A stiff, race-ready cockpit upgrade, the PRO Vibe stem delivers precise front-end control and clean cable routing without the weight penalty of a flexy alloy stem. Cold-forged AL 7075 keeps it light and rigid, while Di2 integration tidies your wiring for a pro-level finish.

Highlights

  • Stiff, confidence-inspiring steering for sprints, climbs and fast descents
  • Light AL 7075 alloy construction with titanium bolts to trim grams
  • Shimano Di2 integration keeps junction wiring hidden and tidy
  • Integrated top cap for a clean, uncluttered look
  • -17 degree angle drops the bars for an aggressive, aero position

Built for performance

The Vibe is cold-forged from anodised AL 7075 alloy, the same high-strength material used on premium race cockpits. The result is a stem that resists flex under hard efforts so your steering input goes straight to the front wheel, paired with lightweight titanium hardware to keep overall weight down.

Clean Di2 integration

Designed with Shimano Di2 integration in mind, the Vibe routes electronic wiring neatly through the cockpit and pairs with an integrated top cap for a finished, professional appearance.
