About This Product: Crupi Rhythm Pro Select Crankset-Black

The Crupi Rhythm Pro Select Cranks-Black at J&R Bicycles are high-quality cranks built for max strength with minimal weight added to your drivetrain. These cranks are designed with hollow cold-forged aluminum alloy arms to deliver lightweight strength with added rigidity for super stiff responsiveness. The 10-spline spindle is made from heat-treated chromoly alloy for increased durability and is compatible with most BB shell types. Made with a removable spider that works with 104 BCD chainrings (chainring is not included) the Rhythm Pro Select Cranks require an EB24 (BSA24) sealed bearing bottom bracket (sold separately). The included pedal washers must be used at all times.
