VoiceVelo VFV ADV Carbon Stem

Integration, Done Properly.

The VoiceVelo VFV ADV Carbon Stem is a lightweight, fully integrated carbon stem designed for modern road and gravel bikes where clean internal cable routing, low weight and dependable performance matter.

Constructed from unidirectional carbon fibre, the VFV ADV combines a full carbon stem body, carbon faceplate and integrated carbon top cap with premium S-Parts titanium hardware.

Designed around fully internal routing and available in a wide range of lengths, the VFV ADV provides a clean and highly refined cockpit solution for both VoiceVelo framesets and compatible custom builds.

Full Carbon Construction

The VFV ADV is designed around carbon from the outset, with the material used throughout the primary structure rather than simply as a cosmetic or weight-saving addition.

The stem features a unidirectional carbon fibre body, full carbon faceplate and carbon top cap, creating a lightweight structure engineered to provide the stiffness and control required for demanding road and gravel riding.

With weights starting from approximately 120g, the ADV achieves its low weight without resorting to an excessively minimalist design.

Fully Integrated Internal Cable Routing

The VFV ADV has been specifically designed to accommodate fully internal cable routing.

Internal pathways through the stem allow brake hoses and cables to pass cleanly through the cockpit and into a compatible headset and frame, eliminating exposed routing around the front of the bike.

When paired with the VoiceVelo G Gravel Flared Carbon Handlebar, the system provides a clean route through the handlebar and stem for a highly integrated front end.

Designed to Work as a System

The VFV ADV is designed to integrate particularly cleanly with the:

VoiceVelo ECHO Frameset
VoiceVelo G-Major Frameset
VoiceVelo G Gravel Flared Carbon Handlebar

The combination creates a streamlined cockpit with internal routing while retaining a separate handlebar and stem configuration, providing greater flexibility when selecting or changing cockpit dimensions than a one-piece integrated cockpit.

S-Parts Titanium Hardware

Premium S-Parts titanium bolts are supplied as standard.

The lightweight titanium hardware complements the carbon construction while providing a high-quality finishing detail throughout the cockpit.

No additional hardware upgrade is required.
