I spent some time today with the Giro build figuring out what to do next...what bar tape to use...what tires to buy...what color housing to choose.

As I fiddled with the front derailleur and noticing some grime and dirt on it I started cleaning and removing the limit screws. That was until i heard something snap. The limit screw broke off with half the screw still inside.

Another bonehead move I took it apart but couldn't get a clear path use needle nose pliers to attempt extracting the screw.

Well now its 20 minutes later and the screw is out but the threads are stripped and im pretty sure ive committed homocide. No longer does the derailleur have threads to hold new limit screws.

A question i have is if the front cage, bolts, screws and cage are of some value to others.

A moment of silence please........




Thank you.

It does seem like it does all come apart easily but getting the threads redone or chased seems a bit pricey.

I always find it easier to replace a broken part than attempt to fix.

Nearest vintage bike shop is pretty far off and pricey to begin with. I may just buy another.

I fix things. That is what I do as it is fun. You may not like fixing stuff so buy a replacement. They are cheap to be had.

FWIW, you're not the only person around here that occasionally learns by breaking. Trust me on this.

Don't throw the baby out with the bathwater. Is it a clamp-on or braze-on fitting? I has sparez

Im completely comfortable posting on here when I break something and know very well im not alone. I knew when i tried extracting the broken piece of screw there was a chance of me breaking it even more

Clamp on but I'm not fixing the derailleur. Just picking another one up tomorrow.

Is it really Super Record?

Nope

Don't the SR FDs have TI bits on them? Thise could be worth something....

Glad to know that there are others. I still manage to create a boo boo or two, even after all these years. Should have seen the Shimano 600 cable adjusting screws I removed from my son's Empire Professional, the other day. Stripped both and then went to the small parts stash (if you don't have a small parts stash, start one - they seem to grow all by themselves, over the years, and prove to be incredibly useful) for replacements. Got lucky and the Pro is good to go...


Good advice accompanies this thought - always ensure that the threads are greased, more so when one is alloy and the other steel. Anyway, my boy's bike and it is not bad for a city junker, in my opinion...

Nope.

Use a lock nut and bolt of the same thread to set the hanger travel stop. If not enough space go for a different TPI thread or even imperial/Raleigh thread and cut a new thread in the Al body as you go to the sweet spot. It just means get the adjustment correct the first time you wrench it home.

No, the only difference between the Record and Super Record front derailluers is that the arms of the Super Record were anodized black.

The Super Record rear derailleur does have titanium upper and lower pivot bolts and a slightly different pulley cage than the Nuovo Record.

Is that supposed to be a response to my post?

Yes. You have a stripped M 3 mm thread in Aluminium. A 1/8 imperial bolt should track down tight. If not a imperial tap will. Failing that a nut on both sides of the stripped housing will secure a M3 bolt at the correct depth for correct chain positioning.
What have you got to lose.

I have a stripped thread not grand bois

You can buy a tap for less than $10. It's not that hard to redo the threads.

Going thru all my options and suggestions its easiest to just get another derailleur. Its not just the threads that needs chasing but the opening has widened.

Yes I'm well aware this is an SR FD

I said NOPE because Grand Bois originally asked if this was the derailleur called the Campagnolo Rally

No rude attitude. Cant understand how you read my reply in that type of tone.

I didnt see his correction.
