Madone 8

I've put about 300 miles on my new Madone 8, and here's what I think. Trek's frame evolution continues by leaps and bounds, and while all my other bikes have the ISO-Speed, this frame takes it a step further with the flexible frame design at the seat post that takes the edge off nasty bumps. The shifting is clean and tight with an immediate response. Overall, this bike hums along on long rides.
