Zipp 808 Firecrest Carbon Tubeless Rear WheelZipp's 808 Firecrest Tubeless rim-brake rear wheel makes you faster with an 82mm rim depth that's fast, stable in crosswinds, and now tubeless-ready. That means you get all the aero benefits with having the ability to run lower tyre pressure for increased cornering grip and compliance and reduced rolling resistance, without the risk of pinch flats. This rear wheel is infused with technologies developed in Zipp's Indianapolis advanced development lab. Zipp's ABLC Sawtooth Technology uses a complex dimpling pattern to improve aero efficiency. Zipp's ShowStopper textured braking surface delivers unrivalled rim braking performance in wet or dry conditions. At the centre of the 808 Firecrest Tubeless rim-brake is a versatile and durable hub, the German-engineered ZR1. Zipp's wheel cosmetics make this rear wheel a perfect pairing of speed and style.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.ABLC SawtoothThe 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.AerobalanceZipp's sole mission is to help you go faster. That's why the brand's 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, its 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 Zipp's new HexFin ABLC dimples for improved airflow.Features: Rim Material: Carbon with UD Fibre finish and adhesive decals Use: Road Axle Type: QR 130mm (quick release) Internal Rim Width: 18mm Rim Depth: 82mm 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: 24 Spoke Pattern: 2 Cross Hub: ZR1 Rim Brake Axle Material: Aluminium Bearings: Cartridge - Stainless Steel Driver Mechanism: 6 Pawls Leaf Spring Driver Body Material: Aluminium Max Tyre Pressure: 125psi Max Recommended Rider Weight: 250lbs Single or Pair: Single rear wheel Weight: 1003g (approx)Technologies: New Zipp graphics and cosmetic identity that scream speed.
