I see they have reversed the collet in their setup. Too bad it looks like they have stuck with the wimpy 1/2-20 threads on the unit. That was my only beef with their setup because the threads stretched. I had to keep a 1/2-20 tap and die in my toolbox to fix those collets. It's OK tho, I have everything switched over to the Zipp Kits Super Collet and have nomo problems at all!!! Brian
