Biker7, if you want a silver alloy crank Truvativ makes one. Ironically, according the german tour magazine the alloy version is stiffer and 4g lighter than the CF version. Who cares about the weight, but is intersting that the aluminum version is stiffer.
I'd get the black, but I think over time shoe scuffs would wear away the black finish? What does everyone else think?
Here is a picture of a Truvative Rouleur GXP with external bearings. It's a little pricey $225 with BB, but this one can be had in a 177.5 length (I'm used to 180mm)
If you like black rings you could always put them on after the silver wear out.
