I find it interesting how few people in the Triathlon world (generally filled with off-the-peg/stock bikes) ever refer to Campagnolo as an option...As an aside, I'd argue that Campy Daytona/Centaur probably provides some of the best "bang for the buck" in road components (at the grouppo level).
With that said, I intend to spec my new Tri rig (recommendations forthcoming from Tom;-) with FSA Pro Team Issue Carbon Cranks...Simply put, they have good weight, they're Campy Compatible (my drivetrain), well-manufactured, and provide that ounce of carbon "sexiness" which I like for my "race" rigs. They are also durable...Many of my teammates raced FSA Carbon Cranks for CCX this past season.
At Interbike this past year, I was VERY impressed with FSA's professionalism. I'd have no problem buying a bike specced with FSA components...It should be noted that a few years ago my opinion would have been different...FSA has simply improved the non-Campy/Shimano market that much.
FSA are sexier than Truvativ...I haven't ridden Truvativ to comment on quality.
