I have the Nashbar Cyclocross Carbon Fork on my Cross bike and I am very pleased with it. I weigh 240 to 250 depending on my lifting program, so differences in ride are not imagined. I ride very hard, load up with cargo, do short tours, and I also use this bike in paceline training. The thing that made the biggest difference with the AL frame on my cross, however, was the Thudbuster ST seatpost.

The Thudbuster is amazing, and it seemed to synergize with the carbon fork and make it even more relevant. The combo is a complete killer and I highly recommend them both together. You will have the best of both worlds with a stiff and responsive frame without nearly as much of the brittleness.
