Nova Ride Carbon Ceramic bracket for Shimano GRX 812/817, 11 Speed, red
Carbon arms with a wall thickness of 3 mm ensure the maximum possible torsional rigidity 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 as well as friction are minimized, which makes it possible to save 4-6 watts compared to a standard chainring. 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 feature high-precision ceramic balls as well as ceramic raceways made of silicon nitride. The main advantages of all-ceramic 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. The crash replacement program ensures the possibility of exchanging a damaged arm at the importer for a new one with a 50% discount from the selling price.
