Zipp 404 Firecrest Tubeless Disc Brake Road Wheel Description:

The Zipp 404 Firecrest Tubeless Disc Brake Road Wheel is designed for anyone looking for a lightweight and aerodynamic wheel that is versatile enough to be used for any road racing discipline. At the center of the wheel is a German-engineered ZR1 disc brake hub that is packed with high performance stainless steel bearings that provide very low rolling resistance while also being well-sealed from the elements, and the rear wheel has a robust 6-pawl driving mechanism with 66 points of engagement that will turn each pedal stroke into rapid forward propulsion. Connecting these hubs to the rest of the wheel are premium Sapim CX-Sprint bladed stainless steel spokes that help the wheel to slice through the air and aid in creating a wheel with an ideal balance of stiffness, stability, and a comfortable ride.

While the center of the 404 Firecrest wheel deserves honorable mention, the rim is where these wheels truly shine. This rim utilizes a special unidirectional carbon fiber construction for reduced rotating weight and impressive impact strength, and the outside is covered in a unique ABLC dimple pattern that slides through the air so easily that the reduction in aero drag can be felt and measured in real world riding conditions; those dimples also add considerable stability to the bike when encountering a crosswind by directing the airflow to go around the rim instead of stopping the wind. A 23mm inner rim width with a hookless sidewall design provides outstanding support and stability for modern large volume road tires, and the larger air volume produced by this wide inner rim channel and larger tires will provide a smooth ride and incredible traction especially through corners and over irregular surfaces. The integration of all of these impressive components and features together results in a strong and versatile wheel that is ready to attack race courses everywhere.

Notes: The max recommended system weight of these wheels (weight of the bicycle, rider, and anything else on the bike when riding) is 253lbs (115 KG). The minimum recommended tire width is 28 and the max is 35mm; the aerodynamics are optimized for 28-32mm wide tires.

Features:

• 404 Firecrest hookless, tubeless ready rims have a unidirectional carbon fiber layup that creates a rim with excellent impact strength and low rotating weight
• ABLC Technology uses a complex dimpling pattern to improve the rate that air flows over the rim’s surface and will improve the wheels cross wind stability
• 23mm internal width combined with hookless bead profile provides ideal support for wider tires and allows lower pressures to be safely run for improved traction and a smoother ride
• ZR1 DB was engineered in Germany with better sealing and 66 points of engagement in the rear wheel for very quick power transfer, enhanced durability, and less rolling resistance
• Sapim CX-Sprint spokes improve the durability, comfort, and provide excellent power transfer from the hub that results in very snappy acceleration without wind up
• Hub accepts a centerlock style disc rotor for reliable and consistent braking power, and will include the disc rotor lockring
