On the contrary. They are great at high RPM,
ON A RECUMBENT. Since I'm a spinner, I could never use them on an upright.
My fastest 'bent has a 20" drive wheel, and a 12/44 high gear. (70 gear inches) With it's 153mm cranks I can maintain 27mph. However, these old legs are power limited, so I need a slight down hill or a good tailwind to hold that speed for any length of time.
