The Park Tool TS-25 Repair Stand-Mounted Wheel Truing Stand is a handy accessory for making quick truing adjustments in situations where bringing a full-sized truing stand is not practical or possible. The PRS-25 installs easily onto the top tube and upright of select Park Tool portable repair stands and can be used while a bike is installed in the repair stand. Securely holds any quick release or solid axle wheel and adjusts for any wheel diameter and rim width.
