Question for the Campy whisperers...

Mark McM's backward trick addresses this - accomplishes the same thing as a nut.

Wolftooth sells the screw!

recently i was going through the campy 12 speed documentation for my own build and i recall reading the first production run rear mechs were designed for 32t cassettes before changing something and officially making them accept 34t cassettes. i was reading up on record and i think SR was the same. there is some code on the derailleur that signifies the change but i can't remember beyond that

Yea, I found mine in one of the metric hardware drawers at lowe's and was not only surprised to find one that fit, but it was also loose in the back of the drawer and there weren't any multi-packs to purchase. I confirmed fit by threading it onto the B screw that I brought with me and tossed it in my pocket....shhh don't tell anyone!

I bought some other stuff that I needed so I won't feel too guilty about absconding with that .02 micro nut
