If you had to choose just one wheel, the 404 Firecrest Carbon Clincher is a savvy and speedy choice. With a depth and shape proven in all conditions, it’s the all-around performer and the standard by which all other wheels are measured. Its 58mm rim depth is a classic all-around performer that has carried athletes to victory in every kind of event and situation – every triathlon distance, breakaways, field sprints and hilly finishes. This latest iteration of the 404 Firecrest Carbon Clincher is infused with technologies developed in our Indianapolis advanced development lab. The results mean better performance out on the road: More speed, better control, and greater stopping power than its predecessor: More Speed: Revised rim profile for reduced aerodynamic drag developed by our advanced development team in Indianapolis, Indiana, USA. Greater AeroBalance™: ABLC™ Sawtooth™ Technology, a complex dimpling pattern first developed for our top-level NSW wheel lineup. This technology helps to achieve the optimization of low aerodynamic drag and crosswind stability, which we call AeroBalance. Better braking: Zipp’s ShowStopper™ textured braking surface delivers unrivalled rim braking performance in wet or dry conditions. Lighter Weight: The 404 Firecrest Carbon Clincher is 75 grams lighter than its previous iteration.

If you had to choose just one wheel for road riding and racing, the 404 Firecrest Tubeless is a savvy and speedy choice.ShowstopperZipp's 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. Showstopper is a complimenting pairing of a directional, moulded-in, texture with silicon carbide particles suspended in the surface resin. The current media blast process applied to all Zipp rims increases the surface roughness of the brake track providing the rider with consistent and responsive braking.AerobalanceZipp's sole mission is to help you go faster. That's why Zipp 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, Zipp's engineers have learned to look beyond just focusing on simply reducing aero drag. Instead, the goal now is to reduce aero drag while also minimising 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 works together with the brand's HexFin ABLC dimples for improved airflow.Hexfin Aerodynamic Boundary Layer Control (ABLC)The Sawtooth dimple design consists of 12 nodes that are specifically clocked to start aerodynamic shearing at a rate of 50hz at a rider speed of 20mph. Sawtooth accomplishes this by inducing small sheet vortices that shed at a low magnitude, but at a higher natural frequency, thus decreasing the laminar bubble effect on the aerodynamically shielded side of the rim's profile to further reduce high yaw drag and improve crosswind stability.Features: Rim Material: Carbon with UD Fibre finish and adhesive decals Use: Road Axle Type: QR 100 Caps (diameter 19mm) Internal Rim Width: 19mm Rim Depth: 58mm Rim Profile: Symmetrical Brake Compatibility: Rim Brake Size: 700c Tyre Compatibility: Clincher, Tubeless Ready Surface Texture: ABLC SawTooth Nipple Material: Aluminium Nipple Anti-rotation: Sapim Secure-loc Spoke Type: CX-Ray - Black Spoke Count: 18 Spoke Pattern: Radial Axle Material: Aluminium Bearings: Cartridge, Steel Max Tyre Pressure: 125psi Max Recommended Rider Weight: 250lbs Single or Pair: Single front wheelTechnologies: New Zipp graphics and cosmetic identity that scream speed.
