Zipp® is proud to unveil its most technically advanced tubular wheel ever, the 404 Firestrikeâ„¢ Tubular, while also updating its groundbreaking 404 Firestrike Carbon Clincher. Our introduction of the 404 Firestrike Carbon Clincher a year ago began a new era of technical innovation for Zipp.

Think limited availability, unlimited capabilities. The Firestrike platform quickly emerged as Zipp’s launching pad for the best of the best Speed Weaponry. As new designs, technologies and manufacturing techniques are proven, they are rolled into new versions of the 404 Firestrike. With its versatile 58mm rim depth, the Firestrike lineup stands as our pinnacle offering for aerodynamic efficiency, crosswind stability, durability, and braking performance. Each version of Firestrike has limited availability – we’re manufacturing just four hundred and four (404) wheelsets each for the new Firestrike Tubular and Carbon Clincher.

Introducing Carbon Shieldâ„¢

A key development within the 404 Firestrike Tubular is Carbon Shieldâ„¢, a new ply sequence of unidirectional carbon as well as a new mold-tool design and mold process to achieve optimal laminate properties for a strong and light weight tubular rim. This new process was verified and refined during in 2013 during test-riding sessions with top riders from one of Zipp’s UCI ProTeams. These sprinters and strongmen hammered away on prototype wheels built with a variant of Carbon Shieldâ„¢ on le Carrefour de l’Arbre, one of Paris-Roubaix’ punishing five-star cobblestone sectors. The pros took repeated test runs on the cobbles at race speed, including with lower than normal air pressure, yet the rims remained undamaged. That innovation was rolled into the 404 Firestrike Tubular. This season, 404 Firestrike Tubular wheels already are is in use by the Axel Merckx-led Axeon Cycling Team.

New features in the 404 Firestrike Tubular and Carbon Clincher:

– Zipp’s ImPressâ„¢ direct-print black razor graphic for improved aesthetics and weight savings over traditional decals.
– Newly designed titanium quick-release skewers have a wider more ergonomic handle to provide more leverage for opening and closing. When closed, the lever contours neatly with the frame.
– CeramicSpeed® bearings are the lowest resistance hybrid ceramic (ceramic balls and steel races). Smooth rolling bearings put every last watt into moving you toward your goal.
– Zipp Valve Extenders by Silcaâ„¢ provides easy inflation and feature an external gasket for no annoying rattle at the valve hole.

Zipp’s Firestrike design, which draws on the same rim patent used in Zipp’s Firecrest® wheel lineup, also includes premium performance advancements:

– Showstopperâ„¢ brake track technology applies a molded in brake track pattern and introduces a Silicon Carbide (SiC) surface for wet weather braking. Showstopper technology delivers greater stopping power in wet conditions than any carbon wheel ever produced, offering braking on par with aluminum braking surfaces.
– CFD (computational fluid dynamics) designed Firestrike rim shape provides a 34% reduction in side force while maintaining the aero performance of our Firecrest rims, for the ultimate in aero balance.
– Revised ABLC® (Aerodynamic Boundary Layer Control) smooths airflow through more frequent and smaller vortices, providing unmatched stability and control on even the windiest days.
– The Zipp 88/188v10 hubset adds torsional stiffness gained through the use of a 2-cross lacing pattern utilizing Sapim® CX-Ray® spokes and precision-set bearing pre-load. That means no bearing pre-load adjustment is ever required.
