Hah, on the topic of component durability, my Wizard with 9 speed Chorus Ergopower has developed a shifting problem in the lever requirign that you tap the "button" ever so slightly after each shift to a larger cog in order to re-center the rear mech over the cog. The lever internals (ratcheted drum) will not return to the detent otherwise. I suspect this is inadequate spring tension. The bike is less than a year old and has probably 600 miles on it.
Quality ain't what it used to be. My vintage bikes are shifting away just fine.
