Review on Park Tool Accessory Collar Work by Christopher Smith

This clamp did not fit my Park PCS-1 stand without significant modification. The diameter was too small to attach the tube. When I contacted Park Tools they told me they had redesigned the PCS-1 stand and the clamp did not fit the old stands. The Revain add-on doesn't mention this small detail. I got it working, but first I had to cut out about 1/8 inch of the material. Luckily he was pretty strong in the beginning so he's still holding out. The park's website states that it will only be eligible for PCS booth 1 after a certain date.
