Zipp 303 Carbon Tubular Rear Wheel 2018 Review

• Zipp 303 Carbon Tubular Rear WheelThe Zipp 303 Carbon Tubular Rear Wheel provides top-level, podium-proven performance and stability. Featuring an exceptionally stiff and light weight build while providing excellent power-transfer; it is perfect for long days climbing in the mountains, racing your way back down at full speed and touring across the roughest of cobbled streets. This full carbon construction features the unique Zipp ABLC dimpled rim surface, which is proven to significantly reduces air-drag and provides increased speed and stability throughout the duration of any riding session Enhanced Wind-Tunnel PerformanceThe 303 Firecrest wheel design has been fine-tuned and enhanced to the highest level of performance thanks to extensive wind-tunnel testing, which ensured that air drag would not affect stability or power-output when cycling. Every Zipp wheel is laced and constructed by hand, and tuned to the highest-levels of performance; many World Tour events have been won on Zipp wheels and customers receive the exact same quality as their Pro Race Teams Features: Hub Model: 177 Rim Outer Width: 26 5mm Rim: Carbon Tubular Rim Depth: 45mm Spokes: Sapim CX-Sprint Spoke Hole Count: 24 Hole Spoke Pattern: 2-cross Spoke Length Non-Drive: 272mm Spoke Length Drive: 270mm Max Tyre Pressure: 125 psi Track Adaptable: No SRAM XDR Compatible: Yes (supplied separately) Dimpled Surface: ABLC Sawtooth Nipples: Sapim, Secure-Lock Weight: 746gTechnologies: Visco-Elastic Constrained Layer Control (VCLC): Using a vibration absorbing material that is compressed between layers of solid carbon laminate on the rim surface. This technology means that when the rim received as impact from the road, a lot of the shock is absorbed by the VCLC system, resulting in a 10% reduction in road vibration. Carbon Bridge: Adding Kevlar, stitched into a 6 bundle co-axial thread and placing this at the rim edge allows Zipp to ‰Û÷capstone‰Ûª the top of each outside diameter bridge, providing an improved way to distribute impact forces. This gives from 28% to as much as 50% improvements in impact depending on the rim type and allows Zipp to increase the lateral stiffness with minimal weight penalty. 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‰Ûªs profile to further reduce high yaw drag and improve crosswind stability. 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 Buy Zipp Wheels & Tyres from Chain Reaction Cycles, the World’s Largest Online Bike Store.
