All three belts replaced. A drive belt came off the pulleys and all three were overstretched. I followed the excellent step-by-step detailed YouTube video Astorad2000 22m53s to change the belts. My CX-300 is now tapered, straps are only $12. The photos show an old drive belt without rollers and a newly installed drive belt.
