ABLC Sawtooth: ABLC Sawtooth dimple design helps manage air flow around the rim, and contributes to create a faster, more stable wheel. AeroBalance: Zipp's sole mission is to help you go faster. That's why our wheels are race-ready before they're camera-ready. For years, Zipp has used a combination of testing methods - wind tunnel, CFD computer simulations, pro athlete evaluations, on-road testing, and the RollingRoad ride simulator - to refine aero performance to new levels of excellence. Over the decades of innovation, our engineers have learned to look beyond just focusing on simply reducing aero drag. Instead, the goal now is to reduce aero drag while also minimizing the effects of crosswinds on handling. This optimising of aero efficiency and crosswind stability became known internally at Zipp as AeroBalance. The approach began with Firecrest technology and has been advanced with the introduction of the NSW lineup, especially with the Sawtooth technology found in the 454 and 858 NSW. Sawtooth accomplishes this with a series of patented fin-shaped Hyperfoil nodes along the inner diameter of the rim that work together with our new HexFin ABLC dimples for improved airflow.Manufacturer's Part Number: ZPWH8532001 Black 700c SRAM XD SRAM XDR ZPWH8532000 Black 700c Shimano/SRAMBuy Zipp Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.
Zipp 858 NSW Carbon Tubeless Rear WheelZipp's ultimate aero weapon is now tubeless ready. That means you get the many aero advantages of the 858 NSW Tubeless rim-brake rear wheel with the added benefit of increased cornering grip and compliance with reduced rolling resistance. The rear wheels' 19mm internal width is optimised for running wider tyres at reduced air pressure. The 858 NSW's undulating 77/82mm-deep rim shape, the brand's proprietary Sawtooth profile, takes design cues from nature for Zipp's highest performing wheel when it comes to aero efficiency and crosswind stability. These structures inspired Zipp advanced development engineers to, for the first time, systematically apply biomimicry to solve the complex challenge of designing a wheel, with the undulating Hyperfoil nodes, that reduce both aerodynamic drag and side force. Simply put, the 858 NSW Tubeless is ideal for those focused on triathlon, time trials, or aggressive road riding.SawtoothSawTooth is the name given to Zipp NSW's patented variable depth 53/58mm rims. Developed utilising the principles of the emerging science of biomimicry, Zipp engineers began the rigorous aero development process of SawTooth utilising the wind tunnel, CFD, and real-world testing. The result is a rim shape that takes nature's most elegant design solutions and combines engineering precision to deliver a wheel that performs unlike any made before. This patented new rim shape achieves something conventional aero wheels cannot; it simultaneously reduces both aerodynamic drag and side force for the ultimate in AeroBalance. Sawtooth accomplishes this with a series of patented fin-shaped Hyperfoil nodes along the inner diameter of the rim that works together with Zipp's new HexFin ABLC dimples for improved airflow. The result is Zipp's highest performing rear wheel ever realized with both aero-drag reduction and reduced side force at all wind yaw angles. This is important because higher wind yaw angles are where bike handling is most affected by the wind.ShowstopperZipp's industry-leading Showstopper brake track continues to evolve and improve, providing unmatched stopping power and modulation regardless of weather conditions or the length of the descent. 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.Axial ClutchWith Cognition's Axial Clutch technology, Zipp has reduced drag by disengaging the ratchet mechanism when coasting. With less internal hub drag a rider can pedal less when drafting in a headwind, achieve higher speeds when coasting in an aero tuck, or opt to stop pedalling a moment sooner before entering a corner and bank that wattage for use exiting the corner. Axial Clutch technology also allows riders to maintain speed through corners that don't require braking input, thereby increasing corner exit speeds. Inside the Axial Clutch mechanism, Zipp uses magnets, rather than steel springs, to move and engage Zipp's lightweight Metal Injection Moulded (MIM) ratchet rings for unmatched reliability and consistent operation. With 36 points of engagement that all interlock simultaneously, there isn't a more secure freehub mechanism on the market.ImpressThis rear-wheel employs Zipp's ImPress graphics technology, which prints graphics directly on the wheel, to help allow the dimples to do what they were designed to do - help control vortex shedding, the rate at which air sheds off the wheel. Managing this is crucial to stability.Features: Rim Material: Carbon with UD Fibre finish with Impress technology Use: Road Axle Type: QR 135mm (quick release) Internal Rim Width: 18mm Rim Depth: 82mm Rim Profile: Symmetrical Brake Compatibility: Rim Brake Size: 700c Tyre Compatibility: Clincher, Tubeless Ready Surface Texture: ABLC HexFin Nipple Material: Aluminium Nipple Anti-rotation: Sapim Secure-loc Spoke Type: CX-Ray - Black Spoke Count: 24 Spoke Pattern: 2 Cross Hub: Cognition Axle Material: Aluminium Bearings: Cartridge - Stainless Steel Driver Mechanism: Axial Clutch Driver Body Material: Aluminium Max Tyre Pressure: 125psi Max Recommended Rider Weight: 250lbs Single or Pair: Single rear wheelTechnologies: New Zipp graphics and cosmetic identity that screams speed, applied using Zipp's ImPress direct-print technology. 19mm internal width and tubeless compatibility for optimisation of wider tyres with lower tyre pressure.

