PRO Discover Carbon Gravel Handlebar 44cm (31.8mm, 20° Flare)
SKU code: SHM-PRHA0452
Sold Out
Built for fast, confident gravel riding, the PRO Discover Carbon handlebar pairs a generous 20-degree flare with a light, robust UD carbon build, so you get extra control and stability on loose, technical terrain without carrying needless weight. The compact drop and ergonomic tops keep your hands comfortable through long days in the saddle and easy to reach when the trail gets rough.
Highlights
- 20-degree flare opens up the drops for more leverage and control on rough, loose surfaces
- Lightweight, durable UD carbon construction for a stiff, responsive feel
- Compact 110mm drop makes moving in and out of the drops quick and easy
- Ergonomically shaped tops for all-day comfort and secure grip
- Integrated cable routing keeps the cockpit tidy
- 44cm width with a 31.8mm stem clamp
Control where it counts
The 20-degree flare angles the drops outward, widening your grip and giving you more stability and braking leverage when you are descending or riding washboard gravel. The compact drop shape means the transition from tops to hoods to drops stays natural and within easy reach.
Light and comfortable
UD carbon keeps the bar light while staying stiff under load, and the flattened, ergonomically shaped top section spreads pressure across your palms to reduce fatigue on long rides.
Tidy cockpit
Integrated routing carries both Shimano Di2 wires and mechanical cables through the bar for a clean, snag-free front end. There is room above the bar clamp for an upper brake lever such as Shimano GRX.
