Some people think that derailleurs are a modern invention, while others think they’ve been around in their current form as long as the “safety” bicycle frame has. Of course neither is true—the modern derailleur is the result of a century’s worth of engineering and experimenting. This Dutch website (translated by Google Language Tools) provides a pictorial history of the derailleur.
That’s one nice looking “Pie Plate” on that wheel.
“Tuning is simple. The Jagged bus where the chain suits you can distort, and thereby shifting the conduction and screw your derailleur among the highest gear.”
i’ll have to try that!!!
