Description:

This thin ratchet was designed to turn spoke nipples on bicycle wheels. The head and frame have open notches to allow the wrench to slide on from the side, and the notch in the head tapers to fit different sides of spoke nipples. The ratchet pawl has a handle so that it can be disengaged to allow the ratchet head to rotate freely to position it.
