I just had a question for all members, I noticed in some recent Tour de Georgia photos that Tony Cruz, as well as all of the other Discovery Team Trek bikes looked to have aluminum cranks, most likely Dura-Ace. I was just wondering why they wouldn't use carbon cranks, seems like they would be lighter and stronger and more supple? Are the Dura-Ace cranks more aerodynamic?
It`s because sponsorship I think! Most of the teams with Shimano components have full DA collection (except wheelset, pedals, ...) while teams with Campagnolo have much more mixed components. Bikes won`t be much lighter with carbon cranks and they`re already very near limit..

In addition to the sponsership that Virenque pointed out, the fact is that carbon cranks for the most part are just hype. As far as lighter and stronger, there are only a few carbon cranks out there that beat the Dura-Ace or Record aluminum alloy cranks in both of these categories, and for suppleness, what are you smoking, it is a crank, not a saddle? That said I am building a Pinerello Dogma bling bike, and it has an FSA Pro-Team carbon crank. Why you ask? Well because the FSA Pro-Team was the only Carbon crank I could get in 180mm length and I didn't want a D/A or Record with mere aluminum on my bling machine. Get it? 😉 Performance wise, there is really no difference, and it is primarily a scheme to seperate you from your money, even knowing this, it strangely still works on some folks (like me).
Alllrighty, I understand what you guys are saying. I just thought since they had Bontrager as well they would get some carbon cranks but what you guys said makes much sense... thanks!!
That said, carbon cranks are, in my non-expert opinion, the single biggest ripoff in cycling. And that's impressive, considering that the equipment market in cycling is in general a tremendous ripoff.
Keep in mind not everything is as it appears. Many times a rider will have a bike frame, wheels, or parts rebadged to that of their sponsors.
This is a very prevalant practice in the pro's where a rider may have a preference in the performance/ feel of a certain product but has to make it look like what he gets from his sponsor.
Oh, I could also debate the merits of Carbon cranks but the truth is that it's 25% performance and 75% Chi-Chi factor that gets people to buy these shiny new parts. Really if you have a full Ultegra setup you are set for the life of your bike. Even D/A parts can be considered "wasteful" but that never stopped anyone.
It's all about having fun building your bike the way you like. 😉
