Zipp 454 NSW Carbon Clincher Rear Wheel 2019 Review

• Zipp 454 NSW Carbon Clincher Rear Wheel. The Zipp 454 NSW Carbon Clincher is an evolution in the world of ¬†competitive road wheels. Zipp took inspiration from creatures in nature who ¬†have evolved to the highest levels of speed, control and efficiency. The humpback ¬†whales fast and graceful movement through the water thanks to the edges of its ¬†pectoral fins, combined with the unique texture of shark‚Äôs skin to help it ¬†glide through the water were design features that attributed Zipp’s creation of ¬†the 454 NSW wheel standard Optimised Aerodynamic Drag Reduction. Featuring a wind-tunnel proven, performance enhancing biometric 53/58mm ¬†Sawtooth rim profile, the 454 NSW design provides aerodynamic drag and side ¬†force reduction to levels that other wheels cannot achieve. The AeroBalance and ¬†Hyperfoil fins help slice through the air for optimised efficiency and the ¬†inner diameter of the rim features HexFin ABLC dimples to keep stability and ¬†airflow at its maximum. These technologies work together seamlessly thanks to ¬†their ability to shed air away from the rim surface; it is so successful that ¬†these technologies will feature on all future Zipp wheels Aerodynamic Finesse, Efficiency and Stability. All this added aerodynamic finesse and drag reduction leads to exceptional rider stability and more efficient power transfer to the road. The unique rim profile combats the air vortex, which slows other riders down; the Zipp NSW design saves energy, provides confidence inspiring stability in gusty, strong crosswinds and transfers more power output from the rider to the road than any other wheel on the market Exceptional Ratchet Efficiency. At the heart of this 454 NSW wheel is the Zipp Cognition hub, which is ¬†the ultimate in hub technology. A conventional hub effectively functions like a ¬†drum brake once the rider stops pedalling and begins to coast, the drag caused ¬†by the freehub ratchet and the hub shell is a considerable efficiency loss. The ¬†Cognition hub engages as normal when you‚Äôre putting the power down. However, ¬†when you stop pedalling the ratchets are pulled away from the driver via powerful ¬†internal magnets; it effectively it puts the bike in neutral gear. The moment ¬†you rotate the pedals forward, the ratchet will engage once-more and apply the ¬†power instantly Features: ¬†Material: Rim: Carbon; Hub: Alloy ¬†Rim Model: X454NSW ¬†Rim Depth: 53/58mm ¬†Rim Inner Width: 17mm ¬†Rim External Width: 26 4mm ¬†Rim Surface: ABLC HexFin Technology ¬†Spokes: Sapim CX-Ray ¬†Spoke Count: 24 ¬†Spoke Lacing: 2-cross ¬†Max Tyre Pressure: 125 psi ¬†Hub: Cognition ¬†Speed: 11-Speed ¬†Weight: 835gTechnologies: Cognition: The ultimate in Zipp hub technology. Every time a conventional hub set starts to coast, friction within the freehub ratchet mechanism works like a drum brake to slow the rider down. The drag between hub shell and driver body during coasting is considered as 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 Showstopper: Showstopper 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 ImPress: Zipp‚Äôs 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 (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‚Äôs profile to further reduce high yaw drag and improve crosswind stability Buy Zipp Wheels & Tyres from Chain Reaction Cycles, the World‚Äôs Largest Online Bike Store.
