FSA’s Groundbreaking Innovation: 360-Degree Handlebar Isolation with NS VAS STEM

Vibration damping for enhanced riding

In the wide-open world of cycling, where man and machine meld into a single, wind-slicing entity, few innovations have the power to truly shift the balance of power. Yet, I stand before a game-changer, the NS VAS STEM, a piece of tech that promises to redefine how we engage with the relentless terrain beneath us.

A creation from the house of FSA, this stem is a pioneer, a trailblazer. This isn't just a component – it's a revolution for AGX and MTB applications alike. What sets this piece apart is its ingenious application of 360-degree handlebar isolation, a bold stroke of engineering brilliance that seeks to combat vibration like none other before it.

You see, the crux of off-road biking, the allure and the curse, lies in the raw, untamed surfaces that we pit ourselves against. While it's this ruggedness that pumps adrenaline through our veins, it's also what sends shuddering impacts up our arms, leading to what we bikers dread – arm pump and hand fatigue. The FSA NS VAS STEM, with its vibration damping prowess, seeks to challenge this very problem. By reducing the forces we often contend with, it's like a balm for our weary limbs, promising us not just a better ride but also shorter recovery periods.

Beyond its technical brilliance, this stem demonstrates a keen eye for detail and customization. With three different lengths available and a Ø31.8mm handlebar clamp diameter, it offers the perfect fit for every rider. And those three color bushing options? They're not just about aesthetics. Each color corresponds to a different hardness level, allowing riders to choose according to their comfort or performance needs.

The lighter grey speaks comfort, dark grey indicates a sporty setting, and the darkest black is meant for the racers among us. At a mere 291 grams (for the Ø31.8x100mm), this stem is lightweight but certainly not light on its features or potential impact.

However, it's worth noting that the NS VAS Stem has its restrictions too. It's not compatible with handlebars that have holes for cable routing in the central clamping region. So be sure to verify your handlebars before installation.

What's evident is that this innovative stem, much like a carefully crafted poem, speaks to the heart of biking – balance, resilience, and unyielding pursuit of better. A testament to where the world of cycling technology is headed, the FSA NS VAS STEM is more than an addition to your bike. It's an upgrade to your biking experience. It's the kind of investment that pays off in smoother rides and fewer aches, allowing you to chase the horizon that much longer.

Without a doubt, the NS VAS STEM has a lot to offer for cycling enthusiasts. Let's dig into the pros and cons to get a better understanding.


  1. Innovative Design: The NS VAS STEM is the first to feature vibration damping through 360-degree handlebar isolation. This design is aimed at reducing forces and impacts to your hands and arms, reducing arm pump and hand fatigue.
  2. Customization: It comes in three different lengths, which means you have more options to choose the stem that fits your bike and riding style. The three bushing color options correspond to different hardness levels (70A, 80A, 90A), offering choices for comfort, sport, and race applications.
  3. Lightweight: The stem weighs just 291 grams (for Ø31.8x100mm), which is fairly light for such a feature-packed stem, ensuring it doesn't add significant weight to your ride.
  4. Versatile Applications: The stem is suitable for both AGX and MTB applications, making it a versatile choice for various riding styles and terrains.


  1. Compatibility Issues: The NS VAS Stem is not compatible with handlebars that have holes for cable routing in the central clamping region. This could be a drawback for some riders who use such handlebars.
  2. Price: At $182, the NS VAS STEM is quite an investment. While the advanced features may justify the cost for some, it might be out of reach for others, especially casual riders or those on a tight budget.
  3. Unverified Claims: While the vibration-absorbing technology sounds promising, it's a relatively new concept. Until it's tested extensively by riders in various conditions, it's hard to conclusively say how effective this technology will be.

In conclusion, while the NS VAS STEM has some fantastic features and innovative design elements, it's crucial to consider these pros and cons before deciding if it's the right fit for your riding needs and budget.
