T47 Outboard Bottom Bracket for 30mm Shimano Spindles with ABEC-3 Bearings

T47 Outboard threaded bottom brackets are made from machined aluminum, and thread together directly into T47 frames. Cups have outboard bearings, and are typically used in BB shells with widths from 68mm to 100mm.

• Enduro Angular Contact bearings - 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
• Compatible with 30mm spindle diameter cranksets
