Sold Out
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. UD T700 carbon with Dyneema damps trail buzz to delay fatigue, and a 12-degree flare opens up stability and confident braking over rough terrain.

- UD T700 carbon with Dyneema for vibration damping and a light, durable build
- Internal routing for electronic shift cables and brake hoses for a clean cockpit
- Light 280g claimed weight in this 42cm size
- Compatible with PRO Compact Carbon Clip-On aero extensions
Aero where it counts
The flattened, aero-profiled tops give you a slippery, comfortable position for putting down power on the flats, while the smooth transition into the hoods keeps your hands settled for the long haul. It is a shape tuned for riders who treat gravel as a race, not just a ramble.
Flare and control on rough ground
A 12-degree flare with 4 degrees of forward sweep widens your stance in the drops, where you want maximum leverage and braking confidence on fast, technical descents. The compact 100mm drop and 72mm reach keep the drops within easy reach, so you spend more time in the most controlled position.
Carbon that takes the edge off
The UD T700 carbon layup with Dyneema is engineered to soak up high-frequency vibration from chattery gravel and corrugations, helping delay arm and hand fatigue on big adventures, all while keeping weight low.
Compatibility & fit
Standard 31.8mm clamp diameter to suit the vast majority of gravel and road stems. Width is 42cm measured centre-to-centre at the hoods (also available in 40cm and 44cm). Routes electronic shift cables and brake hoses internally, and works with PRO Compact Carbon Clip-On aero extensions for bikepacking and long-distance positions.
