AFAM 525 Chain & Alloy Sprocket Kit, 15/39 — 05197403
Price is for the complete kit
AFAM chain and sprocket kit, part number 05197403: an AFAM XS-ring Hyper Reinforced 525 chain (gold) with 106 links, a 15-tooth steel front sprocket and a 39-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 525 conversion, this kit changes the bike from its standard chain size to 525 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.
