Built for full-gas gravel racing and long days in the saddle, the PRO Discover Aero Carbon Handlebar blends an aerodynamic top section with flared, compact drops so you can go faster while staying comfortable and in control on rough terrain. UD T700 carbon reinforced with Dyneema damps trail vibration to delay arm fatigue, and a 12-degree flare opens up stability and confident braking on loose surfaces.

Highlights

• Aero top section: flattened and approximately 40mm deep, cuts through headwinds and rewards an aerodynamic position on the flats.
• 12° flare with 4° forward sweep: widens your stance in the drops for a stable, confident grip and maximum braking leverage on rough descents.
• Compact geometry: 100mm drop and 72mm reach make it easy to transition between hand positions and stay in the drops longer.
• UD T700 carbon with Dyneema: optimised layup filters high-frequency gravel chatter while keeping the bar light at a claimed 280g.
• Internal cable routing: externally accessible grooves route electronic shift cables and brake hoses cleanly, with dedicated Di2 controller ports.
• Clip-on compatible: 31.8mm clamp diameter works with PRO Compact Carbon Clip-On aero extensions.
• 4° downward slope on tops: naturally supports a neutral hand position for long-distance comfort when riding on the hoods.

Aero where it counts

The flattened, deep-section tops create a slippery silhouette into headwinds and give your hands a firm, ergonomic platform for sustained power on gravel straights. A smooth transition through the hoods keeps your position settled over rough terrain — this is a bar shaped for riders who treat gravel as a race.

Flare and control on rough ground

The 12-degree drop flare combined with a 4-degree forward sweep broadens your stance in the drops, increasing leverage for confident braking on fast, technical descents. The compact 100mm drop and 72mm reach keep the drops easily accessible, so you spend more time in the most controlled position on the bike.

Carbon construction with Dyneema damping

The UD T700 carbon layup woven with Dyneema fibres is engineered to soak up high-frequency vibration from chattery gravel and corrugations. The result is a handlebar that is both stiff enough to sprint from and compliant enough to ride all day — at a claimed weight of 280g in the 42cm width.

Compatibility & fit

Standard 31.8mm clamp diameter suits the vast majority of gravel and road stems. Width is 42cm measured centre-to-centre at the hoods. Also available in 40cm and 44cm. Internal routing channels are externally accessible for easy cable installation; Di2 controller ports are pre-drilled for electronic drivetrains. Works with PRO Compact Carbon Clip-On aero extensions.
