404 Firestrike™ Carbon Clincher Limited
Firestrike™

From Zipp, the leading engineers of speed for more than a quarter century, a pioneering carbon clincher wheelset – the Zipp 404 Firestrike™ Carbon Clincher. Think limited availability, unlimited capabilities. 

The 404 Firestrike Carbon Clincher is designed for durability and impact resistance but, at 1,620 grams per wheelset, is also light weight. Simply put, Zipp set the industry standard for strength and durability in a carbon clincher.

With its versatile 58mm rim depth, the 404 Firestrike Carbon Clincher it stands as our pinnacle carbon clincher to overcome the resistive forces slowing you down – whether it’s aero drag, wind-induced steering torque, rain soaked roads, or tight corners. Each version of Firestrike has limited availability – we manufactured just four hundred and four (yes, 404) wheelsets each for the second edition of the 404 Firestrike Carbon Clincher and 404 Firestrike Tubular.

Additional innovations and features in the 404 Firestrike Carbon Clincher:

  • 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’s ImPress™ direct-print black razor graphic for improved aesthetics and weight savings over traditional decals.
  • Re-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.
  • Zipp Valve Extenders by Silca™ provides easy inflation with an external gasket for no annoying rattle at the valve hole.

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

  • Showstopper™ 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 the bearing pre-load. That means no bearing pre-load adjustment is ever required.

Each 404 Firestrike Clincher includes Zipp black titanium skewer, Zipp valve extender by Silca™, Zipp tube 700c x 23mm, Zipp rim tape 700c x 20mm, Zipp individual wheel bag and Zipp Platinum Pro Evo brake pads.

*188v10 hubset and associated hubset parts are not cross-compatible with the 188v9 hubset or hubset parts.

Peloton Features Firestrike  September 2014 [pdf]

In its Sept. 2014 issue, Peloton Magazine captures touts the exclusivity and innovations of Firestrike including greater stability, handing and stopping power in wet conditions.
Quote:
“Increasing confidence in crosswinds meant a new rim shape, yet one that would not lose any of its drag-reducing performance; to achieve this, the Firestrike is almost 2mm wider across the entire cross-section compared to Firecrest. New dimples in a wave pattern also help stability, and together result in a 34 percent reduction in side force. The wider rim increases handling confidence because, with internal width of 17.25mm, a tire’s volume increases and road feel improves.”

Firestrike™

The all-new Firestrike rim is the latest technology built on the same rim patent used in Firecrest. Using Firecrest as a building block, our engineers continued to develop around the principle technologies that made the rim shape great.

Carbon Clincher

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.
