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 32mm 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: New Zipp graphics and cosmetic identity that scream speed Versatile endurance wheelset for the modern road bike with tubeless and hookless rim profile Lighter Weight than its predecessor, making it nimble and fast. Tubeless Made Easy, optimized tire bed sign allows for simple tool-free installation and removal with no need for an air compressor to seat the tire. Ultra-wide 25mm rim profile creates a better tire interface to be fast on or off the road New 40mm rim depth makes a light and aero wheel in every situation New ZR1 DB hub is engineered in Germany with better seal design for improved durability and quicker response with 66 points of engagement Ships with 12mm front and rear end caps Center locking rotor interface. Lockring is included with the wheels XDR™ or SRAM/Shimano driver bodies Campagnolo driver body sold separately
Zipp has equipped this model with tubeless tyre compatibility, so you can enjoy the benefits of superior stability and control as well as a lighter overall weight. Another highlight of this version is its disc brake compatibility, which means that you'll benefit from powerful and consistent braking performance during the most unpredictable of road conditions.

Zipp 303 Firecrest Carbon Tubeless Rear WheelZipp's 303 Firecrest Tubeless rim-brake rear wheel is an all-arounder for a new era of road riding. It's rich in heritage yet loaded with innovations. It's as adept in the mountains as it is on rolling hills, windswept farm lanes, or ferocious field sprints.Tubeless Ready Road Bike Rear WheelAt Zipp, they never rest on laurels. This rear wheel features a 19mm internal width and is tubeless ready. That means you can run lower tyre pressure for greater cornering grip and compliance with reduced rolling resistance without the risk of pinch flats.Lightweight Carbon with ABLC Sawtooth TechnologyWhen it comes to pure speed, the 303 Firecrest Tubeless packs a serious punch. It's lightweight with ABLC Sawtooth Technology, a complex dimpling pattern first developed for the brand's top-level NSW wheel lineup. This technology helps to achieve the optimization of low aerodynamic drag and crosswind stability, which they call AeroBalance.Rim Brake CompatibleZipp's ShowStoppertextured braking surface delivers unrivalled rim braking performance in wet or dry conditions.

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 optimising 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.Manufacturer's Part Number: ZPWH8532001 Black 700c SRAM XD SRAM XDR ZPWH8532000 Black 700c Shimano/SRAMBuy Zipp Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.
