4. The Trek-Campa-BB-Set went in easily on the drive side and with tough love on the non-drive side. Now the crank spins with different friction in different positions... I presume, just as in Calnago's case, that the cut-out was not perfectly round. Or will it suddenly rotate freely once the crank is correctly tightened? :noidea:
In my experience this type of issue is because of a damaged bb cup or sleeve. Remove the cranks and inspect with a light. If nothing abnormal is visible, CAREFULLY remove the bb and inspect it for damage. I have seen misaligned sleeves cause cups to crack; causing a tight spot only during part of the revolution of the crank. When in doubt take it to your local dealer for a diagnostic. Good luck.

Thanks! Seems to be ok. Torqued up, the cranks are turning fine!

So seat tube it is. Here my take at Campa's rather expensive insertion tool:

Things are shaping up. I connected all the EPS parts today for a test run, externally. First, the interface flashed green rapidly (problem with rear derailleur or power unit), but started to shine a steady green when I attached the charger. So I hope we're good 😬

As to the front derailleur, I am wondering about the best way to route the cable: externally under the BB, or try to bend it around the FD so it enters through the Di2-port?

All went well - everything is connected, FD and RD are shifting, producing satisfying "bzz, bzz" sounds.

On the to-do list:
- putting oil into the brake systems
- re-installing the Isospeed seatpost assembly. Question here: Does anybody know how much torque should be put on this bolt (the "axle" of the Isospeed) or any other info regarding re-assembly?

- finding a solution for mounting a rear light on the seatpost (not immediately below the saddle - that's where a saddlebag goes.

In the end, all went well. Completed it yesterday.
8,8kg with pedals (not that I care), size 62.

Can I ask what saddle you are using?

Hey XCproMD, thanks! Yesterday I rode it for the first time, starting cautiously in case something would come up and becoming more and more confident. 80km with plenty of wind. I think it rides great! EPS is fantastic. The bike feels very efficient and stiff, transferring power on the pedals into propulsion. And yes, I had the distinct impression that it cuts through the wind.
The saddle is a Prologo. Not sure if I will keep it; yesterday it did not go too well with the chamois of my winter bibs (Pearl Izumi) towards the end of the ride. I'll have to test-ride it with other bibs, especially Assos.

Oh, and now I understand what people mean with Campa hydros having great modulation when breaking. It is indeed wonderfully linear while staying effortless, from light to hard breaking.

That is the frame and size I was looking for last month. Ended up with another frame or I would be buying that one. The red with giant white logo is hideous though.
I so agree. I'd be embarrassed to be seen on a rolling billboard. I'm from America and I'm applauded our lack of sence of basic aesthetics.

Well, I gave the EPS FD stiffener a try. First of all: it is tiny, tiny, tiny!!
B18DD191-571F-490B-882F-B71F42C80EAB.jpeg
It did not quite fit where it is supposed to, on the inside of the FD, and required some adjustment with a file. Also, the tiny screw that fixes that little bobbin to the FD had a head that was way too big to go where it's supposed to go - some Dremel love, this time.

Thus having thoroughly voided any chance to send this 63€ item back, I mounted it.
With the facepalming effect that it's not compatible with the Madone frame. When it's mounted, the FD won't align straight.
