The PRO Vibe Superlight is PRO's lightest road stem, shaving precious grams off the front end without giving up the stiffness you want when you're out of the saddle. At 120mm it suits riders chasing a longer, stretched-out position for a sharp, performance-focused fit on road or triathlon builds.

Highlights

• PRO's lightest road stem: forged 7075 alloy body and titanium Torx hardware combine for an exceptionally low-weight cockpit upgrade.
• 120mm length: suits riders targeting a longer reach for a more aggressive, aerodynamic road position.
• 31.8mm bar clamp: fits the vast majority of modern road handlebars including PRO's own Vibe Superlight bar.
• 1 1/8" steerer fitment: compatible with standard threadless forks across road and endurance bikes.
• Reversible +/-6 degree angle: flip the stem to run it with rise or slammed to fine-tune bar height without swapping parts.
• Di2 and cable-routing ready: optimised for Shimano Di2 integration and compatible with internal, semi-internal, and traditional cable routing.

Light where it counts

Forged from 7075 alloy — the same high-strength aluminium alloy used in premium cockpit components — the Vibe Superlight keeps weight down where it's most noticeable. Titanium Torx bolts replace standard steel hardware to trim additional grams without compromising clamping security. At 118g for the 120mm length, it's a meaningful upgrade over a standard alloy stem.

Clean, integrated cockpit

The Vibe Superlight is designed to pair seamlessly with the PRO Vibe Superlight Handlebar, and it's built with internal cable management in mind. Di2 wiring and brake/shift cables can be routed cleanly through compatible frames and bars, keeping the front end tidy and aerodynamic. It works equally well with traditional external cable routing setups.

Dial in your fit

The reversible +/-6 degree angle gives you two stack height options without needing to purchase a different stem. Run it positive for a touch more bar height on longer rides, or flip it to negative for a slammed, race-ready position. Combined with the 120mm reach, it targets riders who want a low, extended road fit.
