FSA VAS Stem

The stem uses a specialized elastomer insert that sits between the handlebar clamp and the stem body. This creates a small amount of movement that absorbs high-frequency vibrations and road chatter before they reach your hands, effectively isolating you from rough surfaces.

Yes. The stem includes three different elastomer bushings—comfort, sport, and race—which allow you to customize the feel. You can swap these out to increase or decrease the amount of compliance based on your terrain or personal preference.

This stem is designed for a standard 28.6mm (1 1/8 inch) steerer tube and a 31.8mm handlebar clamp diameter. As long as your bike uses these industry-standard sizes, it will be compatible.

Not at all. While the elastomer system dampens road buzz, the cold-forged alloy faceplate and robust construction maintain a solid, precise connection between your cockpit and the fork. You will feel the benefit of reduced fatigue without sacrificing handling confidence.

While it is optimized for gravel, it is a great upgrade for any road bike if you struggle with hand numbness or fatigue on long rides. The vibration-damping benefits are noticeable on any rough or chip-seal pavement.

At 291 grams, this stem is heavier than a traditional, rigid aluminum stem. However, the added weight is a trade-off for the integrated comfort technology, which is often worth it for long-distance riders looking to reduce fatigue.
