Nova Ride Carbon Ceramic derailleur cage for Shimano Dura Ace/Ultegra, 11-speed, gold
Nova Ride Carbon Ceramic derailleur arm for Shimano Dura Ace/Ultegra
Carbon arms with a wall thickness of 3 mm ensure the maximum possible torsional stiffness when changing gears. Thanks to the upper 14-tooth and lower 17-tooth pulley, when the chain passes through the pulleys , its movement is optimized and bending and friction are minimized , which makes it possible to save 4-6 watts compared to a standard chain . Both color anodized pulleys are made of solid duralumin alloy AL7075 and fitted with all-ceramic bearings with minimal rolling resistance that do not require any special maintenance or lubrication!All-ceramic bearings have high-precision ceramic balls as well as ceramic raceways made of silicon nitride . The main advantages of these bearings compared to standard bearings are their longer service life, lower weight, greater strength, lower rolling resistance and excellent anti-corrosion properties. Their weight is about 60% lower , while they are 7 times stronger compared to steel balls . The gasket used minimizes friction and protects the bearing against the ingress of dirt.
