Zipp's 3ZERO MOTO carbon rims are inspired by moto to provide riders with the control and durability required for pure speed. Moto remains a powerful source of inspiration for good reason. 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. For the rider, that means durability and control for greater speed. Moto Inspired. Control + Durability = Speed. - Higher impact resistance - Reduced chance of pinch flatting - More traction in rough corners - Smoother ride in rocky terrain - Ability to run lower tire pressure - Reduced rider fatigue - TyreWiz tire-pressure monitoring device - Frustration-free tire installation - Rim is designed for compliance, creating the feel of extra suspension

We’ve narrowed the spoke bed to reduce weight, and we’ve utilized a large, reinforced rim wall edge to withstand impacts related to running low pressures. Thanks to our convex rim profile designed to roll right through sand and snow, paired with our double-wall construction, all-season riding is within reach.