So you can approach corners at higher speeds, and ultimately, save time. A star-flanged straight-pull hubshell design on the rear hub distributes the load placed on the hub flange away from the bearings. Zipp also developed a unique scalloped edge hubshell design for the front hub (front wheel available separately). This scalloped design maintains the bearing bore diameter when high radial spoke tension is applied. That means you get bearings that quietly stay in place, roll faster, last longer, and provide a laterally stiffer hub. Impress: Zipp has employed ImPress graphics technology on this model, which prints graphics directly on the wheel, to help allow the dimples to do what they were design to do - help control vortex shedding, the rate at which air sheds off the wheel. Managing this is crucial to stability. Sawtooth: SawTooth is the name given to Zipp NSW's patented variable depth 53/58mm rims.

As with the mechanical parts, the rear derailleur represents the pride and joy of the EPS project and encompasses a series of technologies and innovations that allow shifting speed to be optimised and guarantee unprecedented precision, even in the case of multiple shifting with 11 sprockets at a timeThe EPS rear derailleur is comprised mainly of a mechanical structure, derived from the mechanical gear and composed of a derailleur rod/parallelogram/derailleur cage, of a worm screw enabled by an electronic actuator. As with the derailleur, the electronic rear derailleur actuator is composed of a gear motor and a sensor, the built-in resolver, that reads its movementsThe geometry of the parallelogram has been made more rigid and optimised to promote interaction with the electronic partsThe lower and upper bodies, the parallelogram and the carbon derailleur cage are moved by a screw system and lead worm screw (not a spring screw) which, in turn, is enabled by the electronic actuator that communicates with the DTI. The built-in resolver inside the actuator is capable of reading the movements of the rear derailleur at any time and optimising its position by communicating with the DTI (Digital Tech Intelligence)The rear derailleur is also equipped with a play recovery system using a helicoidal spring that optimises stability and precision and keeps operation and performance constant over time, even after many kms have been coveredAs with the mechanical rear derailleur, it is possible to optimise its position with respect to the frame and chain by acting on two adjusting screws: the screw that adjusts the mechanical end stop and the screw that adjusts the distance between the upper pulley and sprockets. By using these screws it is possible to optimise the installation of the rear derailleur and increase the precision of its operationDTI: Digital Tech Intelligence is housed inside the Power Unit and it continuously monitors the signals that arrive from all the EPS components, thus managing their operationMULTI-SHIFTING: There are no longer any limits to Multi-shifting and the choice is at the fingertips of the cyclistRIDE BACK HOME: The uncoupling mechanism of the rear derailleur is useful if the battery runs out on the road, allowing you to manually uncouple the rear derailleur to position it on which ever sprocket you requireWATER PROOF: In order to achieve the IP67 classification, all the electronic components of the EPS system underwent a series of tests, which proved their ability to function perfectly under one meter of water for at least 30 minutes
