Descending rough roads can be scary though. I recommend it to road racers, climbers, and time trialists. Not for crit riders as much, though, since this sometimes involves tricky maneuvering. I give it 5 stars for road racing, but maybe 3 for crits. Light weight, no winter rusting to worry about.
Bike rides like a block of wood.
Broke after two years. I would not by another carbon bike from Trek. They ride like a block of wood when compared to euro and top us steel frames. Plus the frame is not made for the long haul. Great bike if you have no problems but a top of the line bike from a recognized company doesn't guarantee the support you'd expect.
