First launched in 2011, Zipp’s 404 Firecrest wheelsets are not only firmly established as one of the fastest wheels on the market, but also they have arguably helped shape the entire category of modern aerodynamic wheels. This iteration, to use the company’s term, is no less than a ‘Speed Weapon’; a ‘weapon’ that boasts a 58mm-deep rim and weighs less than ever at 1470g. It is now cheaper than before, making this a product that’s virtually a no brainer. Whether you’re looking for a wheelset fit for a Spring Classic, time trial, triathlon, or simply to compete against your mates on the weekend club run, this is an option which is hard to look past. Single Purpose: Speed Whereas the 303 Firecrest is Zipp’s premium all-rounder, which’ll happily serve its rider on or off road, the 404 is all about going fast. Somewhat unusually, the company aren’t claiming to have made a more aerodynamic rim, quite the opposite. As the rim is wider, the shape is actually less aerodynamic than the previous version. However, a multitude of other enhancements — what has been termed Total System Efficiency (TSE) — has enabled the developers to produce a faster-overall wheelset. In addition to examining how wind resistance affects the wheels, the effect of gravity, rolling resistance, and vibration losses have also been tested. Notably, the internal width of the rim is now wider at 23mm, and has been optimised for a tyre of 25–28mm — depending on rider size. This allows the tyre to be ran at a lower pressure and in turn means it can roll more smoothly over imperfect road surfaces, increasing efficiency and making for a faster wheel overall. The weight of the wheelset has also been reduced, increasing its speed and lessening the impact of gravity when going up-hill. All this adds up to a wheel that is faster on varied terrain and ever-changing riding conditions. Going Hookless Hookless rims are slowly becoming the de-facto choice for wheel makers, at least in the high-end wheel space. What this means is, instead of the traditional ‘hook’ on the inside of the rim, the wall is straight. This comes with a number of manufacturer-claimed benefits. For one, with a hookless rim, the transition between the tyre and rim is less abrupt, which helps to cut a cleaner shape through the air. As well as the performance benefits, hookless rims are also cheaper, easier, and more environmentally friendly to produce, all of which amounts to cost savings for the buyer. The Hub Spinning the wheelset is an all-new, German-engineered, versatile and durable hubset. Using a six-pawl freehub, with 66-point engagement, the hub has a pick-up angle of 5.45 degrees so that when you put the power down, it’s translated to forward motion almost instantly. Overall, if you are looking for just one wheelset for road riding, be that for racing or simply for fun, then the 404 Firecrest is a difficult option to look past.

Zipp 404 NSW Carbon Tubeless Rear WheelThe 404 NSW is the ultimate all-rounder and provides fantastic climbing efficiency and comfort while being more than capable of maintaining speed on the flat and stability during high-speed descents. Its stiffness and strength have been proven on the Spring Classic race events across cobbled streets and rough, uneven terrain but are still light enough to inspire rider confidence when sprinting out of corners.CognitionThe 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 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.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.

Zipp 454 NSW Carbon TL Rear Road Disc WheelDelivering fantastic speed, comfort and durability on every mile, this road bike rear wheel is equipped with a high-quality carbon rim construction and some of Zipp's finest technologies. Featuring a Sawtooth rim with Hyperfoil nodes and HexFin ABLC dimple pattern, this model is engineered for top aero and crosswind-stability performance with an undulating 53/58mm rim depth. Wind tunnel, CFD and real-world tested, its patented shape achieves something conventional aero wheels cannot by simultaneously reducing both aerodynamic drag and side force for the ultimate in AeroBalance.Tubeless Ready Carbon Road Bike Rear WheelZipp's ultimate all-around speed weapon is now tubeless ready. This means you get all of the aero advantages of the 454 NSW Tubeless Disc-brake wheel with the added benefit of increased cornering grip and compliance with reduced rolling resistance. Its 19mm internal width is also optimised for running wider tubeless tyres at reduced air pressure for improved stability, greater comfort and fewer chances of flats or punctures.Centre Lock Disc Brake CompatibilityReady for wherever your next ride takes you, this rear wheel is kitted out with Centre Lock disc brake compatibility for powerful and consistent braking operation. Keeping you in full control of the ride, the Zipp 454 NSW Carbon TL Disc Brake CLock Rear 2021 is a perfect upgrade for riders who want to enjoy greater speed, aerodynamics and an overall lighter weight on their road bike.Features: Rim Material: Carbon Rim Finish: Unidirectional (UD) Fibre Rim Graphics: Impress Technology Axle Size: 12x142mm Use: Road Rim Type: Clincher Rim Profile: Symmetrical with Hooks Inner Rim Width: 19mm Hub: Cognition DB with scalloped edge hubshell design Freehub: Multiple options available to select Drive Side Spoke Length: 248mm, 254mm Non Drive Side Spoke Length: 252mm, 254mm Tyre Compatibility: Tube-type or tubeless tyres Tubeless Ready: Yes Size: 700c Brake Compatibility: Centre Lock disc brake Single or Pair: Single Weight: 955gTechnologies: Cognition Hub: With the Cognition hub's Axial Clutch technology, Zipp reduced drag by disengaging the ratchet mechanism when coasting. 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. 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 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 work together with HexFin ABLC dimples for improved airflow. The result is Zipp's highest performing wheel ever released 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. Axial Clutch: With Cognition's Axial Clutch technology, Zipp 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 use magnets, rather than steel springs, to move and engage the lightweight Metal Injection Molded (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. XDR Freehub Option: The XDR driver body option is available to select separately. It is a universal mounting system for cassettes that incorporate cogs with fewer than 11 teeth. It allows for lighter and more versatile drivetrains without requiring new rear axle standards, cassette tools or hub redesigns. The XDR interface is 1.85mm longer than XD and is designed for road hub applications. XDR driver bodies are compatible with all XD cassettes when the cassette is installed with a 1.85mm spacer.Manufacturer's Part Numbers: Shimano/SRAM 10/11 speed: ZPWH8617000 SRAM XD XDR 10/11/12 speed: ZPWH8617001Buy Zipp Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.
