This device quickly pushes down through stems/spacers/upper headset to keep everything in place when servicing headsets or replacing forks. No more using toe-straps to affix handlebars on top tubes. Quit kinking your client’s cable housing and hydraulic lines! Stop putting grooves in their handlebar tape! Why risk chipped paint, dented aluminum, and frame-destroying carbon impacts? EVT shops do not damage their client’s property. (At least not without their express permission.) Comes in silver or red, for all threadless 1 1/8″ upper headset bearing assemblies.
