Pedro's Pro BB Socket Insert - Shimano 16x44
This is a single 16-notch x 44mm insert for Pedro's Pro BB Socket System. The system uses one aluminium Pro BB Socket Cup with interchangeable tool steel inserts, so you only buy the interfaces you need instead of a full socket for every bottom bracket standard.
The insert clicks into the cup and is held magnetically, so swapping between standards is quick. Used with the cup, it can be driven by a 3/8in torque wrench, the Pedro's Pro Socket Handle or a pedal wrench, and the cup's M12 thread accepts the Pro BB Socket Holder to stop the tool slipping.
