• 496 is dope af

    Cant wait to see the black group in place

    Earlier this year (before i stumbled into my saeco build) i thought about doing exactly the same thing

  • Thanks all for the kind words. I don't want any trouble! I only wish to build my silly bicycles very slowly and in peace.

    My primary road bike has 2012 Athena 11-speed, so I was thinking it would be nice if the Look could also be 11-speed so that the two could share wheels, cassettes and chains, of which I already have a bunch. I'm kind of anal about drivetrain wear and the idea of drivetrain components bedding in together from fresh simultaneously, so along with the non-two-tone chain rings I was already also going to buy a new cassette and chain. But with Centaur 10 cassettes and Record 10 chains not being materially less expensive than their 11-speed equivalents, it seems a bit of a waste to buy into 10-speed, especially when I already have 11-speed inventory.

    Instead, I have been thinking about this: if I were to get a Potenza 11 rear derailleur, a post-2015 Record/Chorus 11 right lever body, the matching hood and some 11-speed chain rings, could I make this work? The illustrations for the Record 11 and Centaur 10 lever bodies make it look like the lever blades are cross-compatible, so if possible I'd also want to use a matching Centaur Carbon blade to make things look slightly less weird. Basically:

    1. Is a Potenza 11 rear derailleur compatible with a post-2015 Record 11 lever?
    2. Are post-2009 Campagnolo lever blades interchangeable?
    3. Will the combination of 10-speed front derailleur, 10-speed crankset and 11-speed chain rings yield at least passable front shifting?
    4. Is this something I need to ask in the Campagnolo thread, or is that thread more focused on the concept of Campagnolo than the execution?
    5. Would it even be worth the money to do this?

  • I did some reading yesterday and apparently mixing Potenza with Chorus and up is a no-go due to differences in derailleur spring tension. The claim is that it works initially but drifts out of adjustment, which is something that I can believe if springs are involved. Obviously, then, this necessitates a matching set. There are still 11-speed Chorus and Potenza shifters and derailleurs out there for sale, but even looking at the used market and some-assembly-required shifter options, I don't think I can get either setup to cost less than two times what I paid for the whole Centaur groupset, which kind of feels like a lot for a quality of life upgrade.

    Another thing I encountered during my research is people from the early 11-speed days wanting to upgrade their existing 10-speed setups to 11-speed, like I am trying to do. This post indicates that it's possible if you do a little mod to the derailleur, but the attached images are long dead. So I went down to the basement to grab my 10-speed derailleur to follow along with the instructions, and when I was trying to figure out how grinding down the threads on the cable clamping bolt would help with this situation, it occurred to me that the method outlined is intended for pre-2009 10-speed.

    I went back downstairs to get my NOS backup Athena 11 derailleur, and:

  • I think they're exactly the same. As far as I can tell they have identical dimensions. The Centaur weighs 10 grams more, but it's also painted, and the jockey wheels are probably a little thicker. The spring tensions also seem to be the same (the Athena is maybe a touch stronger, but it also has never been used).

    Therefore, the new plan is to obtain a set of 11-speed Athena levers I found in Ontario that I'd been weighing up buying anyway for spares, and then change the lever blade out for the carbon one from the Centaur shifter. I will also see about also potentially swapping the paddle, but I've got to be honest, it looks difficult.


    I hope it all works.

  • I am, as ever, waiting for parts to arrive. Some things have started to come in, including the Athena shifters and the Stronglight outer chain ring. To my relief, I don't have to grind any of it down because it's close enough in thickness to the original (and Centaur Carbon cranks don't have the weird design that first-gen Athena Carbon did) that the mounting face for the hidden bolt is not a problem. What is a problem, though, is that the Centaur Carbon chain ring bolts (FC-RE303) don't fit because the bolt holes on the chain ring are 8 mm in diameter rather than 10. I'm not a hundred percent sure yet because the small ring is still in Germany, but I suspect that it has threaded bolt holes and consequently I need the FC-SR200 bolts, which are a painful $35.

    On a different topic, this is the one bike that I actually ride. It is a complete, fully functional bicycle with no parts missing or in transit. I am planning to make a few changes, so I wanted to document it in its current state.

  • Best Colnago I’ve ever seen, they usually do very little for me. Nice work

  • Super nice and clean build on the Nago


  • Just stumbled upon this thread and I love it all.
