Will also fit PCS-1 (post 1996) and PCS-4-1, PCS-4-2, and PCS-4 Repair Stands when used with the adjustable height extension. Park Tool TS-25 Repair Stand-Mounted Bicycle Wheel Truing Stand Small, lightweight, and accurate, the TS-25 Repair Stand-Mounted Wheel Truing Stand securely holds any wheel using a quick release or threaded axle and adjusts for any wheel diameter and rim width. Installs and removes quickly and easily. Perfect for making quick truing adjustments in situations where bringing a full-sized truing stand is not possible or practical. NOTE: For thru axle hubs, it is necessary to also use the TS-TA Thru Axle Adaptor to take the place of the quick release skewer.
