Hello! I found an incredible deal, and I plan to buy some aluminium shifters and derailleurs (I do not want non-metal ones). The price is so good that I want to stock on some parts, as I know the disaster that strikes when your drivetrain is no longer supported by Campagnolo. I have already chosen the levers, but... The main question is...which derailleurs, front and rear. My second question is about compatibility with BB and chainset, as I am upgrading from a mix of Chorus 9 and 10 speed.
The all-silver shifters are Athena EP15-AT1C. I plan to use low gears (knee injuries will make you go from a lazy masher to a remarkable cadence rider). I quite like the new Centaur 12-32, as I rarely use my 13T anyway, and the new cassette will give me another higher gear, when in the small ring. I have two options for a RD, and their price is the same.
I can get either the triple, long cage RD13-ATB13 that *could* clear the 32T (I have 425mm chainstays on my CX frame), or the medium cage Potenza RD17-POS1M. While the Potenza one can definitely clear the 32T cog... I agree with some users claiming that Campagnolo should not offer midrange components with so much plastics in it - and I also do not like the aesthetics, it is just plain fugly. With the Athena long cage I have no guarantee that the 32T will work fine.
What worries me the most is that the pull ratio change took place in 2015 - and the 2015 Athena shifters might not be compatible with the 2013 Athena RD. On the other hand, Campagnolo claims that Potenza is not cross-compatible with other groupsets.
The front mech I found is Athena FD12-ATB2B. I am not sure if it will work with the Athena 2015 shifters... I currently own two new FDs for 10 speed, Chorus CT that I use with all-Chorus 9 speed, and I`d like to use them. About BB and chainset...My frame required the 155.5 mm BB, as the Chorus 102mm one was too short and the inner chainring from the compact touched the frame. I use a square taper (no cups) carbon chainset and I like the simplicity of it. If it does not work fine with Athena 11, I could buy the Campagnolo CX or some other compact chainset, as I want to run a 46-34 one (I will event try the TA 33T chainring). Thanks for your time, much obliged - any help will be much appreciated.

Your lever choice pretty much dictates how this build will go. I have the 2013 version which is backwards compatible. If you stick with the 2015 levers, you will have to get the corresponding derailleurs. Potenza is a good option as it has the latest features from the higher groups & can be found online at good price. This might interest you:

That Enigma is a really cool build, but pricey.

A little update : The Velotech UK FAQ claims that Potenza and Athena are not compatible, but all Athena components from all years are suitable. It clearly says 2010-2015 too. Now I guess I must buy and try with the 12-32 cassette...

I just checked that site & are you sure you read correctly?? Hate to burst your bubble, so before you start spending....

Q: What are the compatibilities between 2009-14 mechanical systems and their 2015 counterparts?​
A: 2015 Front and Rear derailleurs and shift levers, ErgoPower or bar-end must be used in conjunction with each other. There is no compatibility between 2009-14 shifters and 2015 or later derailleurs.

For full function, 2015 gear shift systems should be used with 2015 crank sets as the spider and chainrings are designed to be much stiffer, facilitating a better upshift in combination with the redesigned 2015 FD cage and actuation.

Thank you, sir - like I stated in the original post, any help will be much appreciated. I checked the FAQ again. Just below your quote, we read:

" All Athena 11s components with the exeption of brake blocks and holders are completely compatible across the 2009-2014 / 2015 model years.
All Veloce 10s components are likewise, with the exeption of brake blocks and holders, completely compatible across the 2009-2014 / 2015 model years."
I guess this means I can use 2015 Athena levers with 2013 RD and 2012 FD?

The quote that you referred to, they were stating that the chains & cassettes are compatible with the exception of the 12-32 cassette. They can't guarantee that it will work with 2013 rear derailleurs depending on the frame geometry.

As I said before, I think Potenza is a nice groupset but its unique to itself. It has its own unique pull ratio making it non-compatible with any other groupset. Campy first started messing with lever pull ratios when they re-designed the front derailleur with the longer lever arm. This means that you have to be diligent in making sure that you have the correct year, matching parts for your groupset to work.

As for the crankset needing to be matched as well...that isn't quite true. The tolerances are such that there is plenty of leeway that you can get away with even a 10 speed crankset & the system will still shift fine without any hiccups like say a power meter. Wink wink D) Hope this clears it up for you.

