OK, to clarify:
2007 Specialized Tricross Comp: triple crankset, semi-compact frame. the frame gives you a more upright riding position and more comfortable. The Comp has much better components AND a better frame then the Sport. And no, the parts and wheels of the Comp are not finicky. As a matter of fact, based on my '06 Comp, they're quite durable and bombproof. This is my first time with a compact crankset (on the '06), and it's OK, but I do miss the versatility of the triple.
Sport or Comp you can't go wrong.
