The Wolf Tooth 8-Bit Pack Pliers is a lightweight multi-tool with 17 functions your cant be without. Eight attachments nest inside the handles of master link pliers using magnets and a clever storage system. These attachments then fit into an 8mm ball detent swivel head that has a 4mm opening for hex bits, which adds functionality to the already-versatile master link pliers. This new multi-tool was created to solve almost any minor repair on MTB and road rides alike.   Features 17 functions: spoke wrench; valve core wrench; flat head #3.5 and Phillips #2 screwdriver bits; 2, 2.5, 3, 4, 5, 6, and 8mm hex; and T10, T25 Torx-compatible bits; install and remove master links; clear tire sealant clogs from valve stem; tighten valve stem lock nut. Magnets keep all bits in place. Ball detent swivel head helps access hard-to-reach places. Handle doubles as breaker bar for extra torque when head is bent. 8mm hex bit tested to over 40 Nm torque.   Compatibility Pliers works with 9-, 10-, 11- and 12-speed master links and chains (not compatible with Campagnolo 12-speed chains).
