Zipp 404 Firecrest Disc Brake Center Lock Thru-axle 12x142 mm Rear Wheel - Shimano

The Zipp 404 Firecrest Disc Brake Center Lock 12x142 mm thru axle with 58 mm depth, the 404 Firecrest model for Tubeless is ideal for road racing, time trial and triathlon, big bottoms, and for riding on varied terrain. The inner width of the 23mm wheelset is perfect for running wider tubeless tyres at reduced air pressure.

It's a vital component of the Total Efficiency System, or TSE, an approach to speed in ever-changing road and driving conditions. Specifically, TSE focuses on overcoming specific barriers to speed: wind resistance, gravity, rolling resistance and vibration losses.

Zipp's ABLC Sawtooth technology uses an intricate dimple pattern to improve aerodynamic efficiency. The use of hookless (straight side) tires on the 404 Firecrest is an integral part of Making You Faster.

With the hookless system, the transition between the rim and tyre is smoother and more aerodynamic.
