OK....sorry if this is a dumb question but what is the advantage in having carbon cranks. Weight? Stiffness? Is a carbon crank lighter and stiffer then a Dura Ace crank? I just purchased the new 5.5 Madone with full Dura Ace except for the compact carbon crank. I want to switch to standard. Not sure if I should go with carbon or the Dura Ace crank...
On a test by that Aussie bike mag(can't remember the name), they tested carbon and aluminum and some aluminum were stiffer than some carbons and vice versa. Like all carbon 'stuff', it just depends.
Secondly when the marketeers say lighter, stiffer', they imply that ya just can't ride w/o this new gadget, the old stuff being so 'soft, flexy, heavy', which of course, is not true. same for the BB30 bottom bracket silliness.
Like a guy at interbike once told me when I pointed to a piece of his company's gear and asked, 'what's that for?', he answered, "it's for selling'...
I have an aluminum crank on one bike and a carbon on another and I can't tell any difference.
