Park Tool Truing Stand Upright Extension

Park's Truing Stand Upright Extension installs in seconds to your TS-2 Professional Truing Stand. It allows the stand to be used on wheels with hubs up to 160mm wide (tandems and downhill bikes), as well as 29-inch mountain bike wheels. Plus, specially sized bosses on the TS-2EXT serve as adaptors so it can be used on wheels that use 20mm through-axle hubs.
