bikes. Compatible with PRO Compact Carbon Clip-On aero extensions.
