I have a Campagnolo 10 speed front derailleur that shed a part while riding and I'm looking for a spare part or fix. It is the rear part of the cage which screws into the inner cage and connects the front carbon cage with the rear metal cage. It doesn't appear to be a Campy spare part that they sell according to Campagnolo catalogs.

Does anyone know if this part is available and if not, maybe a DIY fix? The cage seems like it's spread open now and I'm afraid the carbon will break without the support of the missing piece.

Many thanks, pics below to show what I'm talking about:

It's been a while, so please take this with a grain of salt.

If memory serves this was integral with the inside surface of the outer cage plate and part of the steel system that keeps the chain from cutting into the carbon as you shift.

I have to wonder if you've been dragging the chain against the cage, which is fairly common with poor trim, and over time sawed through the steel.

In any case, you'll have to either find this part in a dealer scrap heap, or fabricate it from a piece of stainless and then bond it to the outer cage plate.

IMO, you're likely best bet is replacing the entire cage if you can find one or replacing the derailleur.

Yep. Chains saw through early SRAM Red titanium cages, too.

No surprise, really. Aluminum oxide is an abrasive. Add a little to chain lube - say, from normal wear of an alloy chainring - and you have a mild grinding paste.

Many thanks to all for the help and very helpful links, I appreciate it!



No dragging or other strange habits going on. However, my FD shifting has never been that great but this is first and only index shifting I've ever had so nothing to compare it to. Of course, that's mostly when shifting to the big chainring where the lever needs two or three swipes to complete the move. And then to the small chainring, it's pretty easy and that is where the outer carbon cage comes into play.

Also, I don't believe there is any metal to the outer cage; it's all carbon with a plastic, replaceable insert that rubs on the chain.



Thanks so much for that first link. Very helpful and within that thread, they link to this:

In this weightweenies thread, a guy repairs his FD using a bit of old spoke so I guess I'll give that a try as the supply of 10 speed FDs has dried up; not many out there.

Also, why wouldn't campagnolo make this small part available? Or make a metal version?

Here's the spare parts catalog for the 10 speed carbon FD:

And again, many thanks....

35mm seat tube? You can find new and used fronts, you won't like the carbon tax, but a veloce/daytona/centaur/chorus, or something in that range should be doable. I dare say a 11spd athena would probably work also.

For now I'm going with the weightweenie DIY fix. Here's my preliminary fitment of the spoke fix. I have to say the use of a spoke works perfectly!
Still need to order some wire to wrap it up and epoxy to glue it all together.

I would mimic the original part so you can access the screw.

Part of the problem may be the obvious lack of maintenance.

tNuvolari

Yeah, it does look dirty but chain was cleaned and lubed less than 1000 miles ago.

It's a dirty world out there!

Bike is well maintained but just because I don't spend my Saturday nights cleaning chains, it doesn't mean the bike is falling apart. And the problem that happened with the derailleur disintegrating is obviously a design issue and not a maintenance issue. Many have had this problem and Campy redesigned their FDs after the 10 speed groupo to completely eliminate the plastic piece that breaks off.

Of course, with logic like your's, part of the problem may be anything from my drinking to the rotation of the earth!

smd4

You've got way, WAY too much lube on the outside of your chain, which has picked up a ton of excess grit, no doubt contributing to the destructive and abrasive action that helped lead to your derailleur failure. It will also lead to the premature failure of several other parts of your bike.

Logic.

You'd think people would take better care of their things. Especially the expensive kind.

tNuvolari

Ok, did the fix and cleaned it all up so hopefully smd4 will shut the hell up now. I have to say that with the stiffer metal connection, the FD works much better and faster now. I would recommend others do this mod before their plastic bit fails.
Mine is not the prettiest but it works. I'm not sure how much stress this part experiences and I didn't want to have to fix it again if it failed so I went overboard with the wire and epoxy. But it works and it's stiffer so I'm happy. And it's better in real life....I swear. It's not very noticeable.

You’re welcome.

Just find a Chorus FD and be done with it.

agree, you can find a Chorus unit and just swap the cage (which is titanium) over onto the existing clamp.
