T47 threaded BB cups for T47 frames and 24.00mm spindle diameter cranks. Cups have internal bearings, and are typically used in BB shells with widths wider than 73mm. Machined aluminum cups thread together directly into a T47 BB shell. Bearings are easily serviced or replaced. Includes sleeve to fit between cups for added protection from dirt and grime, and also keeps your internal wires and hoses from rubbing on the crank spindle.T47 BB cups are similar to standard BSA threaded cups in that the drive side cup is left-hand thread and the non-drive side cup is right-hand thread.SPECIFICATIONBearings: Enduro Angular ContactColor: BlackBottom Bracket/Frame Interface: T47Bottom Bracket Shell Width (mm): 68mm - 132mmBottom Bracket Shell I.D.: 47x1.0mm ThreadedCrank Spindle Diameter: 24.00mmOver Bearing Width: 91.5mm in 86.5mm wide shell*Tool Pattern: 48.5mm x 16-notchWeight: 119g
