Zipp 202 Firecrest Carbon Disc Front Wheel 2019

Zipp 202 Firecrest Carbon Disc Front Wheel. The delivery of speed, efficiency and responsiveness has always been the purpose of the Firecrest 202 wheel design. The 202 Firecrest Carbon takes road wheel performance to the next level. Equipped with the most advanced rim and hub technology that Zipp has created and is engineered to ensure the best disc brake stability. Additionally, the performance enhancing tubeless compatibility and World Tour level aerodynamics that Zipp have mastered, results in an exceptional road wheel that will help advance your race to the podium Aerodynamic Stability and Crosswind Control. It features the Firecrest rim profile, specially designed to provide air slicing aerodynamics and to be extremely stable in windy conditions. The rim design features the Zipp specific SawTooth dimple surface, which further reduces aerodynamic drag and helps to significantly increase control in strong crosswinds. It has been optimised to perform best with the modern wider tyre sizes up to 28mm 28c in width, the wider tyre width increases rolling speed and grip, while being more comfortable. When braking, the wider tyre profile provides a larger tyre contact patch with the road, ensuring greater stability and traction Fast, Responsive and Durable. The full carbon rim is amazingly flex free, which noticeably benefits power transfer from the rider to the road. It enhances the experience of confidence inspiring stability at all speeds, all weather conditions and across any terrain you are cycling on. To compliment this fantastic rim design is the Zipp 77D disc brake hub and top level Sapim CX Ray spokes. The addition of disc brake compatibility on the already high performance 202 Firecrest design creates a wheel that can satisfy every race day demand for performance and any season long requirement for durability and consistency Features Material Rim Carbon; Hub AlloyHub Model 77DHub Width 100mmRim Width Internal 21mm; External 28 9mmRim Type ClincherRim Depth 32mmSpoke Type Sapim CX RaySpoke Hole Count 24 HoleSpoke Pattern 2 CrossSpoke Length 284mmMax Tyre Pressure 125psi 8.62barsTrack Adaptable NoDimpled Rim Surface Yes11 Speed Compatible YesNipples Sapim Secure LockThru Axle Compatible YesWeight 705gFeatures Firecrest A unique to Zipp rim profile that provides more aerodynamic finesse than any other rim design. It also improves handling in crosswinds significantly and increases the ride quality enormously. 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 rims profile to further reduce high yaw drag and improve crosswind stability.
