Zipp 202 NSW FCC Road Wheelset

. Zipp's 202 NSW Full CarbonClincher wheelset has been engineered to be the fastest accelerating andlightest set of wheels that the company has ever created; all achieved without sacrificing durability. Featuring industry leading aerodynamics and braking, the 202 NSW is a pinnacle achievement in road racing wheels on this rim depth This wheelset has been successfully recognised as possessing an exceptionally fast climbing rate while also being exceptionally strong and durable, making them fully suitable for every areaof cycling Instant Power Transfering Hubs. To push your performance to itshighest level, the featured 202 NSW rims are laced to Zipp's Cognition hubsets. The design of these hubs sit at the pinnacle of drivetrain engagement and provide an instant power transfer, making them a marvel in terms of rolling efficiency and durability Features MaterialRim Carbon; Hub Aluminium Hub ModelCognition Rim ModelZipp X32NSW Rim Depth32mm Rim Outer Width25 4mm Rim Inner Width16 25mm Rim TypeCarbon Tubular SpokesSapim CX Ray J Bend, 18H, Radial Spoke NipplesSapim Secure lock Max Tyre Pressure125psi Dimpled SurfaceABLC, SawTooth Weight615g front, 760g rearTechnologies CognitionThe ultimate in Zipp hub technology. Every time a conventional hubset starts to coast, friction within the freehub ratchet mechanism works like a drum brake to slow the rider down. The drag between the hub shell and driver body during coasting is considered an efficiency loss, especially for road wheels. High drag also can significantly contribute to chain dropping issues. The drag torque drives the cassette clockwise so the chain gets loose on the load side. The solution The rear Cognition hub with AxialClutch technology reduces drag by disengaging the ratchet mechanism when coasting. It then uses magnets to re engage once the rider starts pedalling. ShowstopperShowstopper 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. In order to improve this for the wettest of rides, Zipp have introduced a moulded in groove specifically tuned for the Zipp Tangente Platinum Pro EVO Brake Pad. The grooves have been optimized to interact with leading edge relative to the rotation of the wheel of the brake pad and the four cooling channels. The leading edge of the pad and first two channels efficiently wipe water and debris outward, cleaning and drying the braking surface, while the second two cooling channels have maximum interference with the grooves allowing greater braking force than a smooth rim. The cleaning effects of the groove and pad interaction improve brake feel and consistency even in dry conditions. ImPressZipps ImPress graphics technology prints graphics directly on the wheel, which allows the dimples to do what they were designed to achieve, to control vortex shedding and the rate at which air sheds off the wheel. Managing this is crucial to stability. ImPress graphics also give NSW a distinctive stealthy look. Hexfin Aerodynamic Boundary Layer Control ABLCThe 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 BuyZipp Wheels & Tyresfrom Chain Reaction Cycles, the Worlds Largest Online Bike Store.
