Introducing the GB Series: New 9Velo Gravel Wheels is Available with Berd PolyLight Spokes

The new 9Velo GB Series gravel wheels are available with advanced Berd PolyLight spokes, a revolutionary and unique option for riders seeking ultra-lightweight performance, enhanced comfort, and a standout look. Featuring Berd polymer spokes for vibration damping and weight savings, a 28mm internal wide rim profile for modern gravel tires, and a hub system designed for easy builds and long-term reliability, the GB Series is the ultimate gravel wheelset.

What Are Berd Spokes?

Berd spokes are crafted from an advanced polymer called ultra-high molecular weight polyethylene (UHMWPE)—a material that boasts 15 times the strength-to-weight ratio of steel and can float on water. This fiber is used in aerospace, medical, and military applications, and Berd brings them to the cycling world with stunning results.

Unlike traditional steel spokes, Berd spokes are soft to the touch yet incredibly strong. According to Berd, they offer improved fatigue life, are impervious to the elements, and maintain consistent performance in all weather conditions.

Advantages of Berd Spokes: More Than Just Light

Berd Polylight spokes are up to 50% lighter than steel spokes. Compared to the traditional premium steel spokes, such as Sapim CX-Ray, Berd spokes save approximately 43% of the spoke weight, offering featherweight climbing performance and improving acceleration.

Another advantage is its vibration ability. Their flexible nature absorbs road chatter, enhancing comfort on rough terrain, which is suitable for gravel riding and MTB riding. 

In fact, Berd spokes have earned their place at the pinnacle of competitive cycling. At the Paris 2024 Olympic Games, Tom Pidcock of Great Britain clinched gold on the demanding course in the Men's Cross-Country Mountain Bike event, riding on wheels laced with Berd’s revolutionary PolyLight UHMWPE spokes. Pauline Ferrand-Prévot also took gold in the women’s event using the wheels laced with Berd Polymer spokes.

Made from UHMWPE, Berd spokes are rust-proof and built for long-lasting performance. Their thin profile contributes to improved aerodynamics, and the polymer material contributes to a quiet ride. Moreover, their unique look turns heads on any terrain.
