Was trying to choose a new set of cranks. Got a lot of support from all of you at STR. Now I have made my choice. Decide to go with FSA K-force lites. They are carbon cranks. Does anyone have any concerns about using carbon cranks? I will be using them for racing and all around riding. Thanks to all and to all a goodnight.

98% of the carbon cranks on the market are aluminum, just wrapped in carbon. So unless you're doing it for asthetic purposes, get yourself a good set of aluminum cranks.

I also don't think I'd go with carbon cranks (other than maybe on a roadie, but mine has alum.). Unless they are lighter and cheaper than XTR's..

But, I've got a good set of Middleburn RS7 Uno's on my XC rig. I bash my cranks now and then and wouldnt' want to worry about them breaking off or something. I'm sure they are durable, though.

Campy makes full carbon cranks and FSA makes one set, but both are road cranks. I use Race Face on my sub 20lb. XC bike, only because they're cheaper than XTR rings. Carbon cranks are sexy though, I'll give them that.

I debated going with some carbon cranks recently, but opted not to. My complete lack of skill means I have a lot of pedal/crank rock encounters, so that's one part of the bike where I think it's best to stick to metal.

The FSA ones in question are full carbon I-beam design. Only a little lighter then the XTR crank. Was also considering the middleburns RS8's.

in the spirit of the thread, ill throw these in, just cause they're sexy looking:

but in real life i would just go with a nice set of aluminum. XTR are definitely sweet. Even the '08 XT's i currently have are great. stiff, light, and still look pimp.

i hit my cranks on too many things to justify making them carbon. its one of those places you want to be able to gouge without worrying about structural integrity
