Roue à boyau Arrière Zipp 404 FirecrestLa roue à boyau 404 Firecrest est fabriquée avec la dernière génération de notre moyeu arrière 188, le V9, et le nouveau schéma de laçage de rayon pour la roue arrière, des perfectionnements améliorent la rigidité et la durabilité. Le nouveau moyeu a été développé en coopération avec le sprinteur Mark Cavendish de l'équipe cycliste Omega Pharma - Quick-Step est utilisé par d'autres des meilleurs cyclistes et triathlètes pro dont Pete Jacobs et Mirinda Carfrae.Cavendish a reçu les premiers prototypes de moyeu en janvier 2013 et il a parcouru 13 000 kilomètres en changeant continuellement les variantes, y compris lors de ses victoires d'étapes au Giro d'Italie et au Tour de France 2013. Ses commentaires ont permis d'optimiser la géométrie latérale du moyeu, sa rigidité et son poids.Le nouveau moyeu de 188/V9 dispose de plus gros roulements de précision en acier Suisse pour une durabilité accrue. Notre nouveau laçage « 3 croix virtuelle » des deux côtés de la roue arrière améliore la rigidité, apportant la rigidité 3 croix à un modèle 2 croix avec une nouvelle géométrie de rayon. Le 188/V9 a rigidité torsionnelle de 25 pour cent supérieure à un leader moyeu concurrent. Cette mesure de rigidité est essentielle pour le transfert direct de puissance à la roue arrière pour les sprints en danseuse et les montées. Le nouveau moyeu est aussi latéralement (côte-à-côte) plus rigide que sa rivale ou la précédente.Spécifications : Poids cycliste cycliste max recommandé : 113 kg Poids : <805g Moyeu utilisé : 188/V9 Profondeur de la jante : 58mm Largeur de la bande de freinage (Centre) : 25,34mm Largeur max : 26,53mm Largeur nominale de la jante du pneu : 18,00mm Nombre de rayons : 24 Largeur de rayon côté opposé à la transmission : 252mm Modèle de rayon côté opposé à la transmission : 2 Croix Modèle de rayon côté transmission : 2 Croix Longueur de rayon côté transmission: 250mm Moyeu 11 vitesses compatible : Oui Bande adaptable : Non Surface alvéolée : Oui Roulement en céramique : Pièces de rechange Têtes de rayons externes : OuiLe profil de jante de 58 mm de Zipp est un classiquede l'arsenal qui remonte au début des années 1990. Aujourd'hui, le 404 à boyau remporte encore des courses, de la Queen K à l'Alpe d'Huez. Désormais, avec la forme de jante aero Firecrest avancée, notre formidable exécutant représente une chance encore plus importante de gagner n'importe quelle course, quel que soit le terrain. Ce jeu de roue légendaire est disponible avec deux options d'écusson, le discret Beyond Black ou les autocollants plus distincts Classic White. Les deux options d'écusson disposent de moyeux anodisés noirs, de rayons noirs et de têtes de rayons noires.En contrôlant les flux d'air autour de l'arrière de la moitié de la roue, le 404 Firecrest est 9 secondes plus rapide que le modèle 404 précédant à plus de 40 km à un angle de vent modéré de 10 degrés. À des angles de vent plus élevées, les améliorations sont encore plus spectaculaires en termes de vitesse et de stabilité. Et parce que Firecrest déplace le centre de pression et le rapproche de l'axe de direction, les vent traversaux exercent moins de force latérale sur la roue. Il en résulte une conduite plus stable.Outre l'aérodynamisme et la stabilité, le profil plus large de la 404 Firecrest de 27,07 mm offre de nombreux autres avantages sur route. Grâce à sa rigidité latérale améliorée, la 404 Firecrest est encore plus sensible aux accélérations et plus précise dans les virages. Et sa structure composite est conçue pour amortir les chocs en fléchissant légèrement vers l'extérieur, ce qui vous donne un confort et une durabilité à long terme.Et même avec toutes les améliorations de la technologie Firecrest, la 404 à boyau Firecrest ne pèse que 1 445 grammes. Sur les montées, il jusqu'au bout des pieds avec des rivaux moins profonds et moins aero. Sur les plats, il rivalise avec des concurrents plus profonds et moins agiles. Si un jeu de roues peut le faire, c'est le 404 Firecrest.Acheter la roue à boyau Arrière Zipp 404 Firecrest sur Chain Reaction Cycles, le plus grand magasin de vélo en ligne du monde.

Zipp 303 Carbon Clincher QR Rear WheelPacked to the brim with Zipp's innovative technologies, the 303 is an all-carbon rear wheel clincher that's lightweight and responsive enough to suit riders of any skill level. A deep 45mm rim offers excellent aerodynamics while also being stiff enough to make for a smooth riding experience. Additionally, a wide rim of 26.4mm means better traction and power over rolling resistance, making this wheel more durable even on rough surfaces.Fully Optimised HubsetThis wheel comes with Zipp's 177 hubset, a favourite of professionals for its ability to pair to with Sapim CX Sprint spokes to offer remarkable torsional stiffness, making for a stable performance that maintains speed for longer.Easy to InstallThis rear wheel also features an ergonomic quick-release skewer, designed to fit neatly in the frame to aide with aerodynamics while also allowing for easy installation for your bike.Features: Hub Model: 177 Rim: Clincher Rim Width: 26.4mm Rim Depth: 45mm Brake Track Width: 26.4mm Spokes: Sapim CX-Sprint Spoke Hole Count: 24 Hole Spoke Pattern: Radial Max Tyre Pressure: 125psi / 8.62bars Dimpled Surface: ABLC SawTooth Nipples: Sapim Secure-Lock Weight: 835gFeatures: 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’s profile to further reduce high yaw drag and improve crosswind stability. 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 the 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. Visco-Elastic Constrained Layer Control (VCLC): Using a vibration absorbing material that is compressed between layers of solid carbon laminate on the rim surface. This technology means that when the rim receives an impact from the road, a lot of the shock is absorbed by the VCLC system, resulting in a 10% reduction in road vibration.Buy Zipp Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.

