The Bottom Bracket Buddy System (BBBS) is for the vise and the frame builder. Now you don’t have to have brass or aluminum shoulders on your vise. BBBS is the most simple, yet effective tool for your frame building needs.
Hold your frame in the vise with NO SLIP CONFIDENCE™ and serialize with a great shoulder to rest on inside the BB. This is the one tool you had years ago.
Sizes: BSA / PF30 & T47 / BB30
