ZIPP Firecrest 404 Carbon Tubular Disc / DT Swiss 350 CL / Sapim CX-RAY 1540g wheelset

If you had to choose just one wheel, the 404 Firecrest should be your choice. With the depth and shape proven in all conditions, it’s the all-around performer and the standard by which all other wheels are measured. Its 58 mm rim depth is a classic all-around performer that has carried athletes to victory in every kind of event and situation – every triathlon distance, breakaways, field sprints and hilly finishes.

TECHNOLOGY:

Firecrest®
With the new proprietary Firecrest rim shape in Zipp‘s 202, 303, 404 and 808 Firecrest wheels, 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 and overall ride quality.

ABLC™
Advanced Boundary Layer Control (ABLC) refers to the patented and instantly recognizable dimpled pattern found on all of Zipp’s 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.

VCLC™
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 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.
