CeramicSpeed OSPW System Shimano 9100 + 8000 CoatedThis CeramicSpeed OSPW System - Shimano 9100 - Coated features the same construction as the standard model, but it has been developed to take performance optimisation even further and the watt savings start at 2.4 watts. The ceramic bearings in this model have been coated with a special treatment to further reduce friction and increase protection from wear and tear. A thin coating is also applied to the bearing races, to increase corrosion resistance.Shimano Specific Pulley WheelsBecause of the design of the 9100 series derailleurs, the R&D team at CeramicSpeed tested and concluded that the best performing combination of oversized pulleys for the Shimano 9100 series is a 13-tooth upper and 19-tooth lower pulley. The design of this Shimano-specific OSPW System is very strong and stiff to ensure a high durability factor. In-house tests show that the higher the tooth count, the longer pulley wheel lasts.Optimum PerformanceThis revolutionary OSPW System is developed, produced and assembled by hand in Denmark. Designed to be a plug-and-play fit, it's the result of an in-depth development process and has been finely tuned to provide optimal performance. Created to answer the need for less friction (as much as 60%), increased speed and a more efficient drivetrain, the OSPW System gives back what other drivetrains take: watts.Features:Material: Cage: Carbon, Polyamide; Bearing: Polyamide, Steel, Ceramic; Castors: AluminiumBearings: Ceramic type 607Pulley Teeth: top 13T, bottom 19TSpeed: 11-SpeedCapacity: 32TSpecifically designed for Shimano Dura-ace 9100/9150Use: Road, Triathlon, RanndoneurWeight: 57gMaintenanceIt’s important that you properly lubricate your bearings in order to ensure optimal performance and maximum longevity. Add oil to the outside of the bearing seal, so that oil can penetrate the bearing. Do this when you lubricate your chain, or if you have washed your bike or have been riding in wet or muddy conditions.Buy CeramicSpeed Components from Chain Reaction Cycles, the World's Largest Online Bike Store.

Dérailleur arrière SRAM GX Eagle (12 vitesses)Le dérailleur arrière GX Eagle à 12 vitesses de SRAM bénéficie de la technologie Roller Bearing Clutch de type 3 de SRAM. Procurant un changement de vitesse fluide, il affiche des performances de transmission précises, régulières et silencieuses grâce à la technologie dont il est doté et qui est issue des modèles de transmission Eagle de gamme supérieure. Les technologies X-Actuation et H-Horizon garantissent que les changements de vitesse involontaires et les sauts aléatoires entre les pignons de la cassette appartiennent désormais au passé.Caractéristiques :Matériau : aluminium (chape), acier (ressort, galet), acier inoxydable (visserie)Dents maximums : 50Compatibilité : toutes les transmissions EaglePoids : 290 gTechnologies :Technologie Cage Lock : incluse dans le dérailleur arrière, cette technologie permet l'installation et le retrait de la roue, ainsi que l'installation de la chaîne en toute facilité et de manière très rapide. Il vous suffit de pousser la chape vers l'avant pour créer un relâchement et l'enclencher.Technologie Roller Bearing Clutch : elle offre une stabilité maximale de la transmission, même sur les terrains les plus rigoureux. Avec la technologie Roller Bearing Clutch (RBC), le dérailleur rebondit et les sauts de chaîne sont éliminés sans perdre en précision.Technologie X-Actuation : conçue spécifiquement pour les transmissions SRAM 1X, cette technologie assure des passages de vitesse pointus et consistants sur toute la cassetteX-Horizon : la conception de parallélogramme droit X-Horizon limite tous les mouvements de l'axe horizontal, rendant impossibles les changements de vitesse involontaires tout en réduisant également la force nécessaire aux changements. Pour un changement de vitesse plus rapide et précis, la conception unique du grand galet supérieur maintient un intervalle de chaîne constant pour toutes les vitesses.Technologie X-Sync : les bords des dents carrées et hautes des galets et plateaux X-Sync s'engagent plus tôt dans la chaîne que les dents traditionnelles en forme de triangle. Pour vous offrir les meilleures performances possibles lors de conditions boueuses, les galets de dérailleur X-Sync ont été conçus avec des renfoncements dégageant la boue des roulements et maillons internes. Ces galets font partie intégrante des transmissions SRAM 1X à l'efficacité et aux performances exceptionnelles.Achetez des composants SRAM sur Chain Reaction Cycles, le plus grand magasin de vélo en ligne au monde.

