Zipp 202 Firecrest Carbon Road Disc Rear. 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, makes the 202 Firecrest an exceptional road wheel that will help advance your race to the podium Compatible with Modern Wide Tyres. Featuring 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 Race Day Performance, Season Long Reliability. 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 177D 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. This wheel design ensures that you can brake later coming into corners, giving you the competitive edge and enables you to get the most out of every watt of effort, as you power your way to the front of the pack Features Material Rim Carbon; Hub Alloy Hub Model 177D Hub Width 135142mm Rim Width Internal 21mm; External 28 9mm Rim Type Clincher Rim Depth 32mm Spoke Type Sapim CX Ray Spoke Hole Count 24 Hole Spoke Pattern 2 Cross Spoke Length 284mm Max Tyre Pressure 125psi 8.62bars Track Adaptable No Dimpled Rim Surface Yes 11 Speed Compatible Yes Nipples Sapim Secure Lock Thru Axle Compatible Yes Weight 825gTechnologies 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 Buy Zipp Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.
