Our External Bottom Bracket tool is just another example of Straitline innovation. Currently the tool available is simply a wrench. Have you ever noticed there is a torque specification for external BB's, if so how is it achieved?

Now it is simple with our 1/2" drive External Bottom Bracket Socket. Simply put on 1/2" torque wrench and tighten to spec'd torque. Fits most Ext. BB's.

The External Bottom Bracket tool is made of 6061 T6 Aluminum, machined and anodized red for high visibility on your workbench.
