DESCRIPTION

Zipp’s 303 Firecrest® Tubeless Disc-brake wheelset is designed for the real world… a world of imperfect conditions, road surfaces, and elements where the bottom line is simple. Efficiency = speed. It’s faster, lighter, and more capable over varied terrain—whether the surface is pavement in all its conditions or no pavement at all.

Deeply rooted in Zipp’s drive to conquer the Spring Classics, the new 303 Firecrest is remade with a purpose-made approach for the demands of modern road bikes. When it comes to going fast on a bicycle, efficiency means reduced: Wind resistance, rolling resistance, rider fatigue, weight. The 303 Firecrest Tubeless Disc-brake was designed using real-world direct measurements (vs. primarily wind tunnel or computer simulation). The results were huge. Its rim is slightly more bulbous in design than its predecessor, with a 30mm outside width, a 25mm internal width, and a 40mm rim depth. The profile provides low drag and an improved transition between rim and tire, boosting aero efficiency on the road. The wide rim stance also features less tire deflection for reduced rolling resistance. The combination of the wider tire, increased tire volume, and lower tire pressure helps to reduce rider fatigue by smoothing out the ride over imperfect pavement and road conditions—the tire and wheel system absorbs the shaking, not the rider.

At the center of the 303 Firecrest Tubeless Disc brake is a versatile and durable new hubset, the German-engineered ZR1 DB. This hubset features 66 points of engagement for quicker response. The 303 Firecrest Tubeless Disc-brake wheelset is for dedicated cyclists who aspire to the latest in technology. Its competitors… in races, against peers, or simply conquering personal limits. This is about becoming faster and matching your motivation to the most advanced technology.

 

FEATURES

TECHNOLOGY

 

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 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 innovations, our engineers have learned to look beyond just focusing on simply reducing aero drag while also minimizing the effects of crosswinds on dandling. This optimizing of aero efficiency and crosswind stability became known internally at Zipp as AeroBalance. The approach began with Firecreat technology and has been advanced with the introduction of the NSW lineup, especially with the Sawtooth technology found in the 454 and the 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 Firecrest's precise rim layup results in greater all-around efficiency for greater speed through reduced: Wind resistance, rolling resistace, gravity (weight + durability), vibrations losses.
