This is the Park Tool Upright Extensions & Thru Axle Adapter. The TS-2EXT.2 Truing Stand Upright Extensions install in seconds on any TS-2 Truing Stand, allowing the stand to be used on wheels with hubs up to 200mm wide (tandem, fat and downhill bikes), as well as on wheels with a 29” mountain bike tire installed. Additionally, specially sized bosses on the TS-2EXT.2 serve as adapters so the TS-2 Truing Stand can be used with wheels using 12mm, 15mm, 20mm or 25mm thru-axle hubs with removable axles.
