At Rivendell they sell something which they claim to be the greatest friction shifter of all time. It was made by Suntour and I believe they call it the power ratchet. It has an actual ratchet and pawl system and sells for $38.00. What was the vintage of this? I don't see it in "The dancing chain". How does this compare to Retro-friction devices?
