KMC X-10 is the chain I ride with my 10sp Campy Veloce. A trick is... put the bike on the smaller sprockets to create more freedom in the derailleur. Then about 2 links on each side of the master link use a piece of twine to tie the chain together around the master so when the link disengages the chain won't flail around the derailleur and put a chip in your seat stay...take it from me
KMC chains use what is called a Missing link which is a pretty sweet master link. They are not recommended to be reused but many do including me on occasion. With the chain tied together, take a pair of needle nose and pinch the two master link rollers together wihich will disengage the oblong detented holes that distinguish the master/Missing link. Be sure to not push on the sides of the link but rather the rollers centered between the two sides.
HTH...KMC X-10 chain is a good value for a Campy 10s.
To reinstall...use the twine again as a precaution against the link slipping until it is re-engaged...which will be a finite snap. Best technique is to position the link..pushing the two sides together and give a good tug on the pedal with your hand to snap the link into its locked position.
