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:
- 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
STIFFNESS: PERCEPTION VS. REALITY.
While other wheel brands limit their focus to traditional box-section rim designs, Zipp engineers—uninhibited by legacy technology—wiped the white board clean. All the best ideas eventually pointed to motorsports inspiration and Moto Technology’s single-wall rim the optimal approach for an enduro/trail wheelset.
The 3ZERO MOTO’s stiffness, compliance and durability comes from Zipp’s proprietary process to design and assemble rim, hub, and spokes. Each 3ZERO MOTO wheel is built as a system, its ZM1 hubset and 32 spokes and handmade carbon rim all integrate to play key roles in performance. Look at a cross section of the 3ZERO MOTO and you can see the difference right away. It’s a quantum jump from the typical and limiting box-section design that bicycle wheels have always used – our moto-inspired design allows the fastest trail riders on earth to fly over the roughest terrain imaginable with speed and control like never before. Allow us to explain:
Lateral stiffness – In a sharp turn, the rim remains stiff, providing confidence that the wheel is firmly planted. Zipp’s wide hub flanges provide better spoke-bracing angles which help to increase the lateral stiffness.
Torsional windup – When torque is applied to the rear hub when pedaling, you don’t want the spokes to create a spring-like flex sapping your wattage. Having 32 spokes at the right tensions keep the wheel constrained during windup, meaning the energy in your legs is efficiently transferred to your rear wheel.
Radial Compliance – When you hit a rock, the systems is designed to act as a shock absorber. Zipp’s MOTO Technology allows the rim to flex, which absorbs the impact energy and spreads it away from the impact zone for increased durability. In essence, more of the rim carries the load from the impact.
“Ankle” Compliance – Image a runner rounding a sharp turn, the ankle naturally flexing to maintain grip as the runner leans. The rim can locally flex to stay parallel to the ground during cornering, which increases traction much like a human ankle. This ability to twist locally allows it to deflect during single bead impacts without the rider getting bounced off line.
Durability and ride quality – 3ZERO MOTO rim strength exceeded our expectations for impact resistance due to MOTO technology compliance. As for ride quality, the wheel also deflected three times more than top rival box-section carbon wheels. That extra compliance behaves like extra suspension, but it also spreads the impact energy over a larger area. This also benefits the rider in the form of pinch flat prevention.
The benefits of all that are simple. More control. Fewer line deviations. Greater durability. Fewer pinch flats. The net gain? Pure speed.