Zipp 202 Firecrest Carbon Disc Front WheelThe delivery of speed, efficiency and responsiveness has always been the purpose of the Firecrest 202 wheel design. The 202 Firecrest Carbon takes road wheel performance to the next level. Equipped with the most advanced rim and hub technology that Zipp has created and is engineered to ensure the best disc brake stability. Additionally, the performance-enhancing tubeless compatibility and World Tour level aerodynamics that Zipp have mastered, results in an exceptional road wheel that will help advance your race to the podium.Aerodynamic Stability and Crosswind ControlIt features the Firecrest rim profile, specially designed to provide air-slicing aerodynamics and to be extremely stable in windy conditions. The rim design features the Zipp specific SawTooth dimple surface, which further reduces aerodynamic drag and helps to significantly increase control in strong crosswinds. It has been optimised to perform best with the modern wider tyre sizes up to 28mm (28c) in width, the wider tyre width increases rolling speed and grip, while being more comfortable. When braking, the wider tyre profile provides a larger tyre contact patch with the road, ensuring greater stability and traction.Fast, Responsive and DurableThe full carbon rim is amazingly flex-free, which noticeably benefits power-transfer from the rider to the road. It enhances the experience of confidence-inspiring stability at all speeds, all weather conditions and across any terrain you are cycling on. To compliment this fantastic rim design is the Zipp 77D disc brake hub and top-level Sapim CX-Ray spokes. The addition of disc brake compatibility on the already high-performance 202 Firecrest design creates a wheel that can satisfy every race day demand for performance and any season-long requirement for durability and consistency.Features:Material: Rim: Carbon; Hub: AlloyHub Model: 77DHub Width: 100mmRim Width: Internal: 21mm; External: 28.9mmRim Type: ClincherRim Depth: 32mmSpoke Type: Sapim CX-RaySpoke Hole Count: 24 HoleSpoke Pattern: 2 CrossSpoke Length: 284mmMax Tyre Pressure: 125psi / 8.62barsTrack Adaptable: NoDimpled Rim Surface: Yes11-Speed Compatible: YesNipples: Sapim Secure LockThru Axle Compatible: YesWeight: 705gFeatures: Firecrest: A unique to Zipp rim profile that provides more aerodynamic finesse than any other rim design.

Zipp's 808 Firecrest balances both forces to give you an optimal wheel that gives back as much as you put in. A carbon fibre rim means aerodynamic performance without weighing down your bike and an 82mm deeper rim depth means better drag performance and increased stability. Plus, a wider rim means improved ride quality and greater rolling resistance management. All this results in a wheel that builds on Zipp's innovations with an eye to improving racer control.Excellent Cornering Road WheelWith the Cognition hubset, featuring Axial Clutch technology, you can maintain higher speeds even when approaching corners, thanks to an innovative ratchet mechanism that disengages as you coast. Combine this with a hubshell design that keeps bearings in place even under high radial spoke tension and you have a front wheel that saves you precious seconds and grants you the opportunity to edge ahead without risking damage to your bike.All-New Braking PowerZipp's ShowStopper technology brings new durability and function to the rim brake, taking advantage of suspended silicon carbide particles within the rim texture for increased braking power even in tougher conditions.Features:    Hub Model: Cognition    Rim: Clincher (Tubeless Ready)  Rim Width: 28mm  Rim Depth: 82mm   Brake Track Width: 26.4mm    Spokes: Sapim CX-Spring    Spoke Hole Count: 18 Hole    Spoke Pattern: Radial    Max Tyre Pressure: 125psi / 8.62bars    Dimpled Surface: ABLC SawTooth    Nipples: Sapim Secure-Lock    Weight: 857gTechnology:  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.  SawTooth: The name given to the Zipp NSW variable depth 53/58mm rim profile. This design is the result of rigorous wind tunnel and real-world testing. The rim shape takes natures elegant design solutions and combines their precise engineering finesse to deliver a wheel that performs like nothing else before.  ImPress: While some brands will sacrifice a little function for form, this technology from Zipp ensures you get a wheel that works as good as it looks. Graphics are printed directly onto the wheel, freeing the dimples to control vortex shredding and maintain your stability to the optimal level.Buy Zipp Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.

Zipp 202 NSW FCC Road WheelsetZipp's 202 NSW Full Carbon Clincher wheelset has been engineered to be the fastest accelerating and lightest 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 area of cycling.Instant Power Transfering HubsTo push your performance to its highest 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: Material: Rim: Carbon; Hub: Aluminium Hub Model: Cognition Rim Model: Zipp X32NSW Rim Depth: 32mm Rim Outer Width: 25.4mm Rim Inner Width: 16.25mm Rim Type: Carbon Tubular Spokes: Sapim CX-Ray J-Bend, 18H, Radial Spoke Nipples: Sapim Secure-lock Max Tyre Pressure: 125psi Dimpled Surface: ABLC, SawTooth Weight: 615g (front), 760g (rear)Technologies: Cognition: The 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. 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.
