Their PolyLight™ spokes are the lightest spokes in the world. They have a unique vibration dampening property and allow cyclists to ride farther and faster with less effort. Wheels built with Berd spokes outperform steel spokes when exposed to impact. This is because Berd spokes distribute the energy of the impact over more spokes, which puts less stress on the rim, spokes, hub and nipples. Berd spokes also excel in torque fatigue due to the material properties of Dyneema®. They have proven themselves at the highest level: Berd spokes were used in the wheels of the Olympic gold medal winners in Cross Country for both men and women (Pidcock & Ferrand-Prévot) WORLD'S LIGHTEST BICYCLE SPOKES
