ideas on a black crank to go with 7800
 

I am gathering parts to build a custom steel road bike (frame is slated to be built in a couple months). I will be using my 7800 group from my old/crashed cdale along with black thomson elite seatpost/stem, bontrager rxl wheels (black rib/hub, white spokes), a black brooks b15 saddle, black headset, bars, etc.

The one thing I don't like from the 7800 group, in terms of looks, is the crank. I would love to get a 6800 group, but its not in the budget for now, so I am thinking just replace the thing that I don't like. I want a black crank to tie the components into the black feel of everything. I am having a hard time thinking of options though.

A friend suggested (and has a couple) white industry cranks, but I dont know how I feel about them.

I am looking for a double, I think a compact. Pricing is around 300, though lower is always better.

Shimano 5600. Sure, its 105, but darn nice cranks. Not overly expensive either. You could go with a Campy Ultratorque too. Excellent cranks if you don't mind mixing campy and shimano. You could always go with one of the many offerings from FSA as well. Lots of options out there.

Sram makes nice looking cranks, again if you don't mind mixing groups.

I only like the Rival crank from all the SRAM line-ups, you can remove the decal but you need to buy another BB

6600SL cranks came in a dark gray. Not sure if it would match your bike too. I have an R565 black crankset that looks great too.

5750?
