Zipp 303 Firecrest Carbon 碟刹 后轮 Tubular Shimano/SRAM-自由轮 标准 graphic

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. Zipp`s 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.

ABLC®
Revised ABLC® (Aerodynamic Boundary Layer Control) smooths airflow off the rim surface increasing the frequency of the vortex shedding, which creates smaller vortices, providing unmatched stability and control on even the windiest days.

Firecrest
Zipp`s proprietary Firecrest® rim rewrote the fundamentals of wheel making, resulting in improved aerodynamics, ride quality, wheel strength and stability in even the strongest of crosswinds. As a result, the entire Firecrest family of wheels - from the 202 to 808 Firecrest - makes a bigger difference in more ways than ever including being laced into the new 77/177 hubset.

Firecrest technology, with rims that maintain a near-constant width almost all the way to the spoke bed, is the first aero profile that effectively controls airflow around the back half of the wheel. By moving the center of pressure - the focal point of side forces on the rim - to its optimal location near the steering axis, Firecrest offers stable, predictable handling at every wind angle. As they discovered when developing the Zipp 303 to thrive under unforgiving conditions at the Spring Classics, a wider rim such as used in Firecrest wheels increases lateral stiffness for sprinting and cornering, yet offers greater vertical compliance for more control, comfort, and durability on rough surfaces.
