Built for gravel racing and big mixed-surface days, the PRO Discover 12 Alloy handlebar gives you confident control on loose descents and an efficient, aggressive position when the going gets fast. Its 12-degree flare widens your stance in the drops for better leverage off-road, while a compact 70mm reach and 110mm drop keep the bar comfortable and quick to reach all day.

Highlights

  • Stable, controlled handling on rough terrain thanks to a 12-degree flared drop
  • Aggressive yet comfortable fit with a medium 70mm reach and 110mm drop
  • Lightweight, durable AL-6066 aluminium construction (from 286g)
  • Aerodynamically shaped top section for a faster, more efficient front end
  • Clean cabling via a routing groove along the bar
  • Works with both wired and wireless electronic and mechanical groupsets

Control where it counts

The 12-degree flare angles the drops outward, widening your grip exactly where you want stability and braking leverage on rough, loose ground. The compact shape keeps the transition from hoods to drops short, so you can move between hand positions quickly when the terrain changes.

Fast on the flats

An aerodynamically optimised top section helps you cut a cleaner line into the wind, while a routing groove keeps cables and hoses tidy for a neat, aggressive cockpit.

Light and tough

High-performance AL-6066 aluminium balances stiffness, durability and low weight, making this a dependable choice for race days and long adventures alike.
