Our iconic spoke wrenches have been a mainstay of our product lineup since we introduced them over 40 years ago. With their simple design and professional quality, they're still the favorite of bike mechanics around the world. Each Park Tool SW-0 is made in the USA, and is precision-stamped, hardened and nickel plated for long service. Park Tool spoke wrenches are vinyl dipped to indicate the size at a glance.
