Yeah that may be simpler because the scheme seems too complicated for my standard brain :p
But I'm afraid the raw aluminium will be hard to polish due to the angles and weird curves.
Hey, I have a 110 purple, and looking for a silver in either size.
A photo is available on my subject, I think it's a displaced one :

Edit : I'm in France too
Hello there,
I just got my hand on a Middleburn RS-3 crankset, which are quite rare in my region, but the spider is purple and I'd really like to replace it by a silver one.
The spider is a 4-bolt on type.
An MTB spider could also be fine.
Of course, trade is possible.
Thanks !
