Although Russ has come to the defense of Campagnolo over Simplex, I still find fault in his condemnation of the fine vintage Campy Valentino derailleur. Being a poor teenager at the time, having graduated from high school in 1971, I tried my luck with two inexpensive racers. My first was a Peugeot UO8, which I know list members are tired of hearing me denigrate. My second was an Atala of similar original list price. There you have the perfect taste test of the early 70's. A competition without prejudice, between France's entry level racer and Italy's. The worst Simplex rear deraileur was incapable of a shift and the lever had the fine feel of drinking a soda out of a pop top can. (If you don't cut your hand with the act of removing the peel off top, you bruise your lip with the sharp edge that is left behind--- surely the Simplex lever was designed by the same engineer and manufactured side by side in the same factory). The plastic deraileur not only was non functional but had the added aesthetic appeal of cheapness that has come to represent the worst of the newly expanding world of 70's plastic. Now let us examine the Valentino front deraileur which to me is more appealing than any other I have ever seen. The rod emerges from a mysterious yet attractive box which wisely protects the mechanism from grit and dirt. (a feature that is missing from even the finest modern mechanisms). The rear was a pleasant upgrade from the Simplex and was actually quite effective, or at least much more so than the dreaded French Simplex, the destroyer of freewheeling dreams. If a company can not be judged by its cheapest entries in the market, then should we only examine the top of the line to make our comparisons? In this regard the Campy offering was a poor man's cycling salvation, and many thanks to Saint Tulio. As to Simplex, I can only say the same thing that the French students sang to President DeGaul: Adieu! Adieu! ( Goodbye forever, rather than Aureviour which is Goodbye until next time.) Garth, PX10's are better off with Campy than Simplex, Libre.
