Based in the racing hotbed of Indy, Zipp for more than three decades has used motorsports as an inspiration to develop pioneering carbon cycling innovations. Our single-wall approach, what we call Moto Technology™, allows the rims to “pivot” from either side of the spoke bed while traversing rough terrain. As the wheel encounters obstacles, each edge of the rim is designed for compliance, creating the feel of extra suspension.