SRAM Force 1 11sp Rear DerailleurThe SRAM Force 1 Rear Mech implements all of the shifting accuracy and durability from the SRAM mountain bike derailleur design to provide exceptional off-road performance for cyclocross use.Quiet and Smooth Shifting PerformanceThe internal clutch design eliminates chain slack, making it almost impossible for the chain to fall of the chainring whilst cycling; a real benefit when riding on rough terrain. It also creates a noticeably smoother, quieter and higher performing drivetrain configuration for your bike.Features: Cage Material: Aluminium Pulley Bearings: Steel sealed cartridge bearings Pulley Wheel Size: 12T Speed: 11-Speed Cable Pull Ratio: Exact Actuation Maximum Sprocket Size: Short Cage: 26T; Medium Cage: 36T; Long Cage: 42T Weight: Short Cage: 430g; Medium Cage: 434g; Long Cage: 439gTechnologies: Cage Lock: Wheel removal and installation, as well as chain installation, becomes faster and simpler. Just push the cage forward to create slack and lock it into place. X-Sync: The X-Sync pulley features a 12-tooth design that helps control the chain’s lateral movement Roller Bearing Clutch:  Maximum drivetrain stability even through the most punishing terrain. With Roller Bearing Clutch technology, derailleur bounce and chain slap are eliminated without sacrificing precision. Exact Actuation: Simplified and stabilised shifting over tight cog spacing found on modern cassettes. By using exact cable tension, the end result is the easiest index shifting system to set up and it stays that way. X-Horizon: The ‘straight parallelogram’ design limits all movement to the horizontal axis, which makes ghost shifting impossible while also reducing shift force. For quicker, more exact shifting, the large upper pulley offset design maintains a constant chain gap across all gears.Buy SRAM Components from Chain Reaction Cycles, the World's Largest Online Bike Store.

Dérailleur arrière Campagnolo Potenza HO (11 vitesses)Le dérailleur arrière Potenza HO à 11 vitesses de Campagnolo adopte les mêmes technologies et le même design que le modèle haut de gamme Super Record, mais avec légèrement plus de poids du fait de l'omission de sections en fibre de carbone. La technologie Embrace dont est doté ce dérailleur est l'une des caractéristiques majeures : elle assure une interface ultra-efficace de la chaîne et de la cassette, une adhérence sûre à la chaîne, plus de résistance à l'usure et un excellent transfert de la puissance.Spécifique aux cadres équipés de freins à disqueCette version HO (hydraulique optimisée) a été spécialement conçue pour être utilisée sur des cadres équipés de freins à disque et d'un espacement de patte arrière plus important de 12 x 142 mm. Elle comprend un maillon de fixation adapté pour un retrait plus facile de l'axe transversal et des dents plus larges sur le galet supérieur pour des changements de vitesse précis sur les lignes de chaîne les plus extrêmes.Caractéristiques : Corps supérieur en polymère technique ultraléger renforcé en fibre de verre Technologie de changement de vitesse multiple permettant 3 changements de vitesse à la fois Technologie Embrace pour une meilleure efficacité de la transmissionCapacité maximale de la cassette : 11-29 dents (chape courte), 11-32 dents (chape moyenne) Poids : 200 g Technologies :Ultra-Shift : ce système de contrôle développé par Campagnolo est considéré par tous comme le plus rapide et le plus précis qui existe. Grâce à lui, vous pouvez déplacer la chaîne simultanément de trois pignons vers le haut et de cinq vers le bas. De plus, le design du levier permet des changements de vitesse encore plus légers, tout en conservant le « clic » trouvé sur les toutes les commandes Campagnolo.Technologie Embrace : cette technologie augmente le nombre de dents de pignon enveloppées par la chaîne pour des changements de vitesse fluides, rapides et précis. Il a été démontré qu'elle optimise les fonctions du dérailleur arrière, même quand vous utilisez des cassettes extrêmes, telles que celles à 11-32 dents.Achetez des composants Campagnolo sur Chain Reaction Cycles, le plus grand magasin de vélo en ligne au monde.
