Zipp 808 Firecrest Carbon Tubeless Rim Brake Wheel - REAR Only - Shimano HG11
Zipp’s 808 Firecrest® Tubeless rim-brake wheelset 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 tire pressure for increased cornering grip and compliance and reduced rolling resistance, without the risk of pinch flats. This wheelset is infused with technologies developed in our 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 unrivaled rim braking performance in wet or dry conditions. At the center of the 808 Firecrest Tubeless rim-brake is a versatile and durable new hubset, the German-engineered ZR1. Zipp’s new wheel cosmetics make this wheelset a perfect pairing of speed and style.
Our superior Carbon Clincher technology is the culmination of two years of intensive prototyping and testing. We worked with our composites supplier to develop an exclusive heat-resistant resin based on the materials used in motorsports brake systems. This proprietary technology improves heat management so substantially that all Zipp Carbon Clinchers pass stringent CEN safety standards.
With the industry-changing Firecrest rim shape, Zipp wheels fulfill our missing of making you faster at our most popular rim depths. Not only is Firecrest more aerodynamic than any other rim design, it improves handling in crosswinds and overall ride quality. Firecrest is the first aero profile that effectively controls airflow around the back half of the wheel. Its durability is durable enough for the Spring Classics as well as years of training and racing.
Our industry leading silicon carbide Showstopper brake track continues to evolve and improve, providing unmatched stopping power and modulation regardless of weather conditions or the length of the descent.
Zipp’s 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.
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 optimizing 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.
We want you to be beyond happy with your purchase from My Bike Shop! So most bikes, wheels and gear we sell are backed by our 30-Day Satisfaction Guarantee. We're able to offer this because every bike must meet our rigorous and meticulous 72-Point Inspection before being sold and shipped, and all wheels and gear must meet specific certification standards as well prior to shipping.
