ZIPP wheelset 28" 404 Firecrest Carbon Clincher | Tubeless | Center Lock 12x100 mm | 12x142 mm thru axle | Shimano Road freehub body
With a profile height of 58 millimeters, the Zipp 404 wheels have been the right choice for road races, time trials or fast tours in varied terrain for decades. Equipped with the latest technologies, the current generation is ready for use on modern road bikes and seamlessly continues this legacy. At 23 millimetres, the inner rim width has increased significantly compared to its predecessors. As a result, the rims not only offer wider tires optimum support at low air pressures, they also integrate the tires into the rim profile in an extremely aerodynamically efficient manner. In addition, the hookless design creates an almost seamless transition between the tire and rim flanks. The elimination of the hooks also makes the rim flanges more robust in the event of punctures and contributes to the significant weight saving compared to the previous versions. In combination with further optimizations in the structure of the carbon layers, the weight of the wheelset has been reduced to 1559 grams (including rim tape and tubeless valves). An optimized rim bed ensures easier tire mounting.
Total System Efficiency (TSE)
The 404 wheels were developed using the TSE approach. The development goal was to find the best possible wheel design to overcome the speed barriers that exist under realistic riding conditions. These include wind resistance, gravity and rolling resistance as well as vibration losses in poor road conditions.
ABLC Dimples
The ABLC dimples (dimples on the outside of the rim) help to reduce air resistance and ensure very high crosswind stability, especially at larger angles of attack.
Zipp ZR1 hubs
The Zipp ZR1 hubs were developed in two years of development work in Germany. Their outstanding feature is the extremely fine-toothed freehub body design of the rear hub with 66 engagement points per wheel revolution, which allows the ZR1 to respond to acceleration without delay. The fine toothing is realized via a system of 6 pawls, 3 of which engage in an offset manner. The design of the seals is based on the high-end Cognition hubs and provides more protection and durability with a larger dust cap behind the freehub body and better seals.
NOTE: Due to the hookless profile, the Zipp 404 wheels are only suitable for use with ETRTO-compliant tubeless tires. However, the corresponding tubeless tires can be ridden on the wheels with a tube without any problems. You can find an overview of all compatible tires for your Zipp hookless wheel here.
