A NEW CHAPTER IN SPEED.
Naturally, Zipp chose to launch their groundbreaking Firecrest® and Carbon
Clincher designs with their most versatile wheels, the Zipp Z404 Firecrest
Carbon Clincher Bicycle Wheel. Its 58 mm rim depth is a classic all-around
performer that has carried athletes to victory in every kind of event –
triathlons, criteriums, breakaways, field sprints and even Grand Tour mountain
In fact, Zipp’s first full-carbon clincher wheelset, the 404 Firecrest Carbon
Clincher Front Bicycle Wheel, has been described as the most heavily anticipated
wheelset of all time. And following two years of development for its
revolutionary rim shape and carbon technology, Zipp’s confident that the 404
Firecrest Carbon Clincher lives up to the hype.
The 404 Firecrest Rear Bicycle Wheel features the 188 hubset, with a 7.5mm-wider
bearing stance in the rear hub, and a driveside hub canted by 2 degrees for
improved stiffness and reliability. For 2013, the this 404 Firecrest Rear
Bicycle Wheel comes in stealthy Beyond Black decals and features black anodized
hubs, black spokes and black nipples.
Its Firecrest aero profile is the first deep-profile carbon clincher design to
offer the superior aerodynamics, ride quality, strength and handling of a wider
rim body. Yet the 404 Firecrest Carbon Clincher weighs just 1,525 g/wheelset,
putting it among the lightest deep-profile carbon clinchers available.
Designed specifically to account for the differences in airflow patterns between
clincher tires and tubulars, the 404 Firecrest Carbon Clincher far exceeds the
aero performance of any other clincher wheelset in its class. As Zipp proved
with the Paris-Roubaix-winning 303 Tubular, a wider rim offers greater vertical
compliance for control and comfort on rough surfaces while increasing lateral
stiffness for sprinting and cornering. The same holds true for Firecrest rims
with clincher tires. And because the hook beads are farther apart, the tire
itself takes on a more stable shape without adding rolling resistance.
Heavy continuous braking on carbon surfaces can cause spikes in rim temperature
and tire pressure that impact performance and handling – especially with
clincher tires. To solve this challenge, Zipp’s U.S.-based composites supplier
created a new heat-resistant resin exclusively for Zipp. This technology
improves heat dissipation so substantially that ours are the only carbon
clinchers to pass stringent European safety testing without limitations on rider
weight or brake pad options.
Recommended and approved
These brake pads have been tested and approved by Zipp for use with their
tubular and all carbon clinchers. Failure to comply with these recommendations
could negate your warranty.

With the new Firecrest rim shape in Zipp’s 404 and 808 Tubulars and Carbon
Clinchers, 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, wheel strength, and overall ride quality.
Boundary Layer Control) - Advanced Boundary Layer Control (ABLC) refers to
the patented and instantly recognizable dimpled pattern found on most Zipp rims.
ABLC smoothes airflow across the rim's surface and is tailored to every model
from the 202 to the Sub9 disc. 2009 sees the third-generation of ABLC, with up
to 4 times more dimples than before.
Constrained Layer Control) - Visco-Elastic Constrained Layer Control (VCLC)
uses a vibration-absorbing material sandwiched between layers of rigid carbon
laminate in the rim. When the wheel receives an impact from the road, much of
the shock is absorbed by the VCLC system, delivering a 10% reduction in
88/188 Hub Technology -
Every aspect of Zipp’s 88 and 188 hubs sets a new benchmark. The standard steel
bearings are the roundest in the industry. The 17mm axle is the stiffest of any
road hub they've tested. The wire EDM-cut hub internals are the most precise.
The SHIFT spoke hole technology is the most durable. When it comes to precision
and performance, there's really no comparison.
