cleaning/restore campy record strada cranks

i have a crankset i want to bring back to "new"...or at least, all pretty and shiny.

it appears there is some coating, which, with all the nicks and stuff is worn off in places. at first i thought i could polish out these blemishes, but now it looks as if the polishing makes it worse. it looks as if the subdued/flat greyish finish is the coating.

what is the preferred method of restoring campy strada cranks? i know this may be lacking info, i'd be happy to supply more, if i knew what that should be.

i've used a polishing wheel with an air compressor, as well as mothers mag&aluminum polish, and mothers power something squeezy aluminum polish. the polish didn't turn black on the cranks, but did on the cloth.

I just did this Campy seat post which wasn't in very good shape.
I used an eraser as a block. I used 600, 1500 and 2000 grit sandpaper.
Then I used Mothers aluminum polish.

Grew up on the mean streets of the East Side, Alter & Mack (cut you and gut you before you hit the ground, even in my senior years...), now my time in MI is in A2. In PHX I'm around Cactus and Tatum.

FLW & Shea is too rich for me. I can only afford Italian bikes, not Italian cars

That's a Nuovo Record crankset. Strada just means road.

I polish my parts pretty much the same way Ray Dobbins does except that the really beat up parts get sanded before buffing. I use a quarter sheet Porter Cable sander and then I hand sand up to 400 grit and then I use super fine steel wool. My buffing wheel is mounted on a 16" drill press.

This crank was in really bad shape when I started:



Don't leave the oven cleaner on too long when you remove the anodizing or it will begin to eat the aluminum. you may have to treat the part more than once to get all of the anodizing off. You'll know all of the anodizing is gone when the part turns uniformly black.

Nope, not in those condos. but just down the block from the Dubliner!

Must have been those apts by Sweetwater Park , just down from REI, where the guy got capped in the parking lot. Tweakers.

As Ray Dobbins' article will tell you, if you haven't read it already: the crank/spider is clear anodized; where it's been worn off, you can use metal polish to shine the aluminum up, but polish will do very little to the anodized area. Campy's special formula for polishing + anodizing can't be "matched" by cleaning with metal polish. If you want an even finish, you have to remove the anodizing. Then you can shine it up, but it won't ever look like it did in the bike shop/factory; and it will be more susceptible to corrosion. That's not a problem if you take care of your gear and keep it waxed/oiled/clean. Aluminum oxide looks whitish, and that's what you want to keep from forming on your parts.

As Ray Dobbins also tells you, there are a lot of Campy Record components (hubs, for instance) that are not anodized; they're easier to clean up with just polish.

If you're a fetishist and can't leave well enough alone, then you could strip the anodizing, polish (but do not wax) and have the part re-anodized at a finishing shop. It probably will never look like it did originally, though; there's just something about that Campy process that's unique (at least to my eye).

Yeah I did pretty much the same thing with these campy 'Athena' aero brakes.

The first pic is how they looked when I got them. NOS straight out of the box.







~ btw - you done a good job on that crank.

If you really insist on getting all weenie technical about it, they're Record strada cranks with Nuovo Record chainrings.

Thanks. The brakes look great! I'm just finishing up a set of Super Record calipers. I bought a NR triple from Hilary Stone that he said was polished, but it appears that it was polished and then chrome plated!
Now I have to get the brakes and other parts polished really bright to match it.

Be sure to check that Campy crank for cracks in the usual places. That set looks like it has seen a few miles!

Since the cracking issue was brought up, and not trying to hijack the thread...would anyone have a picture of a crank that has been "stress relieved"? I have an idea on what they should look like. I just want to see what others have done.

Anybody?

I'm interested myself now that I've got two of them. One is from 1975 and has been chromed, and I'm sure that doesn't help the situation.

Hi Dirtdrop,

Nice job - just be careful with the steel wool. One should not use steel wool on aluminum/alloys as microscopic particles of the steel will embed allowing for disimilar metals corrosion to begin. Learned all this from my days as an aviation mechanic. Will try to post a pic of my Campy crank later.

That hasn't been a problem, but they get a lot of time on the buffing wheel after the steel wool. Maybe that removes those microscopic particles.

I was about to post a picture of my new triple, but it will have to wait until the camera batteries charge.

As someone who designs a lot of dissimilar metals into buildings, I have to say that I think the whole galvanic corrosion thing is overdone where you're talking about things other than ships. Most of the studies and quantification are done for dissimilar metals in a good electrolyte (seawater).

Steel wool particles will rust however -- nothing to do with their being embedded in aluminum -- and that's unsightly. In building construction projects, it's sometimes a problem that an ornamental metals fabricator who's clueless will finish stainless steel using the same tools used for carbon steel. Then the "stainless" will rust just like carbon steel; it's not a pretty sight! Again, this has nothing to do with the dissimilarity of the metals, just that the (very thin but effective) chromium oxide layer that protects stainless steel is prevented from forming continuously over the surface, by the presence of particles that are carbon steel, without the chromium content that enables the oxide to form.

Slightly off-topic, but how well does Simichrome metal polish work on components (such as cranks) without stripping the clear coat off? I'm not looking for a mirror finish, just a little bit of shine.
