I am working on in unfamiliar territory. One of my student clients bought what he thought was a really good deal on a bike with LOTS of campy components on it. It seems to be in really good condition with wear but not too much on the chainrings and cassette. But the biggest issue is that the Left shifter arm has broken off. He paid $550 for it.
This young fellow wants to ride on the racing team here at UCSC (his first attempt at racing, and it is a small team, welcoming all) and doesn't have the $$ for me to buy and replace the Campy left shifter. Is there any reason (other than esthetics and asymmetry) that I can not put on a STI left shifter to replace the Campy Record (Carbon BB system) shifter? Is there any compatibility issue with the front derailleur. I cannot image that there is, but just asking.

I have found an appropriate shifter "body" from an outfit in Spain. Is it difficult to replace the body (the brake lever and hood are in good condition)?

I know these are two separate questions, but I would like to try and get a matching component for him. There is one for sale on EBay for $100 but even that is too much for him at this point.

Photos of bike here, but I don't have good ones of the shifter at the moment. Will upload tomorrow.

Bike hasn't been cleaned yet.













You can see the missing shifting lever on the left shifter here.



Broken shift lever, not a good photo will post another later

That part of the lever (shift paddle) is readily available and easy to replace. A STI shifter will work fine as well as it only runs the Front Derailleur if you choose to go that route. I have many of these in parts and rebuild them for friends occasionally.

Well aesthetics are already out the window with mismatched brakes and wheels. I don’t think there would be any issue using a Shimano left hand shifter. The small paddle is a little more challenging to replace than the big blade but it is user serviceable. It’s been a while since I’ve rebuilt an Ergo shifter and I can’t remember if you have to take apart the spring mechanism to get at it; if so it increases the complexity. On the Paceline forums, there is a nice guy OldPotatoe user name, lives in Boulder, who rebuilds Ergo shifters and I’m sure he could get that done at a reasonable price if you want to go that route.

As an aside, with all the mismatched front end and broken shifter, I’d inspect very closely for cracks around the head tube and make sure to remove the fork and inspect the steerer closely for any damage.

Are you referring to the entire shift assembly that looks something like this:



If so, that's a piece of cake to replace. Replacing just the thumb lever is harder.

Shifter compatibility isn't much of an issue for double chainring setups. You might get less than ideal trim options and lever feel, but you'd be able to make it work. The nice thing about this generation of Campy shifters is that the front uses a micro-ratcheting mechanism rather than indexing, so you can put the derailleur any place you want it. Makes it easy to use with a triple too. There may be some lower level models (Mirage, Xenon, maybe Veloce) that don't do that. The newer Potenza/Centaur/Veloce shifters don't work that way.

That's an 11S assembly.

Brake lever nor hood will fit.

Thanks Mackers, it didn't look right.

Hi Daviddavie,
Could you point me to the shift paddle source? I haven't found one. i think that the shifter is broken though. With limited toggle on that itsy bitsy remnant of a paddle, I cant tell if the shifter is actually pulling cable. Another member has pointed out that the ratcheting mechanism on this shifters is kinda unique and desireable. so I would like to try and see if I can repair it. Another member mentioned that STI will work as well as you, so I will go that route if I cannot get this one to work.
Thanks!

Hi,
Someone mentioned that this is a hood for an 11 speed and that it won't fit. It doesn't look like the mech that I saw also.
thanks

Nubra 

Good point about the esthetics. I did a pretty good inspection because it is carbon, but thanks for pointing me towards pulling the fork and taking an inside look at the steer tube, as well as sending me to other info sources.
Cheers,

Yeah, sorry, I just picked a random image. What I meant to show was the general assembly. There are three generations, easily distinguished by their shape if you know what to look for. If you have the right one, switching the hoods and blade over is easy.

I don't know if I would say unique as they are just Campagnolo Record brand shifters of that era and are built and work slightly different than another brand as well as being completely rebuildable (which others are not)

The part number is EC-RE329 . You can find them around the internet with a little looking. I seen them on a few sites including the USA and sell for about $60. Another option is get a broken used shifter and tear it down for the part you need so you will become familiar with how they are put together. This will make reassembly easier for your good one when/if the time comes. This part was used from 1999-2008 on the Record shifter but a Chorus one would work as well but they have a cut out in the paddle portion.

IMO if you do decide to rebuild I would suggest a spring kit also as they are cheap and will make the shifters perform as new. The right shifters will loose the ability to hold a gear and slip when the get high milage on them.
