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.

Campagnolo Centaur 11sp Rear DerailleurThe Campagnolo Centaur 11 Speed Rear Mech is highly versatile and offers fast and reliable shifting, thanks to Campagnolo's redesigned trajectory angle and their Ultra-Shift geometry. This design ensures precise operation with reduced friction and maximum shifting rigidity. Also, the Centaur is only made in one cage size and compatible with cassettes with up to a 32 tooth sprocket, so there's no need to swap the mech when you want to run a different cassette range. The Centaur rear mech features trickle-down technology from Campagnolo's top-end models, making it a race ready component, but at a more wallet friendly price!Features: Material: Aluminium Version: 2x11-Speed Cage Length: Medium Largest Sprocket: 32t Smallest Sprocket: 11t Weight: Approx. 230gBuy Campagnolo Components from Chain Reaction Cycles, the World's Largest Online Bike Store.

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.
