Hi Bulgie

Thank you for the explanation. I will try to explain as well as possible in English.

Your Rally looks great with the titanium bolts, your model looks a little different with the Record letters on it, is it modified with parts from other campagnolo models?

First, I have read and seen pictures online that the difference between the two is: the reinforcement at the back, (the one without is the oldest, as you also mention) and then I can see that the oldest has campagnolo letters on the back and has numbers engravedon the arm, the new one doesn't have it. Thats the only things I know.

The "newest" model of the two rally´s, I know it has never been taken apart, as it has been sitting on a one owner bike from 1983 that has been in a garage for 40 years.
- It feels right and have a great tension / pre-load.

The slightly older model I had bought second hand, and I thought the angle of the arm looked a little wrong, without being an expert, but I bought it anyway. I don't know the history, so it may very well have been taken apart over the years.

I just tried to take it apart. It feels like it have to much pressure / load compared to the other rally, although the arm does not turn all the way down as it should, if I move it more forwards its very hard, I think the arm with the spring has been turned to much around or 1-1˝ turn? Otherwise it totally loose, but still not in the right position.

I tried to change it in the hole, and it does not help. I can't get the arm to turn downwards and fit the correct place where the stop-screw is.
The arm has a lot of pre-load, or otherwise is complety loose.. The spring looks i bit worn out??
