The PRO Vibe Carbon Compact is a purpose-built road handlebar for riders who want to ride longer in the drops without sacrificing control. Its compact bend — 130mm drop and 80mm reach — puts the lower position within comfortable range for riders with smaller hands or less flexibility, while the stiff UD carbon construction keeps every steering and braking input sharp and direct. Integrated cable routing tidies up the front end and makes this bar a natural fit for Shimano Di2 electronic builds.

Highlights

  • Lightweight UD carbon: unidirectional carbon fibre construction keeps weight low while delivering a stiff, responsive feel under braking and sprinting loads.
  • Compact geometry: 130mm drop and 80mm reach bring the drops closer, making the lower position accessible for more riders without requiring extreme flexibility.
  • Integrated cable routing: brake and shift cables route along the bar for a clean, snag-free cockpit and neater builds with both mechanical and electronic groupsets.
  • Shimano Di2 compatible: internal wire routing accommodates Shimano Di2 electronic shifting for a streamlined, cable-free finish.
  • Round top section: comfortable to hold across long days in the saddle and easy to mount lights, computers and accessories.
  • Standard 31.8mm clamp: fits the vast majority of road and gravel stems without adaptors.

Compact geometry that keeps you in the drops

The distance between the tops and the drops is where many riders lose confidence. The PRO Vibe Carbon Compact closes that gap with a 130mm drop and 80mm reach — shorter than a standard anatomic bar — so you can maintain a strong, controlled position when braking hard into corners or pushing pace on a long descent. It pairs particularly well with Shimano short-reach road shifters.

Stiff, light UD carbon

Unidirectional (UD) carbon fibre aligns the fibres in the direction of load for maximum stiffness per gram. The result is a bar that transmits road feel faithfully and resists twist and flex under hard efforts, giving you confidence that your inputs are going exactly where you intend.
