Big Advantage For Smaller Riders
Zipp’s 404 650c Firecrest Carbon Clincher wheelset offers smaller athletes superior aerodynamics, stability, durability… and proper fit. It’s a simple premise, really. But for smaller athletes it has been a challenge to find the most advanced, highest performance wheelsets. With limited options in the 650c size, many of these cyclists ride standard 700c wheels and lose out on the increased efficiencies of a correct fitting wheel.
Smaller athletes never have to make this sacrifice again. The 404 650c Firecrest Carbon Clincher allows smaller bikes to fit smaller athletes. After all, road bikes were made in two wheel sizes – 700c and 650c – to keep handling and positioning proportional.
The 404 650c Firecrest Carbon Clincher stands at the forefront of the fit revolution while also building on the Zipp 404’s already legendary status. Its 58mm rim depth is a classic all-around performer that has carried athletes to scores of victories in triathlons, time trials, criteriums and road races. It also features two of Zipp’s most significant innovations – our proprietary Firecrest® rim shape and Carbon Clincher technology.
At the center of the 404 650c Firecrest is Zipp’s 77/177 hubset with best-in-class durability and improved bearing protection with no pre-load adjustment needed. The result is improved stiffness, durability, simplicity and versatility.
Precision-engineered hubs along with Firecrest technology create something special. Firecrest rims have a near-constant width from brake track to spoke bed. That shape more effectively controls airflow and the wheel’s center of pressure to result in greater aerodynamics, improved handing in crosswinds and overall ride quality. Our Carbon Clincher technology uses an exclusive resin, based on materials used in motorsports braking systems, that effectively tolerates the incredible spikes in heat caused by braking. When used with Zipp’s Tangente Platinum Pro Evo brake pads, the 404 650c Firecrest Carbon Clincher provides reliable modulation and stopping power. And for all those times you’re not on the brakes, you get the low rolling resistance and ease of use of a clincher.
Available in two decal options, the stealthy Matte Black or the distinctive Matte White decals. Each 404 650c Firecrest Carbon Clincher wheel comes with Tangente Platinum Pro Evo brake pads, Zipp Integrated Valve Extender with valve-core wrench, rim tape and quick release.
This wheelset is not tubeless compatible.

With the new proprietary Firecrest rim shape in our 202, 303, 404 and 808 Firecrest wheels, Zipp wheels make a bigger difference in more ways than ever. Not only is Firecrest more aerodynamic than any other rim design, it improves handling in crosswinds and overall ride quality.
Our superior Carbon Clincher technology is the culmination of two years of intensive prototyping and testing. We worked with our composites supplier to develop an exclusive heat-resistant resin based on the materials used in motorsports brake systems. This proprietary technology improves heat management so substantially that all Zipp Carbon Clinchers pass stringent CEN safety standards.
ABLC™ (Aerodynamic Boundary Layer Control)
Advanced Boundary Layer Control (ABLC) refers to the patented and instantly recognizable dimpled pattern found on all of our carbon rims. ABLC smoothes airflow across the rim's surface and is tailored to every model from the 202 to the Super-9 Disc. The third-generation of ABLC has up to four times more dimples than before.
Electron Discharge Machining allows us to cut the materials for our rear hub drive internals after they’ve been hardened through heat treating, negating the warping and imprecision caused by the heat-treating process.
Zipp is the only company specifying Swiss made highly specialized ball bearing cartridges. Working with a family owned Swiss bearing manufacturer, Zipp is able to attain a superior level of bearing smoothness and long life. Zipp ball bearings are specified to 10 millionths of an inch tolerance, guaranteeing that they are at least 2.5 times rounder and better matched than most company’s “high precision” balls, and more than five times tighter than most “precision” balls.
