SUPER RECORD REAR DERAILLEUR
Speed, precision, smoothness and better looks: the first rear derailleur with carbon fibre upper and lower body will amaze even the most demanding of cyclists.
FEATURES & BENEFITS
COMPLETELY NEW DESIGN - The new shape of the external components enables the rear derailleur to move according to a different angle and the new internal design keeps the chain nearer the cassette to ensure better power transmission, greater and more secure traction, a better chain/sprocket interface and greater durability of components subject to wear and tear.
EMBRACE TECHNOLOGY™ - The special chainring positioned inside the gear body acts on a rectangular section spring that allows the component to move along a trajectory that perfectly follows the curve of the sprockets, on both the 11-23 cassette and the new 11-29.
ALUMINUM FIXING BOLT - The new two-part system is 53% lighter than steel and 22% lighter than titanium, without compromising resistance and rigidity levels and prolonging component life.
UPPER AND LOWER BODY IN MONOLITHIC TECHNOPOLYMER WITH CARBON POWDER - maximum lightness yet still resistance to knocks and the elements
CARBON FIBER CAGE PLATE - Shifting positioning is exceedingly precise - extremely light.
CARBON FIBER PARALLELOGRAM, AND EXCLUSIVE ULTRA-SHIFT™ GEOMETRY - Maximum shifting rigidity, fast actuation, precision, friction reduction
CERAMIC BALL BEARINGS - Very smooth, reduces friction, prolongs life and shifting performance.
PULLEY CAGE ALUMINUM FIXING BOLTS - Lighter.
Weight: 166 g
Note: the medium cage derailler RD18-SR1M is required for use with the Campagnolo 11-32 cassette
