Mix and match.
The 404 Firecrest Carbon Disc Brake Road Clincher Wheel is Zipp's answer to keeping this versatile and aerodynamic rim profile current with the shifting trends toward disc brakes for nearly all cycling disciplines. Whether you're looking to run even rim depth front to rear on your new disc-equipped steed or aiming to mix the dish, this wheel delivers confident speed and predictable handling no matter the conditions.
The 404 is an ambitious rim profile designed to bring near-tubular feel to the clincher world, featuring an aerodynamic 58mm rim depth and a 16.25mm internal rim width that gives the tire a solid platform to reduce instability caused by the side bulge effect found in tires mounted to narrower rims. It's not as wide as some of the exaggerated rim widths we're seeing more of every year, but it does sit in the sweet spot of ISO and ETRTO recommendations for 25mm tires.
Zipp testing shows that the rim design creates a more stable overall structure while providing greater radial compliance for a comfortably controlled ride over rough road surfaces. The design also increases stiffness under load from hammering and cornering, making for snappy jumps and sharp lines through corners.
Aerodynamics are a key element of the 404 Firecrest's versatility. It features an updated version of Zipp's signature Aerodynamic Boundary Layer Control (ABLC) dimpling, which uses strategically placed and sized dimples across the rim's surface to smooth airflow and reduce drag. ABLC boasts aerodynamic advantages at real-world yaw angles of 10 to 20 degrees. This compares favorably to wheels that hit low drag numbers at yaw angles of five to 10 degrees, conditions that rarely occur outside of a wind tunnel. In non-techy talk, that means these wheels are faster the competition in the windy conditions you'll actually encounter on the road.
Zipp uses its 77 disc hub in the front and its 177 disc hub in the rear. Featuring a new platform and graphics for 2016, these hubs boast increased bearing protection over their predecessors and are ready to roll without any pre-load adjustment. The rear hub is compatible with a separately sold XD driver body, allowing options for a wider cassette range of up to a 10-42t if needed. As an added bonus, driver bodies can be swapped out without having to re--dish the wheel to get back up and running. Each wheel includes an updated quick-release skewer with a widened handle that provides better leverage for setting the wheel and sits closer to the frame when closed.
Each Zipp 404 Firecrest Carbon Disc Brake Road Clincher Wheel comes with 12 x 100mm and 15 x 100mm end caps for the front wheel and 12 x 135mm and 12 x 142mm end caps for the rear wheel. Each wheel also includes a Zipp Tangente quick-release skewer, rim tape, and a core valve extension.
