    Bottom Bracket Socket

    Rather than using a bottom bracket wrench that could pose a risk of scratching or damaging your BB cups, pick up a Birzman Bottom Bracket Socket for a no-slip fit that's compatible with torque wrenches. This 1/2in drive socket is made of hardened steel for durability, and is CNC-machined for a precise fit. It works with Shimano Hollowtech II style bottom bracket cups, as well as any other cups with a 44mm diameter and 16-notches, which tends to be the most common type among external threaded bottom brackets.
