The Pedro's Pro BB Socket Cup is the reusable body at the centre of the Pro BB system. Add the insert that matches your bottom bracket and you can expand the system as your bikes change, instead of buying another complete socket each time.
This SKU is the cup only. Inserts and the Pro BB Socket Holder are sold separately. The machined 7075-T6 aluminium cup accepts a 3/8-inch square drive or a 24mm spanner, while its internal M12 thread connects to the holder when controlled engagement is needed.
