#climbing auto-belay devices tested, courtesy of HowNOT2.Amazed with that centrifugal brake design. It's really clever, simple and effective. Centrifugal clutches on motorbikes operate pretty much with the exact same principle using brake pad materials and rotation speed. I've always wondered how some of those auto-belay things worked internally.I also think that centrifugal design is more serviceable if needed.https://youtu.be/Z97RkAapbDE?si=awOOGQlh4jtaPY7z
