Has anyone here setup their Campagnolo double front derailleur with no grinding of the chain on the cage when in ANY gear?
My specific setup is:
-Wipperman Connex 10 Speed Chain (campy 10 compatible)
-Campy 11/21 cassette
-Stronglight 39/53 chainwheels (Campy 10 compatible and NOT bent)
-Record front derailleur (clamp-on)- I've tried both the Campagnolo Record pre-2004 (aluminum cage) and the new carbon cage one
The issue is that I cannot get the chain to stop making contact with, and in effect, grinding against the derailleur cage when in either the largest or smallest cog. Basically, the cage just doesn't appear to be physically wide enough to allow the entire range of cogs to be shifted to without the chain touching. One example of the impossibility of all this is that I can setup the front derailleur to shift from the 39 chainwheel to the 53 chainwheel while on the 11-tooth cog with the smallest possible distance between the cage and the chain that results in silent operation, but after shifting to the 21-tooth cog, the chain will begin to grind against the cage. And again, I've tinkered with the physical location of the derailleur (both the angle of the cage to the chainwheels/chain and the height on mech on the frame seat tube) in most every way. And I know it simply shouldn't be this difficult, the rear setup was swift and flawless. So I'm guessing I just have an incompatibility problem (check out the setup above). Maybe the wipperman chain is just too wide, even if it's just a few millimeters.
I'll make a stop off at a LBS to checkout their setups and ask some questions, but I think I've checked in the past, and they too, would grind to some degree (at least the display models). Unless someone knows why this is an issue, I'm just going to take the entire thing off and shift with my finger when necessary. Which might sound a bit ridiculous, but not really an issue for me, and even desirable in some ways, since I really only change chainwheels before and after big climbs. Plus, the bike runs completely silent, it makes for a lighter bike with less maintanence/cost, and not having one won't make the difference between ending up with the yellow jersey at the end of the day (at least not for me).
Thanks for any suggestions.
