RECORD REAR DERAILLEUR
New mechanical rear derailleur Record 12 Speed: Precision, lightness and flexibility. The aim in developing the new Record 12 Speed mechanical rear derailleur was to improve all the performance and functional parameters. This is reflected in the new shape, which, thanks to 3D embrace technology, better embraces the sprockets and has a double action: The chain traction is always perfect, which benefits speed, power and shifting precision and ensures an optimum distance between the rear derailleur and sprockets at all times. In addition, the swivel bracket is designed for a connection with sprockets from 11 to 32 teeth, which is why a single model can be used for all sprocket packages in the range. The upper part of the Record 12 Speed mechanical rear derailleur housing is made of technopolymer and reinforced with carbon fibre in order to increase or decrease its resistance and weight, while the rear stops on the rear derailleur are equipped with adjusting screws to facilitate adjustment.
TOTALLY RENEWED DESIGN
The new shape of the external components allows the rear derailleur to move at a different angle. The new interior design keeps the chain closer to the sprocket package, ensuring better power transmission, stronger and safer traction, better chain/sprocket connection and better durability of components subject to wear.
The special gear inside the rear derailleur body (which acts on a spring with a rectangular cross section) allows the component to move along a path that follows the curve of the sprockets exactly, on cassette 11-23 as on the new 11-29.
ALUMINIUM SHAFT FASTENING SCREW
New 2-part system with 53% weight reduction compared to steel and 22% weight reduction compared to titanium for the same strength and stiffness - Longer component life.
CARBONFIBRE PARALLOGRAM PLATE
Extreme stiffness and reduced weight. For higher shifting precision and longer component life.
PARALLELOGRAMM WITH ULTRA-SHIFT GEOMETRY
Maximum rigidity of the rear derailleur, fast shifting, maximum precision, minimum play.
MONOLITHIC TECHNOPOLYMA SUPER AND BOTTOM SHAFT BODY WITH CARBON POWDER
Maximum lightness, maintaining resistance to shocks and weather conditions.
CARBON FIBRE CAGE
Carbon fibre cage: High rigidity for precise positioning - lowest weight.
