The PRO Vibe Stem 1 1/4 gives your road cockpit a clean, race-ready front end with a tidy integrated look and the stiffness you want when you put the power down. Forged 7075 alloy keeps weight in check while the wide 1 1/4-inch steerer clamp delivers confident, precise steering, and the Shimano Di2 integration tucks your wiring and junction neatly out of sight.

Highlights

  • Stiff, precise front end built for road riding and racing
  • Anodised 7075 aluminium construction for a strong, lightweight build
  • 1 1/4-inch steerer clamp for direct, confident steering
  • 31.8 mm handlebar clamp suits the most common road bars
  • Shimano Di2 integration with an integrated top cap for a clean cockpit
  • Lightweight titanium hardware

Stiff and light

Forged from anodised AL 7075 aluminium, the Vibe stem balances low weight with the rigidity that keeps your steering sharp and your sprints efficient. Titanium bolts trim grams without giving up clamping security.

Clean Di2 integration

An integrated top cap and Shimano Di2 integration let you route and house your electronic shifting hardware neatly, keeping the front of your bike uncluttered and tidy.

Compatibility & fit

This stem is designed for a 1 1/4-inch fork steerer and clamps 31.8 mm diameter handlebars. It measures 80 mm long with a -10 degree angle. It is compatible with the PRO Stem Computer Mount (PRAC0247), which bolts to the forward stem bolts. Confirm your fork steerer is 1 1/4 inch and your handlebar is 31.8 mm before fitting.
