  • 303 Firecrest Carbon Tubular Disc-brake

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

    AeroBalance
    Zipp’s sole mission is to help you go faster. That's why our 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, our 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 our new HexFin ABLC dimples for improved airflow.

    TSE Technology
    Zipp’s TSE Technology (Total System Efficiency) was developed by our engineers in the Nest Advanced Development Lab in Indy. This approach to carbon-wheel manufacturing means the 303 Firecrest’s precise rim layup results in greater all-around efficiency for greater speed through reduced: Wind resistance, rolling resistance, gravity (weight + durability), vibration losses.
