I have this year's Madone 4.7 WSD, which is the TCT carbon. The ride is awesome! I came off a Giant TCR to the Madone, and the Madone has a much better ride IMO. It's responsive without being twitchy. I'm very pleased with it. I am a lightweight but the roads on my training grounds are old chipseal and the Madone smooths them right out.

As for cranks, I ride a triple because I do a lot of riding in the mountains. Like a previous poster said, it shifts like butter. The new Ultegra is much better than previous versions. Mine came with a double but the shop swapped it for me. On the Giant I had a compact double and I missed the bigger big ring for fast descents - it seemed like I ran out of gears before everybody else. With the triple, I've got the best of both worlds - a bigger big ring and smaller small ring.

As for wheels, mine came with the Bontrager Race wheels. I've got over 1300 miles on them so far and they've been great. No complaints at all, no need for truing.
