Zipp 303 Firecrest Tubular Disc 700c Rear Wheel

Zipp’s 303 Firecrest Tubular Disc-brake wheelset offers game-changing innovations for performance-minded cyclists.
This wheelset was developed to meet the needs of our sponsored professional racers – road and cyclocross – as well as
any cyclist who prefer the time-proven ride qualities of riding tubulars. The 303 Firecrest Tubular Disc-brake
features key technologies first developed for Zipp’s halo-level NSW wheelsets. Our ABLC™ Sawtooth™ dimple design that
extends all the way to the edge of the rim. The rim features construction upgrades that deliver improved impact
resistance. These innovations enhance a wheelset that’s excelled in two of pro cycling’s harshest proving grounds, the
Spring Classics and the Cyclocross World Cup. At the center of the 303 Firecrest Tubular is a versatile and durable
new hubset, the German-engineered ZR1 DB.

Technologies

ABLC SawTooth

ABLC Sawtooth dimple design helps manage air flow around the rim, and contributes to create a faster, more stable
wheel.

AeroBalance

Zipp’s sole mission is to help you go faster. That’s why their wheels are race-ready before they’re camera-ready. For
years, Zipp has used a combination of testing methods – wind tunnel, CFD computer simulations, pro athlete
evaluations, on-road testing, and the RollingRoad ride simulator – to refine aero performance to new levels of
excellence. Over the decades of innovation, Zipp’s engineers have learned to look beyond just focusing on simply
reducing
aero drag. Instead, the goal now is to reduce aero drag while also minimizing the effects of crosswinds on handling.
This optimizing of aero efficiency and crosswind stability became known internally at Zipp as AeroBalance. The
approach began with Firecrest technology and has been advanced with the introduction of the NSW lineup, especially
with the Sawtooth technology found in the 454 and 858 NSW. Sawtooth accomplishes this with a series of patented
fin-shaped Hyperfoil nodes along the inner diameter of the rim that work together with their new HexFin ABLC dimples
for improved airflow.
