Zipp 404 Firecrest Tubeless Disc Wheels

If you had to choose just one wheel, the 404 Firecrest should be your choice, in Carbon Clincher or Tubular. 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
Front 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
Rear wheel includes Zipp quick release skewer, end caps that can be swapped to run 12mm x 135 or 142mm thru axle; 1 Zipp 700c X 20mm rim tape, 1 Zipp tubeless valve and 1.85mm spacer for use with 10-speed cassettes
