I have been riding Shimano my entire life, but recently I acquired a bike with Campy record 10 speed groupset from a colleague at work. I have to admit I know very little about Campy, close to nothing. I tried reading around and various sorts of Google Fu but what I usually find is either too specific to problems people having or to vague and irrelevant. I have a hard time finding some nice intro to Campy / their groupsets, some kind of wiki style articles. I would imagine with such thing as Campagnolo that arises a lot of passion and enthusiasm in different people, it should exist but I can't find it.

Also, just looking for simple question turns out to be harder then I thought. For instance, I know that most ultegra 10 speed cranksets will work with 9 speed shimano drivetrain. But is it true for Campy, will for instance, 11 speed compact super record crankset work with 10 speed record drivetrain? Or another one, the bike came with 11-25 cassette, what would be the most cost-efficient way to make it more hill friendly? (it already has compact cranks). You insightful advice would be much appreciated!
