Refinishing cranks?
 

so i've had a set of dura ace 7701's for a while, and they've been beat up and rubbed up(dura ace logo is no longer there). I was thinking about polishing them up, but im working on a new build where the parts are mostly black, and i was wondering if there was a safe way to powder or paint the cranks? or should i just polish them up, and have polished cranks but black everything else?

powder coating will come out bad, because they're aluminum. you can polish them, or use a wet paint.

Nagrom is a pro at polishing stuff. Maybe he can give you some pointers.

edit: too late!

Cranks aren't hard, I polished my 7710's.

you know, its just hard to take a matte black finish, and try and take it to a mirror finish, especially when its a big ass rim.... hahaha.

any tips on wet painting it? im guessing rattle can would rub off after the first week or so :\

um, pretty much all of it will if you don't do it professionally. take it to an autobody shop or something.

aluminum can be anodized right? there a place that professionally anodizes stuff a couple miles from my house, im sure it'd be super cheap to do a small job like some tiny crank arms

That'd be the route to go.

alright sweet, thanks!

Let us know how that goes. What do you consider super cheap?

ETA: most places won't ano used parts. Things need to be super clean before putting them in the tanks. Cranks pick up a lot of crap in the the threads that could be hard to clean out to the satisfaction of the person in charge. But as I said, update us.

They will probably media blast it beforehand.

I can't believe I'm doing this:

You can also use a dremel with the polishing wheel, and some toothpaste.

Im just sayin, don't hold out hope.

lol.

Here's a link from the "Start Here" thread you started: http://www.bikeforums.net/showthread...40#post3677840

I'd stay polished if I were you. Polished cranks generally can suit any build while black cranks, not so much.
