If you had to choose just one wheel, the 404 Firecrest should be your choice. With the depth and shape proven in all conditions it's the all-around performer and standard by which all aero wheels are measured. At the center of the wheelset is Zipp's 77/177 hubset, an innovation that results in improved stiffness, durability, simplicity and versatility
- Firecrest rim technology affords the rider more speed, more stability, and more strength. This technology offers stable, predictable handling, and the wider rim increases lateral stiffness while offering greater vertical compliance
- Each wheel includes Zipp quick release skewer, end caps that can be swapped to run 12mm or 15mm thru axle; 1 Zipp 700c X 20mm rim tape, and 1 Zipp tubeless valve
Going tubeless allows you to run lower tire pressures without the added weight of a tube. Lower tire pressure has many benefits, including greater traction, lower rolling resistance over rough surfaces, and decreased risk of a puncture-related flat.
Tubeless-ready rims and tires are parts of a complete system that eliminate the need for tubes by creating an airtight chamber between the rim and tire. Liquid sealant is added to the chamber to fill small punctures and maintain air pressure while you ride.
UST (Universal Standard for Tubeless) is a specific type of tubeless system that dictates the shape of the rim and tire bead. UST rims should be paired with UST-specific tires for best results.
