The PRO Vibe Superlight stem is PRO's lightest road stem, combining forged 7075 alloy construction with titanium Torx hardware for a stiff, reliable cockpit with minimal weight. Designed for road cyclists chasing a clean, performance-focused front end, it pairs natively with the PRO Vibe Superlight handlebar and supports Shimano Di2 integration with internal, semi-internal and traditional cable routing.

Highlights

• 7075 alloy forging: High stiffness-to-weight ratio keeps steering sharp without adding grams.
• Titanium Torx hardware: Saves weight over steel bolts and resists corrosion in all conditions.
• Versatile +/-6 degree angle: Flip the stem to raise or lower the bars without changing stem length.
• Di2 ready: Optimised for Shimano Di2 integration and compatible with internal and semi-internal cable routing.
• Cockpit system compatibility: Designed to work with the PRO Vibe Superlight handlebar, PRO Vibe Computer Mount, and PRO Gap Cap Expander Carbon.

Light and stiff

Forged from 7075 alloy — the same grade used in high-end road and race components — the Vibe Superlight delivers direct steering feel and confidence on climbs, sprints and technical descents. At 103g for the 90mm version, it is one of the lightest alloy stems available for a standard 31.8mm bar clamp.

Clean integration

The Vibe Superlight is engineered as part of the PRO Vibe Superlight cockpit system. Internal and semi-internal cable routing options keep bar tops clean and wires tidy, while full Di2 integration means electronic groupsets route neatly through the stem for a factory-finished appearance.
