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.
