Zipp’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 Wheel At 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 Technology When 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 Compatible Zipp’s ShowStoppertextured braking surface delivers unrivalled rim braking performance in wet or dry conditions. At the center of the 303 Firecrest Tubeless rim brake is a new versatile and durable hub, the German-engineered ZR1. Item Top Features Continued: - Zipp graphics and cosmetic identity that scream speed - New ZR1 hub is engineered in Germany with better seal design for improved durability and quicker response with 66 points of engagement - Built with Sapim CX Sprint J-bend spokes - Tubeless ensuring secure performance even when ridden at lower tire pressures - Versatile 45mm rim profile that’s fast, stable and versatile - ABLC Sawtooth dimple design helps manage air flow around the rim, and contributes to create a faster, more stable wheel - Showstopper textured brake track delivers superior modulation and shortest stopping distances in wet and dry conditions - XDR or SRAM/Shimano driver bodies available to select - Ships with QR end caps, quick-release skewers - Campagnolo driver body sold separately Technologies: Showstopper: Our industry-leading Showstopper brake track continues to evolve and improve, providing unmatched stopping power and modulation regardless of weather conditions or the length of the descent. 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 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.

Reflective artwork Wheel Size: 700c Tubeless Ready: Yes ASTM Category: 2 Single or Pair: Pair Weight Limit: 109kg (cyclist) Weight: 1590gTechnologies: 2-Way Fit: 2-Way Fit profile for tubeless and clincher. Fulcrum have developed 2-Way Fit technology to ensure the perfect compatibility of our tubeless rims with normal clincher types and tubes. 2-Way Fit road bike wheels are perfectly multipurpose for tackling every situation. Thanks to a special impression in the valve area, the tubes are fitted with maximum precision while keeping the tube perfectly stable inside the tyre. Housing the valve for tubeless tyres is also risk-free, with the unquestionable advantage that there are never any air infiltrations caused by non-ideal positioning when fitting. Rim Dynamic Balance (RDB: The concept is simple and elegant: balance the weight of the gasket, with an item of similar weight placed on the exact opposite side. Ceramic Ultra Smooth Bearings (USB): Fulcrum has a long-standing reputation for the extremely high performance of its hubs in terms of smoothness and reliability. The hubs with USB ceramic bearings (Ultra Smooth Bearings) further enhance the triathlon and road bike wheels' smoothness and reduce weight and the need for maintenance. Comparative tests have shown that USB bearings are 50% smoother than standard bearings. Now improving your performance during the race or simply going for a ride with your friends will be easier. AFS Axle System: The Axial Fixing System is the solution developed by Fulcrum to fix the disc brake to the hub. The constraint granted by the butt area of the release mechanism, greater than in familiar standard ones, makes it possible to obtain greater structural rigidity and therefore more precise and powerful braking. 2:1 Two-to-One Spoke Rato - Disc Brake: The advantages are truly striking. By pressing the brake, the front wheel maintains the right trajectory and does not deviate, while the rear wheel, precisely due to this spoking system, reaches a high level of torsional stiffness that enables the optimal transfer of power to the wheel. The 2:1 Two-to-One system also allows to reduce the unit load sustained by each spoke, and then to minimise the mechanical stress which will give a long life to the wheel. High Strength Aluminium: Special aluminium - the best aluminium wheels require carefully chosen materials. For "High strength Aluminum", Fulcrum R&D uses only the best aluminium alloy 6082, with artificial ageing T6 temper that stabilises the alloy and gives it maximum life and reliability. Aluminium 6082 has the highest strength of the 6000 series and has replaced 6061 in many applications. It is generally used for high-stress applications.Manufacturer's Part Number: FULC0146626 Black 700c Shimano FULC0146627 Black 700c SRAM XD SRAM XDRBuy Fulcrum Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.
