Found some on Ebay, but nothing for SRAM or Campagnolo on the regular US websites. And, the SRAM Apex group cost (edit) from the UK was 1/2 that of the same set on Flea Bay.

Why the US aversion to selling sets ?

Why, how is it logical that a Taiwan set from Taiwan costs more than the same set from England ?

Totoboa scratches his mind at these things.
