Zipp 3ZERO MOTO B1 Rear Wheel

Unlike traditional box-section rims that are rigid, the single-wall construction allows the rim to flex laterally. This helps the wheel track better over rough, uneven terrain, which improves traction and reduces rider fatigue on long, technical descents.

The 3ZERO MOTO B1 is designed for modern trail and enduro bikes. It features 148mm Boost hub spacing, a 12mm thru-axle, and a SRAM XD cassette body, so ensure your frame and drivetrain are compatible with these standards before purchasing.

The hub features 132 points of engagement, which provides nearly instantaneous power transfer. This is particularly useful on technical climbs where you need to ratchet your pedals over obstacles without losing momentum.

While the wheel is optimized for a tubeless-ready setup to maximize the benefits of the rim's flex and traction, it is compatible with inner tubes if you prefer that configuration.

The 30mm internal width is ideal for high-volume trail and enduro tires, typically ranging from 2.3 to 2.6 inches. This width provides a stable platform that prevents tire squirm during aggressive cornering.

Not at all. The single-wall design is specifically engineered for impact resistance. By allowing the rim to flex slightly under load, it actually helps absorb impacts that might otherwise crack a stiffer, traditional carbon rim.
