58 mm rim profile is a classic in Zipp®’s arsenal that dates back to the early
1990s. These days, the Zipp 404 Tubular is still winning races from the Queen K
to L’Alpe d’Huez. Now, with the advanced Firecrest® aero-rim shape, Zipp’s
leading all-around performer is an even greater threat to win any race on any
terrain. For 2012, the Zipp 404 Firecrest Tubular Front Bicycle Wheel is
available in Zipp’s all-new Beyond Black with black-anodized hubs, spokes, and
reflective black logos.
controlling airflow around the back half of the wheel, 404 Firecrest is 9
seconds faster than its predecessor 404 model over 40 km at a moderate 10-degree
wind angle. At higher wind angles, the improvements are even more dramatic in
terms of speed and stability. That’s because Firecrest moves the center of
pressure closer to the steering axis so crosswinds exert less side force on the
wheel. The result is a more stable ride.
Beyond aerodynamics and stability, the 404 Firecrest’s wider 27.5 mm-wide
profile offers a slew of other benefits on the road. The upgraded lateral
stiffness makes the 404 Firecrest even more responsive to accelerations and more
precise when cornering. And its composite structure is designed to absorb
impacts by flexing slightly outward – which gives you a comfortable ride and
Even with all the improvements from Firecrest technology the 404 Firecrest
Tubular’s weight is a light 1,282 grams a wheelset. On the climbs, it goes
toe-to-toe with shallower, less aero rivals. On the flats, it hangs with deeper,
less nimble competitors. If anyone wheel can do it all, it’s the 404 Firecrest.
new for 2012, the 404 Firecrest is getting the brand new 88/188 hubset, with a
7.5mm-wider bearing stance in the rear hub.

With the new Firecrest rim shape, 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
Advanced Boundary Layer Control (ABLC) refers to the patented and instantly
recognizable dimpled pattern found on most of Zipp’s 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
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 vibration.
Carbon Bridge™ -
Carbon Bridge uses a Kevlar® thread in a co-axial helix stitch to bind sheets of
carbon to each other in Zipp’s tubular rims. Because Kevlar is 350% more impact
resistant than carbon, it can disperse shock more evenly throughout the carbon
laminate, making for a rim that is practically bulletproof. In particular,
Carbon Bridge reduces the vulnerability of the rim's tire bed, the area most
susceptible to damage from impact.
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 Zipp has 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.
