The PRO Vibe Carbon Stem delivers a lightweight, aerodynamically refined front end for road cyclists who want a clean, integrated cockpit. Built from T700 unidirectional carbon with titanium bolts and an aluminium faceplate, it pairs well with the PRO Vibe handlebar to create a cohesive, performance-focused cockpit.

Highlights

• T700 UD carbon body: full carbon construction keeps weight to a minimum while maintaining torsional stiffness for direct, precise steering.
• Puzzle Clamp system: the evolved four-bolt faceplate distributes clamping force evenly across the handlebar, reducing pressure points and protecting carbon bars.
• Flip-flop design: +/-8° angle means a single stem can be run with a rise or a drop to fine-tune your riding position without buying a new stem.
• Aerodynamically optimised profile: the shaped body streamlines the front of the bike for a cleaner look and marginally reduced drag.
• Shimano Di2 compatible: internal cable routing accommodates Di2 electronic shifting wiring for a tidy, integrated cockpit build.
• Titanium bolts: four titanium faceplate bolts save grams while maintaining clamping integrity.
• Designed for the PRO Vibe cockpit: pairs perfectly with PRO Vibe handlebars for a matched, integrated front end.

T700 carbon construction

The stem body is formed from T700 unidirectional carbon fibre — the same grade found in high-end road frames. This gives the Vibe Carbon Stem an excellent stiffness-to-weight ratio, translating sprint and climbing efforts into forward motion rather than flex. The aluminium faceplate and titanium bolts complement the carbon body without adding unnecessary mass.

Puzzle Clamp system

PRO's Puzzle Clamp design uses a shaped faceplate that meshes precisely with the stem body to spread clamping load evenly. This is particularly important when used with carbon handlebars, where uneven bolt tension can cause localised stress. The four-bolt pattern allows consistent, incremental torquing to spec.

Compatibility & Fit

This stem fits a standard 1-1/8" (28.6mm) steerer tube and a 31.8mm handlebar clamp diameter. The flip-flop design gives a +8° or -8° angle depending on orientation. Stack height is 35mm. This listing is the 90mm length in Black; the PRO Vibe Carbon Stem is also available in 80, 100, 110, 120, and 130mm lengths. Shimano Di2 cable routing is supported. Supplied with four titanium faceplate bolts.
