Sapim 4.20 mm Spoke Wrench

Sapim’s 4.20 mm spoke wrench is a professional grade spoke wrench manufactured by Unior from forged carbon steel. The four-sided wrench is perfectly designed for Sapim’s 13 and 14 gauge Oversized Nipples, which measure about 4.1 mm across the wrench flats. It has a light ergonomic construction, with a plastic dipped handle for excellent grip. The narrow profile of the wrench makes it particularly well suited to high spoke count wheels, such as e-bikes or small rimmed wheels where there is a short distance between each rim hole.
