Sold Out
Chase fast gravel and long adventure days from a more aerodynamic, more comfortable position. The PRO Discover Aero Carbon handlebar pairs a flared, ergonomic shape with a feathery UD T700 carbon layup, so you stay confident on rough terrain without giving up speed on the open road.
Highlights
- Lightweight UD T700 carbon construction with Dyneema for strength where it counts
- 12-degree flare for stable, controlled handling on loose and technical ground
- Compact 100mm drop and 72mm reach for an easy, repeatable transition to the drops
- 4-degree forward sweep that takes pressure off your wrists on long rides
- Internal routing for electronic shift cables and brake hoses keeps the cockpit clean
Built for fast gravel
The flared drops widen your stance for extra leverage and confidence when the surface gets rough, while the aero-shaped tops let you tuck in and cut through the wind on smoother sections. The downsloping shape and compact drop make it natural to ride low for longer.
Light and stiff
A unidirectional T700 carbon layup reinforced with Dyneema keeps weight down to around 265g while delivering the stiffness you want when you are sprinting or hauling on the bars out of a corner.
Clean integration
Internal channels route electronic shift wiring and hydraulic brake hoses inside the bar for a tidy, snag-free cockpit. The bar is also compatible with PRO Compact Carbon clip-on aero extensions if you want to add a time-trial position.
Compatibility & fit
This is the 40cm width with a standard 31.8mm stem clamp diameter, suiting any stem with a 31.8mm bar bore. The internal routing is designed for electronic (Di2-style) shifting and hydraulic disc brake hoses. Intended for drop-bar gravel and road bikes.
