Has anyone used the new Veloce or Centaur long cage derailleurs yet?

No, but what's the real question? Just the same RD, with a longer cage. I have used Campy 10 long cage RDs and they work the same as the shorter ones, just more wrap capacity. Many people don't seem to realize that the shifting occurs between the upper jockey pulley and the cassette, so shifting performance is no different. The longer cage just takes up the extra chain slack - that can occur slowly and have no effect on power transmission.

That was the real question. I'm looking for input on the new long cage derailleurs.

I do understand how a derailleur works. Seeing as this is completely new model I'd like to ask before I buy. Thanks for the answer though.

duh...

Since the cage length only adds wrap capacity, what do you expect? Kind of of a dumb question, unless you're mixing shifters. There is some evidence that the RD's made to be used with powershift levers may not have enough spring tension to make good shifts to smaller cogs, if ultratorque shifters are used.

Actually, I'm using a set of 2000 - 2006 Ergo levers.

Yes, like one more poster in this thread, I have not tried the new Campy long cage derailleur. I have, however, used several Campy long cage derailleurs in the past. My assessment -- 1) they shift slightly more slowly than the short cage ones, though not enough to matter. 2) perhaps more important, they hold the chain loosely enough to make it so that loose-chain situations, such as small-cog/small ring combos, are more likely to cause the chain to slap the chain stay when you go over a bump.

Thanks, that's the kind of information I was looking for.
