Just received a new frame and am putting the components on. Replacing the chain seems to be the most difficult. Can any schmoe put the chain on without special tools-besides the chain tool?

Depends. Campy has some fancy schmancy $60-$70 chain tool they prefer that you use. Shimano has one also but I have most recently used a general use tool chain for Shimano ultegra stuff.

Installing a chain takes only a few minutes.

Getting the chain length correct is critical, but simple. With campy 10 speed, you only get one chance to get it right. The campy permalink tool should be used to insure proper seating of the permalink pins. Instructions are include with the chain and the permalink tool. A standard chain breaker is also needed to remove extra links.

Two simple tests will determine if the chain is the correct length. First, it must not hang loose in the little ring, little cog combination. If there is no tension on the chain in the little ring, little cog combination, remove one link at a time, until there is. When the ends of the chain are brought together, some movement of the lower pulley should occur, indicating tension is being applied. One more link may need to be removed, beyond the point of absolute minimum tension, to keep the chain from rubbing on itself as it passes under the upper derailleur pulley. Once this is done, the chain is set to the maximum useable length. Removing additional links will do nothing but reduce the derailleur's capacity. It won't help keep the chain from skipping or jumping (a common misconception).

Second, the chain must be long enough not to over-extend the rear derailleur when shifted to the big ring and biggest cog combination. If the chain is set to the maximum length as described, it should always pass this test, unless your setup exceeds the derailleur's stated capacity.
