Fulcrum Racing Zero Wheel

This wheel features 2-Way Fit technology, meaning it is fully compatible with both standard clincher tires with inner tubes and tubeless-ready setups. The 19mm internal rim width is optimized for modern road tires, providing a stable platform for various widths.

CULT (Ceramic Ultimate Level Technology) bearings use ceramic balls and special steel races that are significantly smoother and more durable than standard steel bearings. They require less maintenance and offer noticeably lower rolling resistance, which helps maintain speed more efficiently.

The hub is compatible with Shimano HG11 and Sram XDR standards. Please ensure your current cassette matches one of these configurations before purchasing.

The 2:1 spoke ratio is specifically engineered for disc brakes. By using twice as many spokes on the side subjected to the most torque and braking stress, the wheel maintains better structural integrity and power transfer compared to a traditional 1:1 lacing pattern.

This rear wheel is designed for a 142 x 12mm thru-axle standard, which is the most common specification for modern disc-brake road bikes. Always verify your frame's axle spacing before installation.

Yes, the 30mm profile strikes a balance between aerodynamics and handling. It offers a slight aero advantage over a box-section rim while remaining stable and predictable in crosswinds, making it an excellent choice for climbing and varied terrain.
