Euro value affects UK exports in other ways. Ribble is buying Campy from a Euro zone manufacturer and we see the savings reflected. Also, I bet a lot of Ribble's customers are on the continent, so reduced sales from the weak Euro has probably affected prices, too.

Either way, you'd be crazy to not buy a new groupset from Europe if you were in the market right now. A friend of mine just bought a full Athena group from the LBS and paid almost exactly twice Ribble's price.
