T47 Inboard threaded bottom brackets are made from machined aluminum, and thread together directly into T47 frames. Cups have internal bearings for use in BB shell widths from 68mm to 132mm.

• High quality Enduro bearings can be easily serviced or replaced
• Similar to standard BSA threaded cups; the drive side cup is left-hand thread and the non-drive side cup is right-hand thread
• Designed to fit 29mm spindles on SRAM DUB cranks
• Included sleeve fits between cups for added protection, and keeps internal wires from rubbing the crank spindle
