Polished Crank Arms

[Flowta]

Im stoked, thx to Clement, I got a quote of R120 for the set and the guy told me I can bring it Wednesday and have it back Friday!

 

Awesome!!!

 

Do you have to take of the black anodizing first?

 

I have a silver XT crank I wouldn't mind doing.

One thing to consider, once polished it will be raw aluminium and if you live along the coast line it will oxidise. I live in Durban and I have to wipe mine down after every ride to get rid of any sweat that may cause oxidisation. There is a guy in Joburg who says he can naturally anodize and keep the shin. I still need to try a sample out.

I have a friend in PE who polished his 105 shifters. Every so often when they start to look hazy (from the oxidation), he gives them a good wipe down with brasso.

The guy I chatted to regarding the anodizing is: PJ Prinsloo.

His work address is 5 Albatross Street, RhodesField, Kempton Park.

His Email is. splash.anodizing@gmail.com

May be worth trying out.

Nope, I told him its a black XT crank and he just said no probs, bring it in, will save me much more in time and money than R120!

I'd bet they will lose a lot of the shine. Anodising creates tiny pores in the surface of the anodising into which the dye goes if you want it coloured. Anodising tends to give a more satin finish.

 

but maybe there is a way that I am not aware of

Probably better to clear powder coat than to anodize. Polished Shimano parts are normally clear coated AFAIK.

My shoes usually rubs some of the paint off the crank arms (looks really crap), think I will try and polish the arms as well. Will look a lot better and probably stay looking a lot better for much longer. I read that there is some kind of polish you can use (will have to find the thread) that helps with keeping everything shiny for longer, and if the shine goes a lot easier to make shiny again.

Autosol is brilliant metal polish. We use it on our plastic injection moulding surfaces, it keeps a great shine.

 

I didn't know you got a clear powder coating. I did have my polished cranks clear coated using automotive quality clear coat, problem is if you get a small scratch the oxidisation happens under the clear coat and causes more hassle than its worth.

Thats the reason I want to do it as well, black crank show scuff marks and chips easy
