The PRO Vibe Superlight is PRO's lightest forged alloy road stem — built for riders who want every gram accounted for without sacrificing the stiffness that keeps steering sharp under power. Forged 7075 alloy combined with titanium Torx hardware delivers a race-ready cockpit anchor that works equally well on modern integrated road bikes or traditional builds.

Highlights

• Forged 7075 alloy: PRO's go-to lightweight alloy for high-strength stems that resist flex and hold torque specs reliably.
• Titanium Torx hardware: Saves weight over steel bolts and resists corrosion — the finish stays clean through thousands of kilometres.
• ±6° flip-flop design: Flip the stem to switch between a +6° (more upright) or −6° (more aggressive) position without swapping parts.
• Di2 integration: Designed to work with SHIMANO Di2 electronic groupsets — wiring runs cleanly through the stem.
• Versatile cable routing: Supports fully integrated, partially integrated, and classic cable routing to suit your frame.
• 38mm stack height: Low-profile steerer clamp keeps spacer stacks compact for a clean cockpit.
• Pairs with PRO Vibe Superlight: Designed as a matched system with the PRO Vibe Superlight handlebar for optimum stiffness and aesthetics.

Light where it matters

Forging 7075 alloy (rather than casting or extruding) produces a denser grain structure and higher strength-to-weight ratio. That means PRO can remove material where it isn't needed while keeping wall thickness exactly where the load is highest — at the steerer clamp and handlebar clamp faces. Titanium Torx faceplate and steerer bolts complete the weight-saving approach without any compromise to clamping security.

Ready for the modern road bike

The Vibe Superlight accommodates fully integrated, partially integrated, and classic cable routing, so it works across a wide range of road and endurance frames. Di2 junction wiring passes through cleanly, keeping the cockpit free of cable clutter. The 38mm steerer stack height keeps the stem compact, helping riders running minimal spacers achieve a truly low front end.
