A Pro BB Insert gives your Pedro's Pro BB Socket Cup the profile needed for a particular bottom bracket. Choose by the cup's notch pattern and tool diameter, rather than the bike brand or axle size alone.
The heat-treated steel insert locates in the cup magnetically, so you can exchange profiles as you work on different bikes. This listing supplies the selected insert only: you also need the Pro BB Socket Cup. Check the exact bottom bracket against Pedro's compatibility chart before ordering.
