Eh... Return them and just use standard Shimano/Jagwire or in your case, Campag cable kit IMO.

I've used the ultra slick, sealed etc cable sets in the past, so over them. Now I just go to the local shop, tell them I need cables and housing. Half the price of whatever set I can get on eBay or Amazon. I don't care if it's jagwire, sram, or shimano, they all shift great. Now that even ALU bikes have internal cabling, no need for these sealed systems.

My 2cents regarding the obnoxiously expensive cabling kits.
