Dick wrote a review of Giordana Forma Red Carbon Bib Short - Men's on September 22, 2009
After trying Castelli and Craft's top offerings, the Giordana Forma Reds are my favorite bibs to date. I picked up a pair of the top-end Carbon version on sale here on RC, and to be honest, I prefer the standard version.
Both bibs are equivalent in sizing and comfort (same chamois, same fit, etc. Just a different material), but my long torso causes the less elastic FRC straps to dig into my shoulders a bit more than I'd like. Otherwise, both shorts feel like a custom fit using a size larger than I normally wear.
Overall, these shorts sport a great length, nice compression, and superb comfort. Still, I'd suggest going with the cheaper Forma Reds to save some scrill.
