Description
Optimized For All Out Speed
The Zipp 404 Firecrest wheelset has been an icon of cycling speed for the last three decades, and now, it's updated with the latest developments in aerodynamics and tubeless technology.
The 404's heritage as Zipp's icon of speed extends back decades, and its future is even brighter. At 58mm deep, the 404 Firecrest Tubeless is ideal for road races, time trials and triathlon, and gran fondos.
The wheelset's 23mm internal width is perfect for running wider tubeless tires at reduced air pressure. That is a vital component of Total System Efficiency, or TSE, an approach to speed on ever-changing roads and riding 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 dimpling pattern to improve aero efficiency.
Zipp's use of hookless (straight side) rims in the 404 Firecrest is integral to Making You Faster. With hookless, the transition between the tire and the rim is more seamless and aero. Zipp's hookless rims have more efficient resin distribution, which means lighter, stronger wheels.
Outdoor testing commissioned by Zipp revealed the real-world gains of Zipp TSE. A bike-and-rider system weighing 85kg (187lbs) on the new 404 Firecrest with 25mm tires required 286 watts to maintain a speed of 40kph. That's a 4-watt saving compared with the previous model 404 Firecrest.
At the center of the 404 Firecrest Tubeless Disc-brake is a versatile and durable hubset, the German-engineered ZR1 DB. If you had to choose just one wheel for road riding and racing, the 404 Firecrest Tubeless Disc brake is a savvy and speedy choice.

Reviews
I got these for a steal through BTD. I was debating building a set of wheels with a new set of DT180 hubs... Then I started pricing things out. A new set of hoops alone ended up being the same price as these fully built on sale.
I live in Chicago, and these perform incredibly well anywhere here as expected. They are solid, and very stable overall. Crosswinds can catch you from time to time, but still nothing to really worry about. Engagement is solid and clean. Hub sound is that of a thousand angry bees. Look great, feel great, smell great. Paired with Pirelli Race TLR, these things are smooth as butter, and will get you there in a Zipp�
Love this wheelset! These aero wheels are fast, lightweight and the hub is solid and engages quickly. I had a set of Enve 45 Foundation which I liked, but these are roughly the same weight (maybe even a bit lighter) with a bigger aero benefit. I didn't feel the crosswinds any more with these than I did with the Enves. I personally love the look of them as well. They are hookless so there's a bit of tire compatibility issue but other than that I can't find any fault.
BTD have been great, prompt shipping and I was even able to get these on sale.
I've only had one ride on these so far but love them. They definitely ride smooth accelerate quick and maintain speed. The one difference is they can only be pumped to 72.5psi. So, if you are remotely heavy, as in over 180 pounds the smallest tie you can run is 28mm.
