The essence of Zipp

ALTERNATE VIEWS
404 Tubular

A 58mm rim profile has been in Zipp’s product line ever since we designed the first deep-section carbon rims back in the early ‘90s. Today, the 404 continues to rack up varied results like stage wins from sprinter Thor Hushovd and rouleur Nicki Sørensen at the 2009 Tour de France, and Craig Alexander’s 2008 victory in Kona. From your local criterium to l’Alpe d’Huez, the 404 is a threat to win any race on any terrain.

The current version of the 404 is faster than ever with the third generation of our patented ABLC dimpling pattern and a fully toroidal rim shape derived from over 100 hours of wind tunnel testing. The toroidal profile also offers the benefits of added stiffness, due to a slight widening of the rim, and better braking with an angled brake track.

Like all our tubular rims, the 404 is built with our Carbon Bridge technology that dramatically increases impact resistance with a Kevlar thread running perpendicular to the carbon laminate. Between those layers of carbon lies our VCLC system, which uses a shock-absorbing material to reduce vibration by 10% and keep your wheels glued to the pavement under all conditions.

ABLC™  (Aerodynamic Boundary Layer Control)

Advanced Boundary Layer Control (ABLC) refers to the patented and instantly recognizable dimpled pattern found on most of our 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.

VCLC™  (Visco-Elastic 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 vibration. Read More

Carbon Bridge™

Carbon Bridge uses a Kevlar® thread in a co-axial helix stitch to bind sheets of carbon to each other in our 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. Read More

88/188 Hub Technology

Every aspect of our 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 we've tested. The wire EDM-cut hub internals are the most precise. The SHIFT spoke hole technolgoy is the most durable. When it comes to precision and performance, there's really no comparison. Read More
