Spoke wrench

Our iconic spoke wrenches have been a staple of our product line since we introduced them over 50 years ago. With their simple design and professional quality, they continue to be favorites of bicycle mechanics worldwide. Each Park Tool SW-0 is manufactured in the USA, and is heat-treated and nickel-plated for long service. Park Tool spoke wrenches are vinyl-coated for at-a-glance sizing.

The Park Tool SW-40 uses the same world-famous design and high-quality materials as our three-sided spoke wrenches, with a unique four-sided wrench design for greater strength and support to help prevent slipping and deforming nipples. Each SW-40 is manufactured in the USA, and is heat-treated and nickel-plated for long service. Park Tool spoke wrenches are vinyl-coated for at-a-glance sizing.
