AFAM 520 Chain & Alloy Sprocket Kit, 17/43 — 01577405
Price is for the complete kit
AFAM chain and sprocket kit, part number 01577405: an AFAM XS-ring Super Reinforced 520 chain (gold) with 110 links, a 17-tooth steel front sprocket and a 43-tooth aluminium rear sprocket. Chain and both sprockets come together, so they wear in as a set.
AFAM says its front sprockets are made from C45 steel with induction-hardened teeth. The rear sprocket is aluminium — lighter than steel, but it wears faster.
Where the table below says 520 conversion, this kit changes the bike from its standard chain size to 520 pitch. That is why the chain and both sprockets are replaced together — do not mix them with your old parts.
Check the tooth counts against your current sprockets before you order: a different count changes the gearing. Not sure? Email us with your bike and we will check it for you.
