Campagnolo 12-Speed

That looks very interesting.
Design is exactly the same as Edco and that other taiwanese company I can't recall the name.

As you appear to live in Vicenza where Campy HQ is located - can't you try to ask someone around for help?micky wrote: ↑Sun Jan 09, 2022 9:13 amOne question for the EPS users; yesterday I was out running and suddenly the rear derailleur didn't work anymore.
I though it was the battery but once at home checked with the app and it said 44%.
As I put the bike on a bike stand and tried to check everything, MyCampy app showed a "there's a problem" on the screen.
Of course checked cable and then put on charge to bring it up at 100% but still not working, changing few gears and then stop again.
I did a zero setting for the RD and fingers crossed, it seems to work again.
Anyone experienced this before?
Of course, but those lazy bastards don't work on a Sunday morning when I posted the question so I'd though I'd ask here as it's a forum for exchanging experiences.
Thanks for your help.

Yes I'm really sure. One manufacturer of carbon parts here works directly with them and he was the one who told me that first hand.
There are EDCO parts that are done in Taiwan (namely some wheels), but even those EDCO wants to move back to Europe again.

I'm afraid your contact at EDCO may have been misleading you. I've owned 11s monoblock cassettes from Recon, Presta and EDCO and can tell you that the machining is identical.
Do they all have the issue of the extra machining for the shift ramp on the 12T going all the way down into the "floor", weakening that "floor" right next to the point where the 11T is weakened by its own ramp machining? I've had a tooth give in to chain tension there. Curiously without any noticeable change in shifting or transmission (I guess I might be a bit insensitive?)
In an case, identical machining is obvious, but it could still be the same program running on different CNC sites. I could imagine that shift ramp weakening to be a setup issue or a side effect of tool wear compensation but that's just a clueless layman guessing.

I'm not knowledgeable enough to pick up on that sort of thing but these cassettes trade lightness for shifting performance and durability compared to OEM. From memory, their 11-23T definitely didn't shift as nice or last as long as CS-9000.usr wrote: ↑Tue Jan 11, 2022 5:53 pmDo they all have the issue of the extra machining for the shift ramp on the 12T going all the way down into the "floor", weakening that "floor" right next to the point where the 11T is weakened by its own ramp machining?

If you look at, say, the Chinese EE brakes, you'll notice that all parts are identically machined. That doesn't mean that the original EE brakes are done at the same factory. They aren't!StiffWeenies wrote: ↑Tue Jan 11, 2022 1:41 pmI'm afraid your contact at EDCO may have been misleading you.

Chinese plants just reverse engeniers a bunch of stuff and a monobloc cassette is easy to replicate if tou have the right tools to do it

Recon is a full fledged OEM with proper engineering and manufacturing capabilities. I also won't tolerate your word salad about reverse engineering. There is absolutely no money to be made on reverse engineering a bunch of obscure bicycle parts that only a couple enthusiasts on a forum like WW would buy. To suggest that there is even a business case for such a thing is laughable at best. The real money is in supplying parts to complete bikes for name brands like Giant/Specialized or big retailers like Decathlon/Walmart but that's a topic for another thread.naavt wrote: ↑Tue Jan 11, 2022 8:30 pmIf you look at, say, the Chinese EE brakes, you'll notice that all parts are identically machined.

Back on the topic of EDCO, several WW posters have written in the past that EDCO cassettes are made by Recon. One even stated that Recon themselves suggested that they were the OEM.

Slower. Where Campag usually makes the chain jump immediately, ramp or not, with the ramps only there in case the shifting happens to be an unlucky one, I felt like the monoblock would usually wait until the ramp happens to pass through at the derailleur (might as well be lower number of ramps per revolution, and could be unnoticeable for users of motor shifting).
Most noticeable when rolling to a stop: I often had to get going with a downshift still in progress after preparing for the stop in the accustomed distance, that went away immediately when I got back to the regular cassette.
When Campag does the shift immediate thing, it does so with a loud clank. That clank is still there with the monoblock, so not all is lost
