I've used a lot of lip fenders. Side stand, clamp, better grip etc. I had high hopes for them as the weight is minimal and everything is easy. This saves space and the weight of the other two irons. They broke the bead on my 150/70-17 Heidenau K60 (F800GSA). It took several times with the cord but it broke after three attempts. Much faster, simpler and easier than any other method. I've heard complaints about the angle of the iron but they worked great. It took me a total of 20 minutes to remove and swap out my K60. Use your knees! Check out the BestRest video, it saved me a lot of time. I love Movement Pro.
