Sharpen your riding position with the PRO Vibe Stem, a stiff, race-bred alloy stem that puts your front end exactly where you want it. The 90mm length and -10 degree angle drop you into a lower, more aerodynamic stance, while the clean integrated topcap keeps the cockpit looking purposeful and tidy.

Highlights

  • Lower, more aggressive riding position from the -10 degree angle
  • Stiff, precise steering response thanks to forged 7075 alloy
  • Lightweight titanium hardware trims grams without sacrificing strength
  • Tidy, integrated topcap for a clean cockpit finish
  • Fits standard 31.8mm road handlebars

Built for performance

Constructed from anodised AL 7075 alloy, the Vibe Stem delivers the rigidity serious road riders rely on for sprints, climbs and hard cornering. Power and steering inputs transfer directly to the front wheel with minimal flex.

Light, clean hardware

Lightweight titanium bolts keep weight down while holding the bar and steerer securely. The integrated topcap finishes the headset neatly and removes clutter from the top of the cockpit.