I'm afraid these days, everything seems pricey. Electronic groupsets going for $3 to $4k. $7k for a new bike is the new norm???

I just wish that Campy was making alloy parts like they used to. Polished anodized that gleamed in the sunlight. I don't even know what to call the finish they presently use on their alloy parts. Brushed satin??? I guess if money is no object then you can get pretty much what you want.

Yes, Stan01, I agree. Everything is so damn pricey, especially lower end bikes, let alone carbon fibre junk. It is plain fugly and plasticky, no polymer for me, please - I am all metal. And being 92 kg is not exactly carbon-friendly. I would not buy Potenza for its plastic paddle, and DaveG was kind enough to point that his Athena shifts crisper, and is more similar to the old Campagnolo shifting style, while Potenza is a bit more like shimaNO. Having found a 11s YBN chain that costs just 16 EUR, I am determined to upgrade, as the chain cost was my main concern. I have used YBN 9s chains with good luck. And since the Centaur 11s cassette is not much more expensive than Veloce 9-10 speed cassettes, I decided to upgrade.

Hi everyone, many years ago, I built up my Ti road bike using 2013 Athena components. Recently, the rear shifter has started misbehaving, shifting down several gears at once. I think it's a broken spring carrier, as in this repair video:
. To repair it seems really difficult and tedious, and not guaranteed to fix what seems to be a design flaw. I think these are my options, in order of desirability:
1. Find an original 2013 right Athena (silver) brifter, or a pair, and replace my bad one. This option is pretty unlikely. There don't seem to be any left.
2. Find a compatible modern (likely post-2015) brifter pair and replace both. Hopefully, Campy fixed the spring carrier design problem post 2015, but I'm not sure. Would the current Centaur drifters work? I understand that the Potenzas won't.
3. Replace the drivetrain components with Potenza. I've already had to replace the Athena rear derailleur once already as it exploded on a long ride a few years ago. This is a costly option, but hopefully Potenza is more robust than Athena seems to have been.
What do you all think?

First off have you tried cleaning your levers?? They may be gummed up & the pawl inside is not catching causing it to jump down. Try spraying the innards with wd40 first very liberally to flush out any contaminants & then re-lube afterwards when dry. See if that helps.

If that doesn't help then your only option is to buy the replacement shifter body kit for that model year as those levers are non-repairable. Post 2015 Athena shifters have different cable pull ratios, so no good there. Potenza drivetrain only works with Potenza shifters only. I do not believe current Centaur 11spd is backwards compatible with 2013 Athena. Good luck.

Thanks for the suggestion. My levers are clean -they operate smoothly except for the big click when downshifting (i.e., upshifting to smaller cogs), which is the symptom for a broken spring carrier. For now, I'm considering a) buying a replacement lever kit, part EC-AT200 and waiting for it or the rear derailleur to break again, or b) switching the drivetrain to current Centaur components. But thanks for the suggestion.

I would suggest that you still try flushing out the lever first. I've owned shifters by all 3 brands & I've only experienced this type of problem with Sram & Campy. My Sram levers were doing exactly the same thing as you described, jumping gears on downshifts, but otherwise fine. Outwardly they looked fine. Flushing out the lever helped revive it back to normal. The internals get gunked up with dirty air & things no longer work properly. If you haven't done it before, I would suggest that you give it a try.

From experience, you should buy the shifter body kit. It basically gives you spare parts for everything but the currently broken part if the shifter breaks again for ~$70.

As others have said the Centaur 12-32 is sweet (fyi it matches 12 speed exactly sans the 11) and I currently run it with a short cage Record derailleur and a 50/34 crankset without issue on my particular Lynskey frame. Not ideal but it will do big/big without ripping the derailleur apart.

Yes, the consensus is to go with the replacement shifter kit, part EC-AT200 so that the shifter lever matches the one on the left. Campagnolo advises against flushing with any solvents on pre-2014 models. They changed the plastics after that to mitigate some of the degradation problems in case the innards were flushed. Thanks for the input.

I had to replace the right shifter bodies on both a Athena and Veloce setup. I would have preferred that Campy stuck with G-springs and repair-ability. My 20 year odl Centaur shifters work just fine
