    Crank Brothers Cobalt crank

    any one test driven one of these yet

    seems quite light... would it be possible to swap out the rings for something lighter ?


    the CB website says weight = 417g / 565g and if you add up teh approximate weight of teh Truvativ chainrings this also comes to around 148g so it would appear that 417g might be the weight of teh crank and bolts so if you had lighter rings you could be in for a setup in the 670-690g range with a v. light BB.

    I have seen a set here in Aus since May this year. I can tell you they don't look as good in the flesh as the pics. Chainrings look really cheap.

    Beautiful...but

    Great looking crank except for the goofy CB logo. Don't get me wrong, as far as logos go Crank Bros got a good thing going, the placement on the crank arm just looks weird.

    That said, I'm gald to see the brand branching out.

    Just a question: They are constructed by glueing a thin stainless steel sheet metal stamping to an aluminum forged back, right? If so, then how hard or easy would they be to dent due to rock strikes? And what would that do to the integrity of their strength?

    According to Nino's weight, my FSA carbon cranks are lighter (20~39isg grams, not much, but still lighter) and imo look sweet, and they have taken two years of serious abuse, many hard rock strikes, and the only damage is the clear coat getting chipped off in a few spots.

    I wonder if the cranks will be of disposable quality like the CB pedals are?

    It's pretty easy to understand why some of us ask about the limits. We are bigger guys, heavy guys, stronger guys, and these lightweight parts do have limits. A good example is a carbon crank. I've seen FSA cranks with limits for rider weight. Once these components get to a low point in weight they start to become too fragile for someone who is heavy, or strong. That's why I ask.

    But technology is always improving and it may be possible for a lighter component to be designed as stong as a heavier component. This is another reason the question is asked.

    I hope this helps explain the reason for asking about limits. I really do think it's a valid question.
