Park Tool Truing Stand Upright Extension

Park's Truing Stand Upright Extensions are made of durable chrome-plated steel and have quick-releases so they install in seconds to your Park TS-2 Professional Truing Stand (sold separately). The Uprights allow the stand to be used with wheels with hubs up to 160mm wide (found on some tandems and downhill bikes), and 29-inch mountain-bike wheels. Plus, there are specially sized bosses that act as adapters to hold wheels with 20mm through-axle hubs, too.
