This is an oft-made error. Retailers, (with the exception of a limited number in Italy), don't have a direct relationship with Campagnolo, any more than they do Shimano, or SRAM.beeatnik wrote: ↑Sat Jul 07, 2018 7:45 pmMutual admiration, Cal.
So, here's what's a little confounding (weird) to me. That C59 has one of the few (2nd?) 12s Record groups in France. The shop which installed it must have an established relationship with Campagnolo. And, yet, based on the flickas posted here, the people who worked on that bike haven't cracked a Campagnolo manual since the introduction of C Record. Based on my experiences with 2015 Revolution I'm beginning to believe that the only competent Campagnolo wrenches are single client concerns, ie, home mechanics.
They have a relationship with an importer-distributor. Importer-distributors are usually selling a variety of brands and in most cases (there are notable exceptions), they are not all-knowledgable about any one brand (Campagnolo in this example) as they simply have too many brands on hand for that to be possible.
Campagnolo's way around this is to have local branches like Campagnolo NA, France, Germany or Spain, or to have very trusted local resources who are treated like branches (ourselves in the UK, ICC in the Benelux) where the technicians are directly trained at Campagnolo. These guys are there to train and support the Service Centres (generally one or two per country) which are linked to the main import-distributor(s).
In order to qualify as a ProShop, a retailer needs training, generally conducted by the local branch, or I believe in some cases by the main distribution channel in that market (in France I believe only by Campagnolo France).
If a ProShop is unsure about an issue, their first point of reference is the documentation - both that provided with the components and / or freely available online, or that provided at the time they received their training (sometimes more detailed and extensive but often a "beta form" of the public documentation). The next step is to refer to a SC. If the SC is not sure / doesn't know, they should refer the matter to the local branch of Campagnolo, who are in direct and daily contact with the factory.
There are excellent Campagnoo mechanics all over the world in good, reputable businesses - but one of the key problems that faces the industry is that training costs money and the race to the lowest possible retail price precludes the possibility for retailers to engage in a proper training process. This feeds back up the supply chain. Hence, we end up with the (partially) blind leading the blind and no-one is happy. The consumer has kit that doesn't work properly, the retailer has an unhappy client and the manufacturer's brand is damaged because the consumer's experience of the product is poor. In my private opinion, online selling has materially worstened that position but now we are in that position, the fix is far from clear - but that is a whole other discussion. What is for sure is that problem solving online by commitee, where we are dealing with highly expensive, well designed and thoroughly tested products is not always helpful.

I imagine that just means it's dual-sprung like older pre-shadow Shimano servo-pantograph/Simplex prestige derailers. I suppose despite the fixed number of cassettes it's meant to be compantible with, Campy felt the cassette wasn't linear enough for a single sprung derailer, hence the need for additional "self-adjusting" over the just having a slant parallelogram.

It's not just the spacing of the chainrings that's of consequence, or even the altered chainline, it's also the new derailleur and the shifters as well... and how they move everything between the chainrings. For instance, there's now two distinct poistions that the front derailleur has when on the big ring. Prior to this, there was only one, no trim (which was great) and you could use all the cogs cleanly. So, if you just throw an 11sp crankset into a 12sp drivetrain, with the 12sp front derailleur and shifters, then there may be some incompatibilites there. I've a lot of unanswered questions in my own mind at the moment (many of the same ones I had when they came out with HO cranks, etc), which probably won't get resolved until I have a 12sp group to really test out for real. But I do have some ideas mulling about in my mind for sure.

I'm totally with Cal on that one. I just squinted myself crosseyed and I can't see anything remotely conclusive (or even suggestive) in that pic. And since the pic from the other side definitely doesn't look like the link is in the right place, smart money still goes with it not being in the right place.
Edit: And now I've seen the next page. Wow!
My depth perception was severly lacking.
Exactly. It’s the old Simplex principle, but in this case it’s here to make the system as foolproof and robust as possible2lo8 wrote:I imagine that just means it's dual-sprung like older pre-shadow Shimano servo-pantograph/Simplex prestige derailers.

What chainring are you using? probably your chainrings are also suppose to work with 11spd?
I have Rotor crank too with Rotor q-rings. So noq or q might be no issues but will 11 or 12 spd be an issue?
