I am neurotic enough yet. I actually forgot what i came in to type but, hopefully this pic will suffice. Got these in the mail today, going to polish them up and try to recoup some money. OH NOW I REMEMBER. on the 50th, I removed all the set screw springs on the Campy derailleurs, which allowed me to tighten down clamp, further without crushing the springs, the set screws. It is permanently entombed in one gear. NO SCRATCHES, no chance for shifting. no chance of chain ever getting to intimately know the rear triangle frame.. When my son or Grand son sell it for $25, they will be searching the BAY, that with an E in front, for derailleur set screw springs. Screw them LOL
