Rotor Round Spidering noQ 46 / 30t Direct Mount Chainrings combines a 46t outer chainring with a 30t inner chainring, fixed to a spider for direct mounting to the crank. Spider ing is compatible with ROTOR’s 3D +, 3D30 and FLOW cranks, as well as the INpower 3D +, 3D30 and Flow potentiometers. The spider bonding eliminates frame interference that can occur on 30 inner chainrings when mounted with chainrings. They are manufactured with a 7075-T6 CNC machined structure reinforced with a High Module Carbon 3k finish and with a design that increases rigidity. They are also designed to be compatible with all 9, 10 and 11 speed groups.
