Zipp 808 Firecrest Carbon Tubeless Rear WheelZipp's 808 Firecrest Tubeless rim-brake rear wheel makes you faster with an 82mm rim depth that's fast, stable in crosswinds, and now tubeless-ready. That means you get all the aero benefits with having the ability to run lower tyre pressure for increased cornering grip and compliance and reduced rolling resistance, without the risk of pinch flats. This rear wheel is infused with technologies developed in Zipp's Indianapolis advanced development lab. Zipp's ABLC Sawtooth Technology uses a complex dimpling pattern to improve aero efficiency. Zipp's ShowStopper textured braking surface delivers unrivalled rim braking performance in wet or dry conditions. At the centre of the 808 Firecrest Tubeless rim-brake is a versatile and durable hub, the German-engineered ZR1. Zipp's wheel cosmetics make this rear wheel a perfect pairing of speed and style.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.ABLC SawtoothThe 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's profile to further reduce high yaw drag and improve crosswind stability.AerobalanceZipp's sole mission is to help you go faster. That's why the brand's 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, its engineers have learned to look beyond just focusing on simply reducing aero drag. Instead, the goal now is to reduce aero drag while also minimising 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 works together with Zipp's new HexFin ABLC dimples for improved airflow.Features: Rim Material: Carbon with UD Fibre finish and adhesive decals Use: Road Axle Type: QR 130mm (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 SawTooth Nipple Material: Aluminium Nipple Anti-rotation: Sapim Secure-loc Spoke Type: CX-Ray - Black Spoke Count: 24 Spoke Pattern: 2 Cross Hub: ZR1 Rim Brake Axle Material: Aluminium Bearings: Cartridge - Stainless Steel Driver Mechanism: 6 Pawls Leaf Spring Driver Body Material: Aluminium Max Tyre Pressure: 125psi Max Recommended Rider Weight: 250lbs Single or Pair: Single rear wheel Weight: 1003g (approx)Technologies: New Zipp graphics and cosmetic identity that scream speed.

Zipp’s 808 Firecrest® Carbon Clincher is pure engineering science. It has to be. To achieve speed with an 82mm rim depth is one thing, but to be fast but also high crosswind stability, well, that requires serious attention to detail. Yet that’s just what the 808 Firecrest Carbon Clincher accomplishes – speed with stability, what we call AeroBalance™ – which has made it a longtime favorite of triathletes, time trial specialists, as well as any cyclist in search of free speed. At Zipp, that search for aero efficiency is unrelenting. To that end, the latest iteration of the 808 Firecrest Carbon Clincher provides more speed, better control, and greater stopping power than its predecessor: More Speed: Revised rim profile for reduced aerodynamic drag developed by our advanced development team in Indianapolis, Indiana, USA. Greater AeroBalance™: ABLC™ Sawtooth™ Technology, a complex dimpling pattern first developed for our top-level NSW wheel lineup. This technology helps reduce high yaw drag while improving crosswind stability. This helps to achieve the optimization of low aerodynamic drag and crosswind stability, which we call AeroBalance. Better braking: Zipp’s ShowStopper™ textured braking surface delivers unrivalled rim braking performance in wet or dry conditions. Lighter Weight: The 808 Firecrest Carbon Clincher is 55 grams lighter than its previous iteration.

Zipp 808 NSW Carbon Tubeless Rear WheelZipp's 808 NSW Tubeless rim-brake rear wheel features a rim shape that aerodynamically integrates wider tubeless tyres for a new era of high-performance road cycling at the brand's deepest rim depth, 82mm. The 808 NSW Tubeless allows you to run tubeless or traditional clinchers. The benefits of tubeless include superior flat protection, the ability to run lower pressures, and a smoother ride with a high cornering grip and low rolling resistance. The 808 NSW Tubeless' 19mm internal rim width and corresponding outer rim shape are optimised for aerodynamic optimisation with 25mm tyres. Zipp's wheel cosmetics gives this rear wheel a perfect pairing of speed and style.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.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.

Zipp 858 NSW Carbon Tubeless Rear Wheel - Black - Shimano/SRAM}, Black
  • £899.99

  • Saving you £58

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.

Zipp Zipp 303 S Carbon Disc Rear Road Wheel - Black - Shimano/SRAM}, Black
  • £519.99

Zipp 303 S Carbon Disc Rear Road WheelTaking its design from the higher-spec Firecrest 303 model, this rear wheel is ideal for modern "go anywhere" road bikes. Zipp has also updated this model with a wider rim to improve rider comfort, handling and aerodynamics. Expanding greatly on its heritage of conquering the Spring Classics, this 303 wheel maintains its ideal-for-every-terrain 45mm rim depth. However, this model adds a significantly wider internal width to provide greater performance and ride quality in almost every measurable way. Road bikes are more versatile than ever no matter the road surface, but just as fast as before. The 303 S offers an entirely new rim profile and design to optimise rider performance on this new breed of bike. This wheelset is tubeless compatible and designed for disc-brake bikes, allowing the ability to run wide tires at lower pressures for race-ready speed on or off the tarmac.45mm Deep Rear WheelThe 303 S is among Zipp's lightest wheels, optimised for top aero performance with a 28mm tyre but capable of handling gravel tyres up to 50mm wide. The key innovation is in the 303 S's rim design. Its 45mm rim depth is the same as its predecessor, the 302 Disc brake. But its external rim width is 2mm wider, at 27mm, and its tyre bed is a full 7mm wider, at 23mm internal width. That rim platform is designed to be the fastest with a 28mm tyre. The wide rim optimises tyre profile to allow lower tyre pressure. That helps to reduce rolling resistance and provides a more compliant ride. The result of all this is a 10 watt savings vs. a top peer wheel in total power required to ride 40kph on a flat road with a 28mm tyre, according to internal Zipp testing.This ground-breaking wheel also features all-new cosmetics, setting the rider apart from the pack, and comes at a very attractive price.Please Note: Shimano/SRAM freehub option is for 11 speed Shimano/SRAM XD cassettes.
