Ervaringen met de Snoek/Snoek-L

[PieterTrapt]

Dit lees ik op Reddit: 

Shimano actually did a huge amount of biometric research on them, but people today talk as though they just randomly chose a shape and it's the opposite to what's 'correct'.

The truth is it depends on your pedaling style and taste. They were popular with cycle tourists more than any other group of riders. Biopace is designed more to reduce stress on knees than improve pedaling efficiency or power. That's what led to it's poor reputation in competitive road cycling.

The opposite orientation of ovalised chainrings as used by Rotor can theoretically increase pedaling power but has a potential drawback of a 'whiplash' effect - to quote Sheldon Brown: "the low gear when the cranks are vertical means that the knees are moving extra fast when they are changing direction from going up to down and vice versa. This "whiplash" effect caused most users to abandon elliptical chainwheels. Ever since the chain driven bicycle was invented, elliptical chainwheels have been re-invented and re-abandoned for the same reason every ten or fifteen years."

Die laatste zin is mooi: "Ever since the chain driven bicycle was invented, elliptical chainwheels have been re-invented and re-abandoned for the same reason every ten or fifteen years."

Maar ik ben heel benieuwd naar praktijkervaringen. De mijne (met Biopace, dus niet met Rotor) waren neutraal.
