🛠️ Chain Engagement on Powder-Coated Sprockets: What to Expect
If your chain doesn’t seem to fit or engage properly on a new powder-coated sprocket, don’t worry — it’s a normal part of the break-in process.
At Milk Racing, we often receive questions about initial chain fitment on custom-colored sprockets, especially powder-coated and candy-finished versions. Here’s what you need to know:
Why the chain may not fit perfectly at first?
Powder coating adds a thin protective color layer over the raw sprocket surface. While this layer enhances looks and resists corrosion, it slightly increases the overall dimensions of the tooth profile and valleys.
As a result, your chain may not seat or engage properly during the first few rides. You might notice a slight misalignment or that the chain feels “sticky” on the sprocket.
What happens during break-in?
During initial use, the chain gradually wears through the powder-coated layer in the high-contact areas — allowing proper alignment and engagement between the sprocket teeth and chain rollers.
This break-in process usually resolves itself within a few rides and does not affect the long-term durability or performance of the sprocket.
💡 This applies to all powder-coated sprockets, including Candy finishes, which use the same coating method.
Final thoughts
Powder-coated sprockets are a great way to add style and protection to your build. Just keep in mind that the chain may not fully engage at first — this is normal and expected. Once broken in, your setup will perform just as reliably as any raw or anodized sprocket.
