Hey there
The Afam sprockets ( ie the gold ones) are hard anodised aluminium they will wear at a slightly higher rate than the steel ones and are a little tougher on the rollers of the chain as hard anodising is rather a course finish .. ,,They do get some really good milages though ,
you should be able to use those catalouge numbers to find online / in NZ a source.
You can also get chains in differing colors , red , green. blue etc
