Is this long-cage Campagnolo RD done?
Was given this deraileur and was thinking of installing it. It is unusable?

That stop screw is there to limit the movement of the cage so it doesn't unwind the spring. It doesn't come into play at all when the derailer is mounted because the chain will do the same thing. The screw will never hit the stop because the chain won't let it go that far. That's a first generation Rally. I'm using one. It's not bad.

incazzare.
That's a bummer.
You could install it on a bike in the workstand and just test it out and see what happens.

Agree with BG. It would only be an issue if the chain does not limit the rotation. If that were the case then you chain is the wrong length. It might fail when/while the rear wheel is removed.

+1, or another vote with GB (edited due to Friday dyslexia)

I think you guys meant GB, not BG (which we sometimes use for Bianchigirll).

You might just be able to use a chain with one link removed from ideal. You'd have more combinations that would be "illegal" though. I'd try it also.

You can also buy a beat up Campy NR RD, hopefully for cheap, and harvest that part from it to replace the broken one......
It's not that hard to replace. In fact, I'd prefer that than just riding it with that damage, as the stop screw might eventually fall out and get lost or..............jam into your chain, which will tangle up on your freewheel, stop your wheel instantly, blow up your tire, send you out of control, downhill at 30mph towards a road barrier and catapult you 20 feet into the air with your bike off a 1000 foot cliff on the other side and your bike and bones will not be discovered till another 23 and a half years by a hiker and his dog looking for mushrooms.........

Wow, Chombi! You sure know how to soft-peddle a convincing argument. Do you seriously think that any of that might happen? I agree with you about trying to find a cheap donor part and combining the two to make a sound derailleur. But, the likelihood of finding one cheap is pretty slim. If that's the plan, I'd wait until winter when the parts are closer to half what they're worth now, at the peak...

One can also just take out the stop screw and set it aside till a replacement lower pivot piece is found and installed. As already noted, the stop screw is not really needed while riding the bike, but it does come in handly when you have to pull the rear wheel off, as it will let the pulley cage spin up too much and you might end up with a tangled mess with your chain. At least the OP will also not have to think about it dangling out of that cracked piece and possibly getting lost.

I did exactly that on one of my Rallies. It's an easy transplant. You can also get that piece on eBay sometimes for like $10. Until then, just remove the stop screw.
